Only one significant difference was found, and in the visceral ganglion, with the females having a higher median score for dopamine when compared with males and undifferentiated specimens.
Fine-structure of the neurons in the mid-dorsal lobes of the visceral ganglion of the Lamellibranch mollusc Scrobicularia plana (da Costa).
Serotonergic neurotransmission in the bivalve Venus verrucosa (Veneridae): a neurochemical and immunohistochemical study of the visceral ganglion and gonads.
In the visceral ganglion of the adult snails, a single GLU-LIR neuron occurred in the center of the ganglion (Fig.
Three individual medium-sized neurons were also added, two of them in the visceral ganglion and one in the right parietal ganglion (Fig.
The visceral ganglion had the least numbers of GABA-ir neurons compared with the other 2 ganglia.
Gamma-aminobutyric acid-ir neurons were densely scattered in the cortex region of the dorsolateral and dorsomedial parts of the visceral ganglion of both females and males (Fig.
The first is serial electron microscopy (EM), as part of a dedicated study of the visceral ganglion , and the second is the transient transfection of neural plate progeny with green fluorescent protein (GFP) , to visualize the soma and its neurites of individual neurons in whole-mounted larvae of C.
The motor neurons have been widely presumed to lie in the visceral ganglion, the middle division of the CNS, between the rostral swelling of the sensory vesicle and the caudal nerve cord [8, 14].
Furthermore, the NS cells of the visceral ganglion are of NSg types I and III.
The nervous system of the giant African snail Achatina fulica is composed of 13 ganglia: a pair of buccal ganglia, a pair of cerebral ganglia, a pair of tentacular ganglia, and a subesophageal mass containing 2 pleural ganglia, 2 parietal ganglia, 2 pedal ganglia, and a single visceral ganglion (Kruatrachue et al.
The 5-HT cells were most numerous in the cerebral (~70/2,300 cells per section), and the pleuropedal ganglia (~120/2,700 cells per section), whereas they were least numerous in the visceral ganglion
(~50/400 cells per section).
