Brain

Question 1

Brainstem (aka Hindbrain)

Answer 1

keeps us alive. 3 components: medulla, pons, reticular formation

Question 2

Medulla

Answer 2

part of brainstem; controls breathing/heart rate, help swallow/digest

Question 3

Pons

Answer 3

part of brainstem; bridge b/t cerebellums

Question 4

Reticular Formation

Answer 4

part of brainstem; neural network; arousal/alertness (*sleep cycle)

Question 5

Cerebellum

Answer 5

(2) coordination and balance (first to be affected by alcohol)

Question 6

Thalamus

Answer 6

takes in info and organizes/decides where in brain it should go

Question 7

Limbic System

Answer 7

pleasure/emotion center.

3 parts: amygdala, hippocampus, hypothalamus

Question 8

Amygdala

Answer 8

processes negative emotions

Question 9

Hippocampus

Answer 9

processes everyday memories

Question 10

Hypothalamus

Answer 10

homeostasis.

4 F’s: feeding, fighting, fleeing, fornicating

Question 11

Cerebral Cortex

Answer 11

structurally symmetrical but not functionally symmetrical; LEFT hemisphere controls RIGHT side and vice versa.
*4 lobes (FPOT)

Question 12

Frontal Lobe

Answer 12

executive functions (decisions, goals, etc.)

• Broca’s Area
• Motor Cortex

Question 13

Parietal Lobe

Answer 13

somatosensory cortex; processes skin senses

Question 14

Occipital Lobe

Answer 14

visual cortex

Question 15

Temporal Lobe

Answer 15

auditory cortex

* Wernicke’s Area (language)

Question 16

Association Areas

Answer 16

perception, personality

Question 17

Corpus Callosum

Answer 17

connects 2 hemispheres of the cortex

Question 18

fMRI

Answer 18

hemotopic response (measures changing oxygen levels in brain)

Question 19

PET Scan

Answer 19

sensitive to glucose; drink low-level radioactive substance

Question 20

CAT Scan

Answer 20

good for brain structural; makes 3D brain images

Question 21

EEG

Answer 21

measures electricity in brain (*sleep studies)

Question 22

Right Hemisphere

Answer 22

processes holistically; no language (split brain patients can draw it out but can’t communicate)

Question 23

Left Hemisphere

Answer 23

processes sequentially; has language

Question 24

Brain Plasticity

Answer 24

brain can rewire itself; some functions may move to undamaged parts; dendrites can grow around damage
