-
refers to fiber pathways in the internal capsule and other parts of the cerebral white matter that connect the nuclear groups of the thalamus with the cerebral cortex ( Carpenter-1983 ).
They include the anterior thalamic radiations, the posterior thalamic radiations, the superior thalamic radiations and the inferior thalamic radiations. They are not readily distinguished in myelin-stained histological cross-sections. For a detailed discussion of semantic differences in the use of terms relating to the thalamic peduncles and thalamic radiations see Anthoney-1994.
