Both limbs contain cortical afferents. The well known sensory radiations, from VPM and VPL, are located in the posterior limb. The anterior limb also has afferents from thalamic nuclei that have connections with the cerebellum and basal ganglia. This sagittal section allows you to see both limbs. The frontal pole is to the left.
