Measuring Brain Activity/ Lesioning

Question 1

Lesioning

Answer 1

Intentionally damage brain of animals

Question 2

Transcranial Magnetic Stimulation (TMS)

Answer 2

electromagnetic pulse delivered to targeted area od brain

Temporarily disrupts brain activity

Question 3

Computerized Tomograph (CT)

Answer 3

X rays sent through braincreates image base on density of tissue

Question 4

Magnetic Resonance Imaging (MRI)

Answer 4

Images of brain created based on how different areas absorb/release energy while in an energy field
More accurate images

Question 5

Diffusion Tensor Imaging

Answer 5

Measures white matter pathways in brain

Question 6

Electroencephalogram (EEG)

Answer 6

Measure patterns of brain activity with use of multiple electrodes attached to scalp

Question 7

Event Related Potentials (ERP)

Answer 7

-Same as EEG but computer records when stimulus was given

Can collect average pattern of data

Question 8

Magnetoencephalography (MEG)

Answer 8

Measures tiny magnetic fields created by electrical activity of nerve cells in brain
Not clear to see where brain activity is occurring

Question 9

PET

Answer 9

radioactive isotope injected into blood, moves to regions of brain during activity

Question 10

White Matter

Answer 10

bundles of connected neurons in cerebral cortex

Question 11

Chronic Traumatic Encephalopathy (CTE)

Answer 11

blow to head causes quick stretching of axons (twist and tear, are damaged)

Neurons die and tau proteins build up

Only diagnosable via autopsy, maybe can use PET scan
