Cortex

Question 1

Where is the pyamidal cell layer? Is it deep, or superficial?

Answer 1

V, deep.

Question 2

Where are supcortical efferents located?

Answer 2

Internal capsule.

Question 3

What connects Broca’s and Wernickes areas?

Answer 3

Association fibers.

Question 4

What are the primary corticies?

Answer 4

Motor (frontal), somatosensory (pariatal), visual (occipital), auditory (temporal.

Question 5

Motor and somatosensory association areas surround the primary motor and somatosensory areas. Are they heteromodal?

Answer 5

No, they’re unimodal. Heteromodal areas surround the unimodal association areas.

Question 6

Number the 4 primary corticies in the brain.

Answer 6

MOTOR = 4
Somatosensory = 3,1,2
Visual = 17
Auditory = 42, 22

Question 7

Number the motor and somato association areas.

Answer 7

Motor = 6 (premotor)
Somato = 5, 7

Question 8

T/F: Travelling with the “where” (dorsal) pathway, number the areas.

Answer 8

17, 18, 19.

Question 9

What are does motor planning and sensory integration occur? Hint: this is the “what” pathway for recognition.

Answer 9

39, 40, where the arrow for the ventral stream runs.

Question 10

Are areas 39, 40 (sensory integration) uni or heteromodal?

Answer 10

Heteromodal.

Question 11

What area is the frontal eye field in?

Answer 11

8, some 6.

Question 12

The arcuate fasiculus connects Broca (45, 44) and Wernicke’s (22) areas. What area does it run though?

Answer 12

Area 4, Motor cortex!
