[Structure and electrophysiological properties of bursting neurosecretory cells in a peripheral sensory ganglion of the pond snail Lymnaea stagnalis].
A group of peripheral neurosecretory oscillating neurons belonging to the type of parabolic bursters, were identified in the osphradium (peripheral putative chemosensory organ) of the pond snail Lymnaea stagnalis. The cells are unipolar, their process ramifies and terminates in the nerve. Applications of 5-HT caused long-lasting bursts with significantly increasing duration and frequency of spikes. GABA and FMRFamide inhibited the activity of these cells.
