Question 1

How would Liepmann account for apraxia of the left hand only? (Hint: a diagram may prove useful.)

Accepted Answer

When given a verbal command, the left-hemisphere language regions would comprehend the command and then need to "send" the information to the right-hemisphere motor region. If the corpus callosum were severed, this message would not be sent to the right hemisphere and subsequently would not be able to initiate the motor behavior.

Question 2

Discuss the ability of a blindfolded commissurotomy patient to verbally identify three - dimensional objects placed into either the left or right hand.

Accepted Answer

In this situation, the patient would be able to identify objects in the right hand verbally but not those held in the left hand.
