Chapter 3: Methods of Cog Neuro

Question 1

Provides focal stimulation of brain noninvasively; directly stimulates neurons

Answer 1

Transcranial magnetic stimulation (TMS)

Question 2

What do CAT, MRI, and DTI all do?

Answer 2

Give information on structure of the brain

Question 3

Inject dye into blood and pass x-rays through the head; allows 3D reconstruction

Answer 3

CAT

Question 4

Maps brain areas in detail using magnetic properties of atoms that make up organic tissue

Answer 4

MRI

Question 5

Neuroimaging that uses an MRI to image all white matter pathways (Myelination)

Answer 5

DTI

Question 6

What do EEG, ECoG, Single-cell recording, and MEG have in common?

Answer 6

They all measure neural activity

Question 7

Used to monitor the activity of individual neurons; measures change in membrane potential

Answer 7

Single-cell recording

Question 8

An array of electrodes is inserted into the brain to help understand the activity of many cells

Answer 8

MultiUnit recording

Question 9

A grid of strip electrodes is inserted in the brain to help understand the activity of many cells

Answer 9

ECoG

Question 10

Are single cell recordings, ECoG, and multiunit recordings invasive or noninvasive

Answer 10

invasive

Question 11

Surface recording made from electrodes placed on scalp; good for temporal resolution

Answer 11

EEG

Question 12

Measures magnetic signals generated by the brain

Answer 12

MEG

Question 13

What is hemodynamic response?

Answer 13

Detect change in blood flow

Question 14

Measure metabolic activity or blood flow changes in the brain by monitoring the distribution of a radioactive tracker

Answer 14

PET

Question 15

Utilizes an MRI to track blood flow changes in the brain that may be correlated with local neural changes

Answer 15

fMRI

Question 16

A change in electrical activity that is time-
locked to specific events such as the presentation of a stimulus or
onset of a response

Answer 16

Event-related potentials-

Question 17

What two imaging techniques exemplify hemodynamic response?

Answer 17

PET and fMRI

Question 18

Experimental design that consist of blocks of multiple
trials of the same type

Answer 18

Block design
