title: [Morphologic characteristics and responses of the neurons of the right parietal ganglion in Lymnaea stagnalis to stimulation of the sensory structures].
abstract: Intracellular recordings have been made of the responses of 22 neurons of the central part of the dorsal surface of the right parietal ganglion of the snail Lymnaea stagnalis to adequate stimulation of chemo-, photo- and mechanoreceptor cells of the mantle and head skin including tentacles and lips. It was shown that the main bulk of the neurons investigated has broad receptive fields in the body wall and mantle, being able to respond to all types of the applied stimuli. Alongside, single neurons were revealed which receive single-mode input, either a mechanosensory or chemosensory one. Morphological studies indicate that the neurons are unipolar and have usually one, sometimes several projections. They differ in the pattern of branching as well as in the projections to peripheral nerves. However, almost all of them have vast dendritic regions in the central nervous system including central sensory nucleus of the right parietal ganglion.
