anterior thalamic nucleus

The most rostral of the thalamic nuclei. The anterior thalamic nucleus is the only thalamic nucleus that is directly part of the limbic circuitry. This nucleus receives axons from the mammillary body via the mammillothalamic tract, from the hippocampus via the fornix, and from cholinergic nuclei in the basal forebrain. The anterior thalamic nucleus sends axons to medial cerebral cortices: the cingulate gyrus, the anterior limbic area, and the parahippocampal gyrus.
