Ways to Study the Brain

Question 1

Simulation

Answer 1

• Electric

- Put an electrode in a specific part of the brain, turn on electricity, & will do the specific behavior

Question 2

Accidents

Answer 2

-Phineaus Gage (his personality changed & found out frontal lobe holds personality)

Question 3

Imaging

Answer 3

-MRI, CAT, PET, fMRI, EEG, EKG

Question 4

Lesion

Answer 4

-Intentional removal or destruction of part of the brain

Question 5

MRI

Answer 5

(Magnetic Resonance Imaging)

• Uses strong magnetic field * radio waves to create detailed images of organs & tissues
• Non-invasive

Question 6

fMRI

Answer 6

(Functional Magnetic Resonance Imaging)

• Uses MRI tech. to measure cognitive activity by monitoring blood flow to certain areas of the brain (neutrons active)
• Tests what tissues DO rather than how they look

Question 7

CAT (CT) Scan

Answer 7

(Computerized Axial Tomography)

• Combines data from several x-rays to produce a detailed image of structures inside of the body
• Can potentially cause cancer

Question 8

PET Scan

Answer 8

(Positron Emission Tomography)

• Imaging reveals how your tissues & organs are functioning
• Uses a radioactive drug (tracer) to show activity (can detect disease before it appears)
• Can have false info

Question 9

EEG

Answer 9

(Electroencephalogram)

• Evaluates electrical activity in the brain, tracks & records brain wave patterns
• Small flat metal discs (electrodes) are attached to the scalp w wires & analyze the electrical impulses in brain & send to computer

Question 10

EKG

Answer 10

(Electrocardiogram)

-Records electrical signals from your heart
