Control of Brain micrograph cortical layers

In the control brain micrograph below (Panels C and A), the left image shows different cortical layers in different colors. The right image shows “barrels” formed by thalamocortical axons in pink.   Describe your observations of panels D and B (with the same colors) below, from the reeler mutant brain. (Hint: when referring to a specific panel – put the letter in your answer)   Observations of left image (Panel D) Observations of right image (Panel B)   Overall conclusion:
