title: Distribution of serotonin-like immunoreactive neurons in the slug Limax valentianus.
abstract: Immunohistochemical techniques were used to study the distribution of serotonin-containing neurons in the nervous system of the slug Limax valentianus. Approximately 350 serotonin-like immunoreactive cell bodies were found in the central nervous system. These were located in the cerebral, pedal, visceral and right parietal ganglia. Most serotonin-like immunoreactive neurons had small cell bodies, which were aggregated into discrete clusters. A pair of previously identified metacerebral giant cells were found on the anterior side of the cerebral ganglion, and two additional pairs of uniquely identifiable, serotonin-like immunoreactive cells were found on the posterior side of the cerebral ganglion. The whole-mount maps of these stained neurons will be useful in further physiological and biochemical studies of olfactory learning at the cellular level in Limax valentianus.
