A few retrogradely labeled cells were found in the dorsal and ventral thalamus, in which scattered marked neurons were observed consistently in the rostral part of the paraventricular nucleus (Fig. 3E), parataenial nucleus (Fig. 3E), peripeduncular nucleus (Fig. 3M), and rostral pole of the zona incerta (Fig. 3H–J).
