Morphological evidence for synaptic junctions between substance P-containing neurons in the arcuate nucleus of the
Neuroscience Letters
|April 20, 1984
Abstract:
The presence of synaptic junctions between substance P-containing neurons (SP neurons) was shown in the hypothalamic arcuate nucleus of rats by pre-embedding electron microscopic immunohistochemistry. The immunoreactive perikarya were synapsed by immunoreactive fiber terminals as well as immunonegative fiber terminals. The functional implication of the synapses between SP neurons is discussed in relation to autoregulatory mechanisms of the neurons.
