Cerebral-abdominal interganglionic coordinating neurons in Aplysia.
Three cerebral-abdominal interneurons (CAIs), CC2, CC3, and CC7, were identified in the cerebral ganglion C cluster. The cells send their axons to the abdominal ganglion via the pleural-abdominal connective. CC2 and CC3 are bilaterally symmetrical cells, whereas CC7 is a unilateral cell. CC3 is immunopositive for serotonin and may be the same cell (CB-1) previously described as located in the B...
متن کاملlnterganglionic Axonal Transport of Neuropeptides in Ap/ysia
The transport of neuropeptides between central ganglia was studied in Aplysia. Peptide transport was determined by incubating ganglia with %-methionine and measuring the appearance of labeled peptides in connected ganglia. Selected interganglionic connectives were left intact and passed through a diffusion barrier separating the ganglia. Labeled peptides transported between ganglia included FMR...
متن کاملFast axonal transport of modulatory neuropeptides from central ganglia to components of the feeding system in Aplysia.
The transport of neuropeptides from central ganglia to components of the feeding system was studied in Aplysia. Peptide transport was determined by incubating buccal or cerebral ganglia with 35S-methionine and measuring the appearance of labeled peptides by high-pressure liquid chromatography (HPLC) of extracts of target tissues. Selected nerves were left intact and passed through a Vaseline di...
متن کاملHead waving in Aplysia californica. III. Interganglionic pathways underlying the coordination and control of searching movements.
The central nervous system of the sea hare Aplysia californica is divided into four pairs of ganglia and a fused abdominal ganglion. Work in several laboratories has established that the neural circuitry for producing locomotor rhythms is contained within the pair of pedal ganglia. The cerebropedal connective carries command-like information from the cerebral ganglia, and neurones projecting in...
متن کاملAxonal transport of [3H]serotonin in an identified neuron of Aplysia californica
A population of characteristic ellipsoidal dense-core vesicles was identified in axons of the giant cerebral neuron of the mollusc Aplysia. We injected [3H]serotonin into the cell body of this identified serotonergic neuron in the isolated central nervous system in order to study the subcellular components associated with the neurotransmitter. Subcellular fractionation by differential centrifug...
