Katrina Firlik is a neurosurgeon, one of only two hundred or so women among the alpha males who dominate this high-pressure, high-prestige medical specialty. She is also a superbly gifted writer–witty, insightful, at once deeply humane and refreshingly wry. In Another Day in the Frontal Lobe, Dr. Firlik draws on this rare combination to create a neurosurgeon’s Kitchen Confidential–a unique insider’s memoir of a fascinating profession.

Neurosurgeons are renowned for their big egos and aggressive self-confidence, and Dr. Firlik confirms that timidity is indeed rare in the field. “They’re the kids who never lost at musical chairs,” she writes. A brain surgeon is not only a highly trained scientist and clinician but also a mechanic who of necessity develops an intimate, hands-on familiarity with the gray matter inside our skulls. It’s the balance between cutting-edge medical technology and manual dexterity, between instinct and expertise, that Firlik finds so appealing–and so difficult to master.

Firlik recounts how her background as a surgeon’s daughter with a strong stomach and a keen interest in the brain led her to this rarefied specialty, and she describes her challenging, atypical trek from medical student to fully qualified surgeon. Among Firlik’s more memorable cases: a young roofer who walked into the hospital with a three-inch-long barbed nail driven into his forehead, the result of an accident with his partner’s nail gun, and a sweet little seven-year-old boy whose untreated earache had become a raging, potentially fatal infection of the brain lining.

From OR theatrics to thorny ethical questions, from the surprisingly primitive tools in a neurosurgeon’s kit to glimpses of future techniques like the “brain lift,” Firlik cracks open medicine’s most prestigious and secretive specialty. Candid, smart, clear-eyed, and unfailingly engaging, Another Day in the Frontal Lobe is a mesmerizing behind-the-scenes glimpse into a world of incredible competition and incalculable rewards.

Chapter One

Chapter 1


Scientist and Mechanic

The brain is soft. Some of my colleagues compare it to toothpaste, but that's not quite right. It doesn't spread like toothpaste. It doesn't adhere to your fingers the way toothpaste does. Tofu--the soft variety, if you know tofu--may be a more accurate comparison. If you cut out a sizable cube of brain it retains its shape, more or less, although not quite as well as tofu. Damaged or swollen brain, on the other hand, is softer. Under pressure, it will readily express itself out of a hole in the skull made by a high-speed surgical drill. Perhaps the toothpaste analogy is more appropriate under these circumstances.

The issue of brain texture is on my mind all the time. Why? I am a neurosurgeon. The brain is my business. Although I acknowledge that the human brain is a refined, complex, and mysterious system, I often need to regard it as a soft object inhabiting the bony confines of a hard skull. Many of the brains I encounter have been pushed around by tumors, blood clots, infections, or strokes that have swollen out of control. Some have been invaded by bullets, nails, or even maggots. I see brains at their most vulnerable. However, whereas other brain specialists, like neurologists and psychiatrists, examine brain images and pontificate from outside of the cranium, neurosurgeons boast the additional manual relationship with our most complex of organs. We are part scientist, part mechanic.

The scientist in me revels in the ethereal manifestations of the brain: the mind, consciousness, memory, language. The mechanic in me is satisfied by the clear fluid that rushes out of the end of a tube I insert into a patient's brain to relieve excessive pressure. In everyday surgical practice, the science may take a backseat to the handiwork, and that's okay. If you have an expanding blood clot in your head, you want a skilled brain mechanic, and preferably a swift one. You don't care if your surgeon published a paper in Science or Nature.

I'll give you an example of a most straightforward and manual case. I was paged to the emergency room a few years ago during my training and received the following brief report over the phone: "carpenter coming in with a nail stuck in the left frontal region of his head . . . neurologically intact." What is going through my mind at this point? Do I hark back to my studies of frontal lobe circuitry and mull over the complex neural networks involved in language and memory? No. I'm thinking concrete, surgical thoughts: nails are sharp; the brain is full of blood vessels; the nail may have snagged a vessel on the way in. These thoughts are instantaneous, of course. I spell out the simple logic here purely for effect.

What I encountered in the ER was a young man, in his thirties, sitting up on an emergency room gurney. Perfectly awake and alert, arms crossed in repose and still in his construction boots, he smiled nervously when I walked in. Was he the right patient? He looked too good.

