Answer 3

Responsible for arousal (unconscious to conscious), and habituation (filtration of incoming information). Part of the brain stem

Question 4

Sense that is most strongly affected by damage to the reticular formation

Answer 4

Smell

Question 5

Cerebellum

Answer 5

Responsible for muscle movement, muscle memory, coordination, learning, and memory formation. Has 50% of your brain cells.

Question 6

Thalamus

Answer 6

Answer 7

No

Question 8

Pituitary gland

Answer 8

Regulates release of hormones. Part of the midbrain

Question 9

Hypothalamus

Answer 9

Regulates primitive appetites and drives. Has role in motivation and body regulation. Part of the midbrain

Question 10

Hippocampus

Answer 10

Involved in forming and retrieving long-term memories. Part of the midbrain

Question 11

Amygdala

Answer 11

Organizes motivational and emotional responses. Part of the midbrain

Question 12

Hippocampus vs Amygdala

Answer 12

Hippocampus deals with facts, amygdala deals with how to interpret it

Question 13

Frontal Lobe

Answer 13

“CEO” of the body. Responsible for executive functions

Question 14

Executive Functions

Answer 14

Inhibition, evaluating consequences, working memory, thinking about the future

Question 15

How does Broca’s Area damage affect you?

Answer 17

Unable to speak (or sign). You can still write

Question 18

How does Wernicke’s Area damage affect you?

Answer 18

You can speak what you think are comprehensive sentences, but it will be complete gibberish

Answer 19

Area of the cortex responsible for speech formation. In temporal lobe.

Question 20

Auditory Cortex

Answer 20

Responsible for hearing. In temporal lobe
