By means of the silver impregnation method for degenration nerve fibers and retrograde fluorescent tracer methods, following results were obtained on the connection of anterior thalamic nuclei in the albino rat.1.The anterodorsal thalamic nucleus projects to the ventral part of the posterior cingulate cortex as well as to the ventromedial part of the retrosplenial cortex.The anteroventral thalamic nucleusprojects to the dorsal part of the anterior cingulate, whole area of the posterior cingulate and the anterior part of the retrosplenial cortex. While the anteromedial nucleus projects only to the anterior and posterior cingulate cortices.2.As for the projection of the anterior thalamic nuclei to the diencephalon, there are fibers projectiong to the bilaterallateral habenular nuclei, ipsilateral dorsomedial and parafascicular nuclei passing through the stria medullaris thalami.3.Anterior thalamic nuclei send their fibers to the lateral preoptic area and the lateral hypoothalamic area of the hypothalamus through the stria medullaris thalami and the fasciculus medialis prosencephali (medial forebrain bundle).4.No thalamomamillary fibers are thought to exist in the mamillothalamic tract. and no interthalamic commissural fibers exist between the bilateral anterior thalami nuclear groups in the albino rat.