He was the right one. The carpenter explained that he and his friend were both on ladders along the side of a house. His friend was working a few rungs above. They were driving heavy-duty nails into the siding with automatic nail guns. His friend's hand slipped upon firing in one of the nails, and the nail entered the left frontal region of my patient's head below. For the first few moments after impact, the carpenter doubted what had happened. Although he noticed a stinging sensation within a split second of his friend's slip of the hand, and heard the loud expletive coming from the same direction, there was no trickle of blood and he felt nothing unusual as his fingers frantically searched the top of his head. He wasn't sure if it went in. His friend knew otherwise.

Upon close inspection of his scalp, past his short crew cut, I could see the flat silver head of the nail, not quite flush with the scalp, but a bit deeper. Apart from the nail, he looked great. I performed a quick five-minute neurological exam and found nothing wrong. I sent him down the hall for a CT scan. The nail entered his brain perfectly perpendicular to the surface of the skull. It had been driven a good two inches into his left frontal lobe. Luckily, it didn't snag any sizable blood vessels along the way. There was no evidence of bleeding within the brain. Unlike the more common gunshot wounds we see, this was a respectably neat and clean penetrating injury.

At this point, my biggest fear--bleeding in the brain from entry of the nail--had been put to rest. Now, do I take a breath and mull over any complex scientific issues at this point? Am I exercising my formidable brainpower as a brain surgeon? When people say, "it doesn't take a brain surgeon," they refer to the assumption that we are the smartest ones around. Have I demonstrated this superior intelligence so far? Again, my thoughts return to the practical and concrete. We need to get the nail out of this guy's head. It didn't cause any bleeding on the way in. We need to avoid bleeding on the way out.

I walked out to the waiting room. His wife was there and so was his friend, who was pale and despondent, looking down at the floor. I tried to cheer them up a bit. Yes, the nail entered his brain, but his brain function, as far as we could tell, was normal and the nail caused no bleeding. Without looking up, the friend opened his hand and offered me a large silver nail that had been warming in his palm, the same type embedded in my patient's head. "I don't know . . . it might help you guys to have one of these . . . so you know what you're dealing with." I hadn't been able to tell from the scan that the nail had two copper-colored barbs sticking out from the shaft at acute angles. I'm not a carpenter, but I figured that the purpose of the barbs was to ensure a strong hold. I thanked him and pocketed the nail in my white coat. On my way back to the ER, I ran my fingers over the pointy barbs and thought about the issue of bleeding again. Avoiding and controlling bleeding are elementary and pervasive themes in surgery--not quite the stuff of rocket science, but critical nonetheless.

After calling on the appropriate team, including the supervising neurosurgeon and anesthesiologist, I took him to the OR, shaved a small patch of hair around the nail head, and made a short linear incision in his scalp, down to the skull. There are no how-to entries in our textbooks regarding removing nails from heads, so we improvised using common sense. We drilled out a disc of frontal bone from his skull, with the nail head at the center of the disc. Slowly, we lifted this piece of bone up away from the surrounding skull, bringing the firmly embedded barbed nail with it. Although we could see a small jagged tear in the covering of the brain and a puncture wound on the surface of the brain itself, there was no blood oozing from the hole, and we considered ourselves lucky. ("Better lucky than good" is a favorite slogan among surgeons.)

Then, using large tools fit more for our patient's line of work, we clipped off the barbs and pounded the nail through the disc of skull, backward. After soaking the bone in an antibiotic solution, we neatly plated it back in place with miniature titanium plates and screws and sewed his scalp back together. Actually, rather than suture, we used surgical staples from a staple gun to close the final layer of his scalp, unaware, at the time, of the subtle irony in that move. Within less than twenty-four hours, the patient was on his way home, joking the entire length of the hall with the friend who nailed him in the head.

When I recounted this story to my family and friends after dinner one night, they all nagged me with the same question: "How could he be normal? This went into his brain." Finally, here's where the scientist in me gets to pontificate a bit, settling into a fast-paced question-answer session in the comfort of my own home with a captive audience. I am not just a mechanic, after all, and the brain is not just tofu.

How could he be normal? First of all, his brain function was considered normal based on our typical bedside examination, which is, admittedly, a bit coarse. His speech was fluent. He answered simple questions appropriately. I asked him to remember three objects over a five-minute time span, and he did. His pupils reacted when I flashed a light in his eyes and his eyes moved symmetrically. He had no drooping of his face. The strength in his arms and legs was normal and so was his sensation. His reflexes were fine. He was capable of rapid and coordinated hand movements. In other words, his five-minute neurological examination was perfectly satisfactory.

