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
