Flashcards in STUDYING COGNITIVE Deck (33):
1

density of brain structures determined with x rays

cat

2

anyone can get this test

cat

3

lifetime number should be limited

cat

4

studies brain anatomy

MRI

5

uses really strong magnetic fields but is safe

MRI

6

safer than CT scan

MRI

7

not all individuals can receive this test

MRI

8

aligns all of their protons

MRI

9

studies brain functioning

fMRI

10

detects changes in the blood flow to particular areas of the brain

fMRI

11

increased brain activity should be related to increased blood flow that should be related to increased signals

fMRI

12

using blood flow as a read out, assuming it is an accurate reading of what the brain is doing

fMRI

13

good spatial resolution

fMRI

14

non invasive

fMRI

15

poor temporal resolution

fMRI

16

radioactive substances are injected into the individuals brain, as it becomes stable, light is produced and measured

PET

17

measures light emission

PET

18

detects amount that a substance is being used by different brain regions

PET

19

use it when we want to know about a particular neurotransmitter

PET

20

recording the activity from a single cell

single cell recording

21

looking at electrical activity within the brain

single cell recording

22

an electrode is placed on/in the cell that you're interested in, and its electrical activity will be recorded

single cell recording

23

usually done in animals, or pre surgery

single cell recording

24

directly measuring activity by directly collecting information about electrical information in the brain from thousands of neurons at the time

EEG

25

electrodes are placed on scalp and record brain activity

EEG

26

recordings represent activity of many neurons

EEG

27

useful for overall states of activity: sleep patterns, excess activity

EEG

28

looking at electrical activity from outside of the head

ERP

29

looking at the read outs just after a particular event has occurred

ERP

30

recording magnetic potentials

MEG

31

activity within the brain creates magnetic potentials that can be recorded

MEG

32

localizing source of epileptic activity

MEG

33

locating areas to avoid during surgery

MEG
