Question
Chapter 8, Problem 3RA
Summary Introduction
To determine:
The true statement about basal nuclei.
Introduction:
Basal nuclei are masses of grey matter. The most vital part of basal nuclei is corpus striatum that is comprised of numerous nuclei. In the brains of the vertebrate, the basal nuclei are located on the basal region of the forebrain and the upper region of the midbrain.
