medical health brain and nervous system disordersWhat are the four cerebral hemispheres?
Keeping this in consideration, what are the two cerebral hemispheres?
The vertebrate cerebrum (brain) is formed by two cerebral hemispheres that are separated by a groove, the longitudinal fissure. The brain can thus be described as being divided into left and right cerebral hemispheres.
Keeping this in consideration, what do the cerebral hemispheres do?
The cerebral hemispheres are the highest level of the Central Nervous System. They are like two mushroom caps bulging of the left and right front end of the brain stem, as shown in Figure 1 at the right. They control the activity of the lower levels, directing the overall plan and direction of behavior.
The right cerebral hemisphere controls movement of the left side of the body. Depending on the severity, a stroke affecting the right cerebral hemisphere may result in functional loss or motor skill impairment of the left side of the body.
