Reticular Formation

Answer 9

A collection of nerve fibers that tunnel through the brainstem that are involved with alertness and arousal.

Homunculus

Answer 20

A visual representation that shows how much brain area is devoted to the sensations of each body part, showing how sensitive to stimuli they are

Question 21

Occipital lobe

Answer 21

One of the four main lobes, contains areas that process visual information

Question 22

Answer 22

The part of the cortex that processes the visual information and sends it to be further processed in other visual areas. (Located in the Occipital lobe)

Question 23

Temporal lobe

Answer 23

One of the four lobes of the brain, primarily processes auditory information, also is important in memory formation

Question 24

Angular Gyrus

Answer 24

An area of the brain involved in reading and writing. (Located at the lower part of the Parietal lobe)

Question 25

Auditory cortex

Answer 25

The part of the cortex that processes auditory information. (Located in the Temporal lobe)

Question 26

Thalamus

Answer 26

A structure on the top of the brain stem serves as are lay station for impulses from the body to areas of the cerebral cortex

Question 27

Limbic System

Answer 27

A group of brain structures that are involved in emotion, learning, memory, and some basic drives

A structure that is involved in the creation of memories and learning. (Located in the temporal lobe, and part of the Limbic system)

Question 29

Amygdala

Answer 29

A structure that is important for emotion, threat/fear perception, and memory. Located in the Temporal lobe and part of the Limbic system)

Question 30

Hypothalamus

Answer 30

A structure that controls the autonomic functions of the body and works with the pituitary gland to control hormones

Question 31

Nucleus Accumbens

Answer 31

A structure that mainly functions in the pleasure/reward circuit and reinforcing behaviors

Question 32

Basal Ganglia

Answer 32

A structure that is involved with voluntary movement

Question 33

What are the three major regions of the brain and their locations?

Answer 33

1) Hindbrain, located at the bottom of the brain 2) Midbrain up from the base of the brain and is surrounded by the forebrain 3) Forebrain is the top of the brain and is what most people visualize about the brain

Question 34

Explain what brain lateralization is

Answer 34

This is the differing functions between the right and left hemispheres of the brain

Question 35

Describe what roles the left and right brain are better at due to hemispheric specialization

Answer 35

An individual is not right or left brained. The left hemisphere is generally better at recognizing words, letters, interpreting language, and the right hemisphere is generally better at spatial concepts, facial recognition, and discerning direction
