Modules 11 and 12: The Brain

Question 1

EEG

Answer 1

amplified recording of brain waves and electrical activity

Question 2

MEG

Answer 2

measures the brain’s natural electrical activity, maps brain functions as well as epileptic seizures

Question 3

CT

Answer 3

x-ray of the brain, indentifies TBIs

Question 4

PET

Answer 4

tracks where a temporarily radioactive form of glucose goes while the brain performs an activity

Question 5

MRI

Answer 5

map of the brain’s structure

Question 6

fMRI

Answer 6

shows blood flow and brain activity (functional mri)

Question 7

Medulla

Answer 7

Base of the brainstem. controls heartbeat and breathing

Question 8

pons

Answer 8

above the medulla. coordinates movement and sleep

Question 9

thalamus

Answer 9

top of the brain stem. brain’s sensory control center, receives information from all senses except smell and reroutes it to higher brain structures

Question 10

reticular formation

Answer 10

neuron network extending from the spinal cord right up through the thalamus, filters incoming stimuli and controls arousal

Question 11

cerebellum

Answer 11

enables nonverbal learning and skill memory

Question 12

Limbic system

Answer 12

center to controlling emotions and drives, consists of the hypothalamus, the amygdala, and the hippocampus

Question 13

amygdala

Answer 13

emotional and survival responses, “fight or flight”

Question 14

hypothalamus

Answer 14

maintains homeostasis

Question 15

hippocampus

Answer 15

processes conscious, explicit memories

Question 16

cerebral cortex

Answer 16

brain’s main processing center, controls four different lobes

Question 17

frontal lobe

Answer 17

involved in speaking, muslce movements, and in making plans and judgements

Question 18

parietal lobe

Answer 18

top of the head, receives sensory input and body position

Question 19

occipital lobe

Answer 19

involved with seeing, processes visual cues

Question 20

temporal lobe

Answer 20

involved in hearing, processes sounds

Question 21

Motor cortext

Answer 21

involved in “motor” movements

Question 22

somatosensory cortex

Answer 22

area that registers and processes body touch and movement sensations

Question 23

auditory cortex

Answer 23

located just above the temporal lobes, sound is processed fully

Question 24

visual cortex

Answer 24

located in occipital lobes, processes visuals and sends info teh identify what they are

Question 25

association areas

Answer 25

most of the brain's thinking, remembering, and learnign

Broca's Area

Answer 26

expressive language

Question 27

wernickes area

Answer 27

receptive language

Question 28

plasticity

Answer 28

brain's ability to change via reorganizing after damage or building new pathways built on experience

Question 29

neurogenesis

Answer 29

producing new neurons, brain's attempt to self repair by reorganizing existing tissue or mend itself.
