This volume on the processes of transformation of mechanical stimuli into electrical activity in various mechanoreceptors comprises the authors investigations as well as relevant literature data. It deals mainly with initial electrical processes from stimulus of the mechanoreceptor to receptor potential. For the first time the connection between passive and active ion transport and the generation of electrical potentials is considered in detail. Furthermore, data on the properties and selectivity of different types of mechanosensitive ion channels, as well as results of morphological...

The acousticolateral system plays an important role in the biological activity of vertebrates. It includes the organ of Corty, the vestibular and otolith apparatus, lateral-line organs and electroreceptors. Throughout the acousticolateral system, the sensory receptors are hair cells. Provided here is a comprehensive overview of current research on synaptic transmission in sensory hair cells. Morphological characteristics are presented and data on the properties and selectivity of various ionic channels are given. The mechanisms of neurotransmiter release from hair cells and the postsynaptic...

Sympathetic afferent fibers originate from a visceral organ, course in the thoracolumbar rami communicantes, have cell bodies located in dorsal root ganglia, and terminate in the gray matter of the spinal cord. Sympathetic afferent fibers from the heart transmit information about noxious stimuli associated with myocardial ischemia, i. e. angina pectoris. Previous reviews have described the characteristics of cardiovascular sympathetic afferent fibers (Bishop et al. 1983; Malliani 1982). This review summarizes that work and focuses on the neural mechanisms underlying the complexities of angina...
