anterior nuclei of thalamus

(redirected from Anterior thalamic nuclei)

an·te·ri·or nu·cle·i of thal·a·mus

[TA]
collective term for three groups of nerve cells that together form the anterior thalamic tubercle: the anteroventral nucleus [TA], a relatively large nucleus; the anteromedial nucleus [TA]; and the anterodorsal nucleus [TA], a small (but large-celled) nucleus. These nuclei receive the mammillothalamic tract from the mammillary body, and additional afferents by way of the fornix; they project collectively to the cortex of the cingulate and parahippocampal gyrus.
Synonym(s): nuclei anteriores thalami [TA]
