UNIT 2

Question 1

Neuropsychologists

Answer 1

those who explore the relationships between brain/nervous systems and behavior.
or- biological psychologists, biopsychologists, behavioral geneticists, physiological psychologists, and behavioral

Question 2

CAT

Answer 2

creates a computerized image using X-rays passed through the brain to show structure and/or the extent of a lesion

Question 3

MRI

Answer 3

creates more detailed computerized images using a magnetic field and pulses of radio waves that cause emission of signals that depend upon the density of tissue.

Question 4

EEG

Answer 4

an amplified tracing of brain activity produced when electrodes positioned over the scalp transmit signals about the brain’s electrical activity (“brain waves”) to an electroencephalograph machine.

Question 5

Evoked potentials

Answer 5

EEGs resulting from a response to a specific stimulus presented to the subject.

Question 6

PET

Answer 6

shows brain activity when radioactively tagged glucose rushes to active neurons and emits positrons.

Question 7

fMRI

Answer 7

shows brain activity at higher resolution than the PET scan when changes in oxygen concentration near active neurons alter magnetic qualities.

Question 8

CNS

Answer 8

brain and spinal cord.

Question 9

PNS

Answer 9

ortion of the nervous system outside the brain and spinal cord; includes all of the sensory and motor neurons, and subdivisions called the autonomic and somatic nervous systems.

Question 10

ANS

Answer 10

subdivision of PNS
motor nerves that involuntary move.
Its sympathetic nervous system prepares the body for “fight or flight”; the parasympathetic nervous system causes bodily changes for maintenance or rest.

Question 11

Sympathetic nervous system

Answer 11

subdivision of PNS and ANS whose stimulation results in responses that help your body deal with stressful events.

Question 12

Parasympathetic nervous system

Answer 12

subdivision of PNS and ANS whose stimulation calms your body following sympathetic stimulation by restoring normal body processes.

Question 13

Somatic nervous system

Answer 13

subdivision of PNS that includes motor nerves that stimulate skeletal (voluntary) muscles.

Question 14

Spinal cord

Answer 14

portion of the central nervous system below the level of the medulla. Brain-portion of the central nervous system above the spinal cord.

Question 15

Convolutions

Answer 15

folding-in and out of the cerebral cortex that increases surface area of
the brain.

Question 16

Contralaterality

Answer 16

control of one side of your body by the other side of your brain.

Question 17

Medulla oblongata

Answer 17

regulates heart rhythm, blood flow, breathing rate, digestion, vomiting.

Question 18

Pons

Answer 18

includes portion of reticular activating system or reticular formation critical for arousal and wakefulness; sends information to and from medulla, cerebellum, and cerebral cortex.
