lateral sulcus

Question 4

What are the functions of the frontal lobe?

Answer 4

precentrral gyrus (motor strip)- which is responsible for motor control
brocca’a area- located in the left frontal lobe and is involved in speech motor planning, controlling muscles required for speech

The function of the parietal lobe is?

Answer 8

the precentral gyrus is located in this lobe and is responsible for processesing information
different parts of the gyrus process information in different parts of the body (somatosensory cortex)

What is the superior temporal gyrus?

Answer 10

it contains the primary auditory cortex

Question 11

What does the heschl’s gyrus process?

Answer 11

it is part of the auditory cortex, it processes sound

What is the Wernick’s area involved in?

Answer 12

language comprehension

Question 13

What is the primary function of the occipital lobe?

Answer 13

it is responsible for recieving visual stimulation

Question 14

T/F the occipital lobe is involved in higher-level visual processing, like interpreting shapes, colors, and motion

Answer 14

true

Question 15

Where can you find the insula (insula lobe/cortex)?

Answer 15

it is revealed by moving the temporal lobe aside
located deep in the lateral sulcus

Question 16

what is the primary role of the insula?

Answer 16

plays roles in motor speech planning and socio-emotional processing (related to emotions, empathy, and understanding social situations)

Question 17

What is gray matter?

Answer 17

contains neuron cell bodies and it processes information in the brain
