Q

What is the difference between the right and left Broca’s areas?

A

The dominant hemisphere (usually the left side) is the speech planning area. The opposite side is involved in non-verbal communication like emotion, gesture, tone of voice, etc.

16
Q

What disorder is caused by lesions of motor planning areas?

A

Q

Define apraxia generally

A

A disorder of sensory integration interfering with the ability to plan and perform skilled and complex movements

20
Q

A

Facial apraxia

22
Q
