Electrophysiological characterization of reciprocal connections between the parabrachial nucleus and the area postrema in the rat
S Papas, AV Ferguson - Brain research bulletin, 1990 - Elsevier
Neuroanatomical studies have demonstrated reciprocal connections between the
parabrachial nucleus (PBN) and both the area postrema (AP) and the nucleus tractus
solitarius (NTS). To functionally characterize these projections, antidromic identification of
AP and NTS neurons projecting to the PBN was attempted. Orthodromic influences on these
cells, resulting from PBN stimulation, were also examined. Four percent of AP neurons
tested (n= 74) were antidromically identified as projecting to the PBN [latency (L)= 26±4 …