But the frontal lobes harbor quite sophisticated functions, more sophisticated than the relatively simple ones I tested. The frontal lobes make up the largest section of the brain and are the most recently evolved. Compare the forehead of an ape to the forehead of a human. One slopes, the other bulges. We can thank, or blame, our frontal lobes for much of what we consider to be our personality and intelligence. Damage to the frontal lobes can be subtle, including changes in insight, mood, and higher-level judgment ("executive function," in the professional lingo). I'm not going to detect such changes in the ER during my five-minute exam before he is whisked off to the CT scanner. I'm just the neurosurgeon here. We would need to consult a neuropsychologist to help us evaluate these more complex brain functions.

"So why didn't you send this poor guy for more sophisticated testing?" my dinner audience asks in a confused and mildly accusatory tone. Why did I simply proclaim him "fine" and send him on his way? I explain that the foreign object was a nail, not a jackhammer. A relatively minuscule portion of brain was violated. The large frontal lobes, in particular, can be quite forgiving, especially when only one side is involved. It's not unusual to see a frontal lobe tumor, for example, grow to impressive citrus fruit proportions before the patient even detects a problem. In fact, the patient often does not detect a problem at all. It is frequently a spouse or friend who insists on the doctor appointment, explaining: "He's just not right, but I don't know what it is."

There is a redundancy and resilience to certain brain functions. What is compromised in one portion can sometimes be compensated for in another. (A remarkable ability referred to as "plasticity.") Even if the brain doesn't compensate directly, the patient often can cope indirectly, without even realizing it. If a person develops minor difficulty with memory, for example, he may start to write more things down, thereby maintaining the otherwise seamless flow of his existence. There are limits, though, to the power of plasticity. Damage to a single frontal lobe is frequently well tolerated (the opposite frontal lobe can compensate to some degree), whereas damage to both sides is often irreversibly devastating.

Getting back to our carpenter, we were confident that the very narrow swath of injured brain in only one frontal lobe would be inconsequential. Even if a faint cognitive deficit could be identified with detailed and time-consuming neuropsychological testing, would the patient really care? Would he, or anyone else, even notice the problem? Would his life as carpenter, husband, or friend be affected? Doubtful. On a more cold-blooded and practical note, would the patient or the hospital be willing to pay for these tests? His insurance would certainly balk at the cost and question the necessity. Besides, given my confidence in the resilience of his frontal lobes, my biggest concern was not sluggish thought but sluggish carpentry. What if he gives up the automatic nail gun altogether?

And with this final thought, the mechanic in me reclaims the front seat, as the scientist heads again to the back.

It doesn't necessarily take a brain surgeon to think like a brain surgeon, especially when it comes to the fundamentals. Consider this elementary notion: there is a limited amount of room inside the skull. Another central truth, directly related to the first, is: the brain is not the only thing inside the skull. The brain, in fact, makes up about 80 percent of the intracranial contents. The other 20 percent is split about evenly in volume between blood and cerebrospinal fluid. Once you master these central tenets, a good deal of seemingly complex neurosurgical decision-making becomes transparent.

Neurosurgeons learn to care just as much about the 20 percent as they do about the 80 percent, even though everyone else is blinded by the mystique of that 80 percent. I get plenty of wide-eyed questions about the brain, but no one ever cares to ask about the cerebrospinal fluid, a real nonissue as far as the public is concerned. Neurosurgeons care about the cerebrospinal fluid because if there's too much of it, the brain could be rendered next to useless.

In learning to think like a neurosurgeon, you have to take these thoughts one step further: given the rigid, fixed-volume container of the skull, and the 80/10/10 balance of its contents, what can be done if the equation is disrupted? This tips us more into the realm of mechanic than scientist.

Consider what would happen if you were punched in the eye. The area around the eye becomes swollen and is free to swell as much as it needs to. Aside from the social and cosmetic downsides of having a puffy, swollen eyelid and face, the swelling itself is usually not dangerous. It's not constrained. It goes down after several days, and the skin and underlying soft tissues recover nicely.

A swollen brain is another matter. There's not much room for it to swell. Swelling within a fixed container leads to elevated pressure, and unchecked pressure can lead to a cascade of events--namely a last-ditch shifting of delicate intracranial contents--that can be fatal. So as neurosurgeons, we do whatever we can to maintain a normal pressure within the skull when things go awry, such as in a serious head injury.

