The basolateral amygdaloid projections to the neocortex in the cat.
Retrogradely labeled cells have been found in the ipsilateral basolateral nucleus of the amygdala (BL) following injections of horseradish peroxidase (HRP) in various neocortical areas in the cat. The number of labeled neurons was small in the majority of the cases; however the amygdaloid projections to the prefrontal, anterior cingulate, insular and posterior sylvian cortices appeared heavier. HRP injections in the parietal associative and visual areas did not result in labeled cells in the amygdala. The present data suggest that the cortical projections arising from BL are more widely distributed than previously reported.
