Full Description
This monograph summarizes the results of the authors' own in- vestigations as well as relevant literature data about the mechanism of synaptic transmission in sensory hair cells of the acousticolater- al system. It deals mainly with primary processes in hair cells. Ad- ditionally, data on the properties and selectivity of various ionic channels are presented, with data concerning the mechanism of release of the neurotransmitter from the hair cell and the proper- ties of postsynaptic responses of afferent fibres. The role of ex- citatory amino acids in synaptic transmission is analyzed. This book gives a comprehensive overview of current research on synaptic transmission in sensory hair cells, which should be valuable to both those in the field and neuroscientists of various disciplines.