Guest More than 1 year ago
For any woman that has ever considered being a surgeon, Another Day in the Frontal Lobe is an excellent introduction into the daily life of one of our nation¿s best. Katrina Firlik is a neurosurgeon, her job is to reconstruct damaged or malformed areas of the brain and spinal cord, remove tumors embedded in the brain tissue or bordering in cerebrospinal fluid, consult with anxious patients and their families about the treatment they are about to face, and teach aspiring undergraduates at the local university- all in a day¿s work. Personally, I have been debating as to what area in medicine I would like to devote myself to ever since I decided that I wanted to be a doctor in the fifth grade. Back when I was 10, all I knew was that I loved science and that I wanted to make a difference, but really had no idea as to what I would need to go through to make that dream come true. Luckily, reading Another Day in the Frontal Lobe has given me a much clearer idea of the road ahead Katrina Firlik¿s writing style is informative, educational, and personal. Although she is extremely intelligent, she does not write ¿over your head¿ nor does she water down explanations of important surgical procedures or testing methods to make brain surgery overly simple. Her unique way of explaining exactly what a specific test does in a detailed and thorough, yet comprehensible, manner makes the most complicated of practices fascinating. Firlik applies this same detailed style to her recounting of the educational process involved in becoming a neurosurgeon. The entire book is arranged in chronological order, beginning with her 4 years of undergraduate studies, moving through another four years of medical school, and ending with her year as chief resident after seven years of residency in neurosurgery. She incorporated the comical moments of her education, such as the ¿pimping¿ of interns in the post-operation council, with her frustrations- 3 AM phone call to return to the OR for an emergency operation after just leaving a double shift- to make her retelling of her 15-year venture come alive. When Firlik is applying to one of many residency programs, an interviewer gives her a powerful and haunting piece of advice, ¿Don¿t become a neurosurgeon unless there is absolutely nothing else you could ever see yourself doing.¿ This stunningly blunt council is both the cause for Firlik¿s affirmation of her decision to become a neurosurgeon as well as the catalyst for her favorite question when she feels close to a breaking point, ¿Why did I choose to be a neurosurgeon.¿ This is a renown question that many ask themselves in times of deep frustration when it appears that the hardest path possible was inevitably the one that was chosen. Although the question appears pessimistic, it is really the asking of it that reminds Firlik why she chose this demanding occupation in the first place- the challenge, the thrill, and the satisfaction of improving someone¿s life. Another Day in the Frontal Lobe has been my most realistic taste of what my potential future may be like. It will be another decade and a half of intense education after high school, a grueling climb marked with stress and tragedy to the top of medical hierarchy, and countless sleepless nights in which my choices make the difference between another¿s life and death. Despite all of this, I have learned from Firlik that with the challenge of being a surgeon comes the endless benefit of a lifetime of learning. Surgeons must constantly adapt to changes in technology and science itself, remain up-to-date on the latest finds in scientific journals, and continuously evolve their practice to meet the contemporary. Another Day in the Frontal Lobe demystifies the lengthy journey to becoming a surgeon and uniquely inspires pre-med hopefuls to never back down on a dream for fear of failing.

Katrina has done an excellent job telling an engaging story about her start in medicine to her current cases. She adds a bit of humor throughout, and makes sure to clearly explain any medical terms.
Guest More than 1 year ago
You will love this book if you are the type that is fascinated by the vivid surgeries shown on those medical channels on cable TV. Also, if you ever considered going to medical school, whether you chose that path or not, this is the book for you. It's an honest and sincere account of Katrina Firlik experiences throughout medical school. I think it will be particularly relevant for women who are considering this career path. Her next book should continue with her experiences with her medical practice but also include how she manages to balance career and family. Many young women need to hear about these issues now.

This book is filled with the drama of tragedy, learning to be with people in the midst of heartache and uncertainty, and pure excitement, as Ferlik learns her rare trade. Somehow Ferlik also infuses a great amount of humor into these tales of her internship, and this is honestly one of the funniest books I've ever read. Reading it for the second time now, the dry humor is more apparent. Along with other books about either neuroscience or the written experiences of those on the front lines of brain surgery or neurology, I rank this read as tops and give it an easy five stars.

