Abstract

The aim of this study was to identify, using retrograde axonal transport of horseradish peroxidase in rats, the cells, within distinct divisions of the amygdala central nucleus, innervating hypothalamic paraventricular nucleus area. The labeled cells were found in the ipsilateral amygdala central nucleus in the whole of its rostro-caudal extension. The maximal number of labeled neurons was detected in the middle third of the nucleus, corresponding to the intermediate subnucleus of the central nucleus. Single cells were located in the medial and the lateral subnuclei of the amygdala central nucleus. Labeled neurons of the intermediate subnucleus were represented by the oval cells or the cells of an indefinite form.
