A visual display of brain activity that detects where a radioactive form of glucose goes well the brain performs a given task

Answer 3

PET scan

Question 4

It’s technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue

Answer 4

MRI

Question 5

A technique for revealing blood flow and therefore brain activity by comparing successive MRI scans

Answer 5

Question 9

The brain sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and Medulla

Answer 9

Thalamus

Question 10

Answer 10

Cerebellum

Question 11

Question 17

Portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position

Answer 17

Parietal lobe’s

Question 18

Portion of the cerebral cortex lying at the back of the head; includes areas that receive information from the visual fields

Answer 18

Occipital lobes

Question 19

Portion of the cerebral cortex lying roughly above the ears; includes the auditory areas, each receiving information primarily from the opposite ear

Answer 19

Temporal lobe’s

Question 20

An area at the rear of the frontal lobe’s that controls voluntary movements

Answer 20

Motor cortex

Question 21

Area at the front of the parietal lobe’s that registers and processes body touch and movement sensations

Answer 21

Sensory cortex

Question 22

Areas of the cerebral cortex that are not involved in the primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking

Answer 22

Association areas

Answer 23

Aphasia

Question 24

Controls language expression-an area, usually in the left frontal lobe, that directs the muscle movements involved in speech

Answer 24

Broca’s area

Question 25

Controls language reception-A brain area involved in language comprehension and expression; usually in the left temporal lobe

Answer 25

Wernicke’s area
