Functional areas of the Cerebral Cortex

Question 1

Primary motor cortex

Answer 1

This gyrus immediately in front of the central sulcus is literally “hardwired” to the muscles of the body. Stimulation of specific locations on this gyrus will cause specific muscles to contract.

Question 2

Motot association area

Answer 2

The area plans movement and ensures muscle contractions are coordinated and smooth.

Question 3

Prefrontal cortex

Answer 3

This area is responsible for the “executive functions” of the brain. This includes making decisions, determining beliefs, executing judgment, and many other traits that create a person’s character and personality.

Question 4

Broca’s area

Answer 4

This area is only located on the left hemisphere next to the region for higher mental function and motor movement. It is for speaking and writing language.

Question 5

Primary auditory cortex

Answer 5

This area receives direct impulses from the ear.

Question 6

Auditory association area

Answer 6

This area interprets sound impulses and gives them meaning.

Question 7

Primary somatosensory cortex

Answer 7

This gyrus immediately behind the central sulcus is also literally “hardwired” to the touch receptors of the body (soma).
