Answer 6

True

Question 7

Damage to any part of the striate cortex can lead to _______ _____-, impacting a person’s ability to see and process visual stimuli.

Answer 7

cortical blindness

Question 8

It lies between the occipital lobe and the central sulcus, which is one of the deepest grooves on the surface of the cortex.

Answer 8

parietal lobe

Question 9

The primary somatosensory cortex or the __________ gyrus is responsible for processing touch sensations and muscle-stretch receptors and joint receptors.
It allows us to perceive and interpret sensations.

Answer 9

postcentral

Question 10

The parietal lobe handles the positions of our eyes, head, and body too and passes it on to brain areas that control movement.

The frontal lobe contains two important regions:
- or primary motor cortex
-

Answer 17

the precentral gyrus
