title: [Study of the connections of supposed diencephalic connections of the limbic system of the lizard using the technic of axonal transport of horseradish peroxidase].
abstract: Connections of the anterior thalamic (n. dorsolateralis anterior, n. dorsomedialis) and habenular nuclei in lizards Ophisaurus apodus were studied by means of HRP administration into these nuclei. It was shown that all nuclei have overlapping locations of afferent sources (basotelencephalic structures, nuclei of anterior and hippocampal commissures, lateral area of the hypothalamus, superior raphe nucleus) and overlapping projectional zones (mammillary complex, ventral tegmental area). Besides common connections, specific ones for separate nuclei were revealed: for n. dorsolateralis anterior-reciprocal connection with dorsolateral hypothalamic nucleus, for habenular nuclei-projection to the interpeduncular nucleus, for n. dorsomedialis-projection to the dorsal hypothalamic area. No mammillary afferents were found for the anterior thalamic nuclei. All the nuclei studied are considered as diencephalic relay links of pathways which can be compared with dorsal (for habenular nuclei) and ventral (for anterior thalamic nuclei) pathways of the limbic system in mammals.
