Overview
For women, understanding how the brain works during the key stages of life - in utero, childhood, puberty and adolescence, pregnancy and motherhood, menopause and old age - is essential to their health. Dr Sarah McKay is a neuroscientist who knows everything worth knowing about women's brains, and shares it in this fascinating, essential book.
This is not a book about the differences between male and female brains, nor a book using neuroscience to explain gender-specific behaviours, the 'battle of the sexes' or 'Mars-Venus' stereotypes. This is a book about what happens inside the brains and bodies of women as they move through the phases of life, and the unique - and often misunderstood - effects of female biology and hormones.
Dr McKay give insights into brain development during infancy, childhood and the teenage years (including the onset of puberty) and also takes a look at mental health as well as the ageing brain. The book weaves together findings from the research lab, case studies and interviews with neuroscientists and other researchers working in the disciplines of neuroendocrinology, brain development, brain health and ageing.
This comprehensive guide explores the brain during significant life stages, including:
In utero
Childhood
Puberty
The Menstrual Cycle
The Teenage Brain
Depression and Anxiety
Pregnancy and Motherhood
Menopause
The Ageing Brain

About the Author
Dr Sarah McKay is a neuroscientist and science communicator who specialises in translating brain science research into simple, actionable strategies for peak performance, creativity, women's health and wellbeing. Her previous book, The Women's Brain Book: The Neuroscience of Health, Hormones and Happiness, explores the female lifespan through the lens of neurobiology.
Sarah grew up in New Zealand and completed her undergraduate degree in neuroscience at Otago University before heading to Oxford University for her MSc and PhD training. She sums up her doctoral thesis with the words, 'Nature, Nurture or Neuroplasticity'. Moving again, this time to Sydney, Australia, she completed five years of postdoctoral research in brain plasticity and spinal injury research before hanging up her lab coat to pursue a career in science communications. Sarah is the director of Think Brain, which offers a suite of professional development training programs in applied neuroscience and brain health.
Sarah has been published extensively for public, academic and professional audiences. She's been quoted in the Wall Street Journal, The Guardian, Sydney Morning Herald, The Age and Body & Soul. And she can be seen and heard 'explaining the brain' on SBS's Insight, ABC Radio National, Mamamia, NZ Radio National, ABC's Catalyst, and on stage at Business Chicks, Canberra Writers' Festival and Happiness & Its Causes.
Sarah and her Irish husband have settled on Sydney's Northern Beaches, where they are bringing up two surfer dudes and a cocker spaniel. Typically you'll find them in the ocean, either sailing, snorkelling or swimming.
