Question 7

A corpus callosotomy is a procedure in which the corpus callosum is cut to decrease the severity of certain types of seizures. After the procedure, some patients have extreme difficulty performing actions related to the non-dominant hemisphere, like using their non-dominant hand. What might be the basis for this side effect?

Accepted Answer

A)  The corpus callosum contains neurons that cross from one hemisphere to the other. Cutting the structure prevents the dominant hemisphere from controlling motor function in the non-dominant hemisphere.
B)  The corpus callosum handles some somatic motor neurons. Cutting the structure will stop motor function signals from one hemisphere.
C)  The corpus callosum separates the two hemispheres. Cutting the structure allows the dominant hemisphere to interfere with the motor control within the non-dominant hemisphere.
D)  The corpus callosum is the seat of control for fine motor function and positioning. Cutting the structure will prevent the onset of seizures, but also hinders fine motor function and causes confusion about where a body part is at any given time.E) A) and B)
F) B) and C)
