A. the pre-central gyrus; the post-central gyrus
B. S1 of the parietal cortex; the VPC of the thalamus
C. the prefrontal cortex; the VPC of the thalamus
D. S1 of the parietal cortex; the LGN of the thalamus
E. the frontal cortex; the parietal cortex
2. Area 3b of the post-central gyrus (select any/all answers that apply):
primarily receives ascending information about proprioception.
projects heavily to field 3a of the post-central gyrus.
projects heavily to field 2 of the post-central gyrus.
is heavily innervated by projections from the VPC of the thalamus.
contains a motor map of the body.

Explanation / Answer
1) Somatotopic maps are the spatial patterns in the functional organization of neuronal responses in the mammalian primary somatosensory cortex. This somatotopic maps are present in S1 of the parietal cortex and VPC of thalamus (option B).
