What anatomical landmark of the
cerebral cortex separates primary
motor areas from somatosensory
areas?
(a) Make a rough drawing of the lateral aspect of the left cerebral hemisphere. (b) You may be thinking, “But I just can’t draw!” So, name the hemisphere involved with most people’s ability to draw. (c) On your drawing, locate the following areas and provide the major function of each: primary motor cortex, premotor cortex, somatosensory association cortex, primary somatosensory cortex, visual and auditory areas, prefrontal cortex, Wernicke’sand Broca’s areas.
Which part of the cerebral cortex contains the primary motor cortex?
a) occipital love
b) prefrontal lobe
