The rapid [Cl.sup.-] conductance increase elicited by GABA in the Aplysia visceral ganglion was found to share several characteristics with responses elicited by acetylcholine (Yarowsky and Carpenter, 1978a).
In Lymnaea stagnalis, a broader distribution of GABAli neurons was reported, including cells in the right parietal and visceral ganglion (Hatakeyama and Ito, 2000).
From each ganglion emerges the anterior pallial nerve (APN) toward the anterior region of the mantle, ramifying by all the edge of this and later joining with the posterior pallial nerve PPN (coming from the visceral ganglion) to form circumpallial nerves (CP).
Meanwhile, the visceral ganglion controls the cardiomodulation (Kodirov, 2011) and movement of the valves, mantle, siphons and gills in mollusks (Bayne).
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).
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.
In the visceral ganglion
of the adult snails, a single GLU-LIR neuron occurred in the center of the ganglion (Fig.
The nervous system of the female spotted Babylon, Babylonia areolata Link 1807, consists of left and right pairs of buccal ganglia, pedal ganglia, cerebral ganglia, pleural ganglia, and parietal ganglia, and a single left-side visceral ganglion
. Each ganglion has an outer cortex and an inner medulla.
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 5-HT immunoreactive cells were concentrated in the upper half of the medial edge of the cerebral ganglion, the edge of ventral and dorsal horns of the pleuropedal ganglion, and the fight latero-ventral edge of the visceral ganglion
; whereas the FMRF-amide immunoreactive neurons were concentrated in the dorsal and ventral edges of the cerebral ganglion, the edge of dorsal horn and the dorsal edge of the body of the pleuropedal ganglion, and the left latero-ventral and latero-dorsal edge of the visceral ganglion
