Experiments were performed on rats using retrograde axonal transport of horseradish peroxidase with the aim of identifying cells in the individual structures of the central nucleus of the amygdaloid body (CNAB) innervating the paraventricular nucleus of the hypothalamus. Labeled cells were seen in the ipsilateral CNAB throughout its rostrocaudal extent. The largest number of labeled neurons was seen in the middle third of the nucleus in the area corresponding to the intermediate subnucleus of the CNAB. Occasional cells were located in the medial and lateral subnuclei of the CNAB. Labeled neurons in the intermediate subnucleus were oval cells or cells of indeterminate shape.
