Methods For Studying Relation Between Psychological And Nervous System Functions

Question 1

Lesion method

Answer 1

Study of the behavioral effects of tissue damage to the nervous system:

Clinical- accidents
Experimental- damage for therapy, research

Question 2

Electrical recording EEG

Answer 2

records fluctuations in electrical activity

People show differing EEG depending on their state

Question 3

Single neuron recording

Answer 3

Records action potentials, “single unit”, can be recorded in the hippocampus

Question 4

Microdialysis

Answer 4

Chemical recording, probes, sampling of cerebrospinal fluid retrieved from the spinal cord

Involve the collection of extra cellular fluids by implanting a porous fiber in the brain, fluid samples can be chemically analyzed for the presence of neurotransmitters, metabolic breakdown products or other substances

Question 5

Drugs

Answer 5

Cause neurochemical changes 
Alter neurotransmitter synthesis
Block storage of transmitter 
Stimulate or reduce release
Stimulate or block receptors 
Block enzymatic breakdown or uptake of transmitter

Question 6

CT or CAT

Computerized tomography

Answer 6

Imaging method which shows the brain structure

Computerized axial tomography type of x ray that allows scientists and clinicians to see bone and brain tissue

Question 7

sMRI

Structural magnetic resonance imaging

Answer 7

Finer than a CT scan scans brain

Question 8

fMRI

Functional magnetic resonance imaging

Answer 8

Imaging method which measures the flow of oxygenated blood, amygdala

Gives the ability to look at the changes in the oxygen in the blood as it flows in and out of certain areas of be brain which are used during certain tasks and events

Question 9

PET

Positron emission tomography

Answer 9

Imaging method related to metabolic activity, glucose

Allows The ability to look at the brain of a living organism that is awake during the process

Question 10

MRI magnetic resonance imaging

Answer 10

More advanced than CAT scan yields better picture of the nervous system, static structure of he brain

Question 11

CBF cerebral blood flow

Answer 11

Are monitors to examine the function of the nervous system is the awake person

Question 12

Antagonists

Answer 12

Block neurotransmitter receptors

Question 13

Agonists

Answer 13

Stimulate receptors

Question 14

Dopamine

Answer 14

Example of a chemical transmitter

Question 15

Haldol

Answer 15

Example of a dopamine receptors blocker which effectively reduces the symptoms of schizophrenia

Question 16

Parkinson’s disease

Answer 16

Motor disease that results in the degeneration of dopamine neurons can be treated with dopamine agonists
