Question 3

What is a sulcus/ sulci?

Small grooves that surrounds a gyrus (the part that goes inward, a valley)

Question 4

Answer 4

The more folds the more surface area which makes more connections (allows more space for more neurons)

Question 5

Answer 5

Large grooves that separate lobes (the central sulcus is actually a fissure)

Question 6

Answer 6

Language processing (on the left side)

Question 7

Main sense associated with the occipital lobe?

Answer 7

vision

Question 8

Main sense associated with the Parietal lobe?

Answer 8

sensory

Question 9

Main sense associated with the frontal lobe?

Answer 9

motor

Question 10

what is the difference between a primary cortex and an association cortex?

Answer 10

primary- basic motor or sensory function

Association- more complex processing and functions (planning)

Question 11
