inferior thalamic peduncle

(redirected from radiatio inferior thalami)

in·fe·ri·or tha·lam·ic pe·dun·cle

a large fiber bundle emerging from the anterior part of the thalamus in the anterior and rostal direction, in part joining the medial fibers of the internal capsule, and in part curving laterally around the medial margin of the capsule into the innominate substance. Many of its fibers establish a reciprocal connection of the mediodorsal nucleus of the thalamus with the orbital gyri of the frontal lobe, but numerous other fibers constitute a conduction system from the amygdala and olfactory cortex to the mediodorsal nucleus.

(in-fēr'ē-ŏr thă-lam'ik pĕ-dŭngk'ĕl)
A large fiber bundle emerging from the anterior part of the thalamus in the ventral direction, in part joining the medial fibers of the internal capsule, in other part curving laterally around the medial margin of the capsule into the innominate substance. Many of its fibers establish a reciprocal connection of the mediodorsal nucleus of the thalamus with the orbital gyri of the frontal lobe, but numerous other fibers constitute a conduction system from the amygdala and olfactory cortex to the mediodorsal nucleus.

inferior thalamic peduncle

An axon tract running dorsally into the dorsomedial nucleus of the thalamus from the amygdala, the temporal cortex, and the substantia innominata.
