Answer 2

Electroencephalogram

Question 3

Answer 3

PET (positron emission tomography)

Question 4

A series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body

Answer 4

CT (computed tomography)

Question 5

A technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue . MRI scans show brain anatomy

Answer 5

MRI (magnetic resonance imaging

Question 6

A technique for revealing bloodflow and therefore brain activity by comparing successive MRI scans. F MRI scans show brain function

Answer 6

F MRI (functional MRI

Question 7

The oldest part and central core of the brain, beginning where the spinal cord swells as it enters the school; the brainstem is responsible for automatic survival functions

Answer 7

Brainstem

Question 8

The base of the brainstem; controls heartbeat and breathing

Answer 8

Medulla

Question 9

A nerve network in the brainstem that plays an important role in controlling arousal

Answer 9

Reticular formation

Question 10

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 10

Thalamus

Question 11

The little brain at the rear of the brainstem; functions include processing sensory input in coordinating movement output and balance

Answer 11

Cerebellum

Question 12

Donut shaped neural system located below the cerebral hemispheres; associated with emotions and drives

Answer 12

Limbic system

Question 13

To lima beans sized neural clusters in the limbic system; link to emotion

Answer 13

Amygdala

Question 14

A neural structure lying below the thalamus; it directs several maintenance activities, helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward

Answer 14

Hypothalamus

Question 15

The intricate fabric of interconnected neural cells covering the cerebral hemispheres; The bodies ultimate control and information processing center

Answer 15

Cerebral cortex

Question 16

Cells in the nervous system that support, nourish, and protect neurons

Answer 16

Glial cells

Question 17

Portion of the cerebral cortex lying just behind the forehead, involved in speaking and muscle movements and in making plans and judgments

Answer 17

Frontal lobe

Question 18

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 18

Parietal lobe

Question 19

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

Answer 19

Occipital lobe’s

Question 20

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

Answer 20

Temporal lobe

Question 21

In area at the rear of the frontal lobe that controls voluntary movement’s

Answer 21

Motor cortex

Question 22

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

Answer 22

Sensory cortex

Question 23

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

Answer 23

Association areas
