Flashcards in Module 6: Tools of Discovery and Older Brain Structures Deck (22):
1

lesion

killing brain cells to see what they control

2

electroencephalogram (EEG)

records electrical activity of the brain, shows function

3

positron emission tomography (PET) scan

detects radioactive glucose to find active areas of brain, shows function

4

magnetic resonance imaging (MRI)

uses magnetic fields and radio waves to produce 3D image of soft tissue, shows structure

5

functional MRI (fMRI)

follows blood flow and tracks oxygen to revel brain activity, shows function

6

computerized axial tomography (CAT) scan

uses x-ray scans to produce cross-sectional images, shows structure

7

diffusion spectrum imaging machine

can map long-distance brain connections

8

hindbrain

medulla, pons, cerebellum, reticular formation, brainstem

9

midbrain

controls sensory processes

10

forebrain

cerebrum, limbic system, thalamus

11

brainstem

primitive structure that controls basic biological functions (heartbeat, breathing)

12

medulla

controls blood pressure, heart rate, breathing

13

pons

transmits info between spinal cord and brain
controls movement and sleep

14

cerebellum

controls balance and motor coordination, nonverbal learning, emotional control

15

cerebellum and pons together control

voluntary movement

16

cerebellum and basal ganglia together control

skill memory

17

reticular formation

network of nerves that receives info from thalamus and sends it to other brain areas
controls arousal

18

thalamus

relays sensory info to appropriate areas

19

limbic system

amygdala, hypothalamus, hippocampus

20

amygdala

aggression and fear; emotions

21

hypothalamus

bodily maintenance (hunger, thirst, temperature)
reward center

22

hippocampus

stores explicit memories
