TBI Physiology of the Brain 3

Question 1

Damage to the prefrontal cortex most characteristically produces which problem?

Accepted Answer

Impaired executive function and personality change

Answer

The prefrontal cortex governs planning, judgment and behavior regulation, so injury causes executive and personality changes.

Question 2

Injury to Broca's area typically results in which deficit?

Accepted Answer

Expressive aphasia with halting speech and intact comprehension

Answer

Broca's area in the left inferior frontal lobe controls speech production, and damage causes non-fluent expressive aphasia.

Question 3

Which structure is most critical for forming new declarative memories?

Answer

The occipital lobe at the back of the brain processes visual information.

Question 5

Which brain region is primarily responsible for coordination of movement and balance?
