Projections of the Nucleus of the Solitary Tract and the Parabrachial Nuc leus to the Central Nucleus of the Amygdala: An anatomical observation with the technique of horseradish peroxidase tracing in the rat
Objective To evaluate the important role of the nu cl eus of the solitary tract (NST), the parabrachial nucleus (PBN) and the central nucleus of the amygdala (CNA) in the visceral and cardiovascular regulation, pro jections of NST, PBN to CNA in the rat was investigated.Methods The morphology of neurons in NST and PBN, projected to CNA wa s studied by the technique of retrograde horseradish peroxidase (HRP) tracing. Results A large number of HRP labeled medium-sized neurons, includin g round with multi...