I am a teenager who is very interested in majoring in biomedical engineering and minoring in neuroscience. I saw this book at my library and picked it up in a second. I read through the book really quickly, because it was so amazing. If you are interested in the brain at all, this book is really good. I actually took notes on the different diseases, tools, etc. I don't think there was anything bad about the book.
Hungry_Hippogriff More than 1 year ago
had really high hopes for this book. I truly enjoy the nitty, gritty stories of medicine and hoped this would really be an insider's look at neurosurgery. Alas, it was not. It was interesting and gave some great historical information about the development and advances of neurosurgery. The cases she presented were really interesting, but there weren't really many of them and she didn't really give much in the way of description as far as surgery goes. The explaination of the different diseases and afflictions of the brain was fascinating, however. It's not a bad read. In reflecting upon what she views as the arrogance of some of her collegues because they are in such a elite profession, she does come off as a bit arrogant and superior herself. We get it. You're awesome and things that laypersons wouldn't understand come as easily to her as breathing. The descriptions of other famous neurosurgeons, pioneers in the field, and their research and developments are interesting. I have to admit though, by the end chapter my eyes were glazing over a bit. I really, really wish the writing and presentation were better. This had great potential.

A book written by a neurosurgeon. While the author can be a bit arrogant, she has a passion for the human brain. She manages to pass that passion onto the reader.

Ultimate difficult job? Brain surgeon, right? Turns out it's not that least it doesn't seem all that hard according to Katrina Firlik in her memoir, Another Day in the Frontal Lobe. She's got some stories to tell. I won't give anything away, but you won't forget the man with the infection that moved from his face into his brain.

For a story of what it takes to perform neurosurgery - which is not just brain surgery - Katrina Firlik's memoir comes off as a breeze. But a deceptive breeze. At some point, you'll find yourself recounting anecdotes to friends and family on the performance tricks of drills, the differences between neurologists and neurosurgeons, why certain infamous film cannibals may have done the impossible and, of course, describing glioblastomas in terms of popcorn. These sprinklings of fact are effortless and incredibly engaging. Might I add that you'll feel the need to correct individuals on the 10% usage misnomer as well?Firlik does an amazing job of humanizing what can be a job that is easily dehumanizing every day. She addresses the issues of delivering bad news on a regular basis, addresses the trickier aspects of what medical technology can do vs. what may or may not be best for a patient and will drive home the point of seeing your doctor as soon as possible and wearing your seat belt in graphic fashion. At the same time, she doesn't seem quite clear on how she's able to do some of the things she does - why she maintained so much positivity, how she really felt about being the first woman in her neurosurgery program, or how she really maintained her commitment to a program so many others find too demanding. In some cases, her chapters started out down these paths, but seemed to veer off either because the thoughts never manifested or maybe because the answers just never came. Thankfully, the brain offers plenty of fascinating backup stories to make up for these small holes.

I liked it -- well written, authentic and consistent voice, part memoir part essay part science.
Hoker on LibraryThing More than 1 year ago
An enjoyable read, and a valuable one. My daughter is considering this profession as a career path and this book provided valuable insights into the profession. It also gave me a glimpse into what her future world may look like.

¿When I walked into the infant¿s hospital room for the first time the lights were off and the shades down, in the middle of the day. The pediatric neurology team was crowded around the crib. The senior neurologist was holding a flashlight up against the baby¿s head, and all the residents and medical students stared at the resulting spectacle: a round, pinkish, glowing orb. Because most of the skull was filled with fluid and not brain, and a baby¿s scalp and skull are normally relatively thin, the light was able to pass right through, lighting up the head in an eerie display.¿This is just one of the many stories Katrina Firlik relates in her new book, Another Day in the Frontal Lobe: A Brain Surgeon Exposes Life on the Inside. Firlik was the first woman to be accepted into the University of Pittsburgh Medical Center¿s neurosurgery residency program. This book tells of her training and eventual mastery of the mind.She is very humble throughout the book, explaining that her job isn¿t rocket science. She sees her roll as more of a mechanic, using her hands to relieve pressure on the brain, as a grease monkey might loosen a bolt. She states, ¿If you have an expanding blood clot in your brain, you want a skilled brain mechanic, and preferably a swift one. You don¿t care if your surgeon published a paper in Science or Nature.¿One could say her mantra throughout the book is ¿this is not rocket science,¿ but, hello, it is brain surgery. She reminds me of a certain person who can¿t accept compliments without devaluing herself. Hum?The book can be graphic at times; for instance, she tells about the removal of a flush, two-inch, carpentry nail. If you get a little woozy reading about maggots and pus, please reach for something else. If not, you will find Firlik humorous at times. She may even settle a bet about the movie Hannibal for you.The title, and the fact that Firlik is one of only five percent of women serving in the neurosurgery field, might lead a reader to think the book encompasses male incompetent situations, but this is not the case. She never dishes the dirt of others, but rather tells of her own mistakes, which makes for a refreshing take that will win male and female readers alike.
