Abstract:
Direct projections from the globus pallidus (GP) to the lateral amygdaloid nucleus (A1) were found in the cat by the anterograde and retrograde tracing methods. Pallido-amygdaloid fibers originated mainly from the caudal half of the GP and distributed throughout the entire extent of the A1; most densely in the lateral part of the A1. Choline acetyltransferase immunohistochemistry in combination with retrograde fluorescent tracing indicated that most pallido-amygdaloid neurons were cholinergic.
