Neuronal Acetylcholine Receptors

Among the different types of receptors for neurotransmitters, nicotinic acetyl­ choline receptors were the first to be studied systematically; at present they are very well characterized. This is due to the discovery of two very convenient objects that are endowed with nicotinic acetylcholine receptors - the skeletal muscle and the electric organ. The large size of skeletal muscle fibers, which simplifies the intracellular recording of transmembrane potentials and currents, played a crucial...
