Brain Regions And Strucutres

Question 1

Brainstem

Answer 1

The oldest part of the brain and the central brain core, a crossover point

Question 2

Thalamus

Answer 2

• located in middle of brain or top of brainstem
• directs messages to the cortex sensory areas and transmits replies to the cerebellum
• pushes information to different parts of the brain
• Ex. Airport analogy

Question 3

What is the only sense not processed by the thalamus?

Answer 3

Smell

Question 4

Reticular formation

Answer 4

A nerve network that travels through the brainstem into the thalamus
- involved in non verbal learning and memory
- controls arousal

Question 5

Cerebellum!

Answer 5

Involved in movement and non verbal memory

Question 6

Amygdala

Answer 6

-2 bean sized neural clusters
- takes in events and assigns a emotion to them, both positives and negatives

Question 7

Hypothalamus

Answer 7

-neural system below the thalamus
- directs maintenance activities such as hunger, thirst, sexual arousal and fear
- does unconsciously

Question 8

Prader Willli Syndrome

Answer 8

A case in which a part of the hypothalamus is not working and so you are constantly hungry as a result

Question 9

Hippocampus!

Answer 9

• neighbors with the amygdala, it stores the important events/emotions
• long term memory store center
• shape of a seahorse

Question 10

Cerebral cortex

Answer 10

-everything on the outside layer
- 20 billion brain nerve cells
- 300 trillion synaptic connections
- ultimate control and information processing center of the body

Question 11

Cerebral hemisphere

Answer 11

-generally symmetrical
- paired and covered with a intricate fabric of interconnected neural cells

Question 12

Frontal lobe

Answer 12

• at the forehead
• takes up about 30-40% of lobe space

Question 13

Motor cortex

Answer 13

• at the rear of the frontal
• controls voluntary movements

Question 14

Parietal

Answer 14

• at back top of brain
• heavily involved in sensory processing

Question 15

Somatosensory cortex

Answer 15

• involved with parietal
• in between parietal and frontal
• touch and spatial information
• receives incoming messages from skin senses and the movements of body parts

Question 16

Occipital

Answer 16

• has a primary role of vision

Question 17

Visual cortex

Answer 17

• associated with occipital
• located at back of brain
• sends information to other task specialized areas

Question 18

Temporal

Answer 18

• by the ear
• involved in some sensory processing

Question 19

Auditory cortex

Answer 19

• associated with temporal
• receives information from the ears
• circuitous route from one ear to the auditory cortex

Question 20

FPOT

Answer 20

Frontal, parietal, occipital and temporal

Question 21

Prefrontal cortex!

Answer 21

• at the tip of the frontal
• enables social interactions and personality
• if this was damaged, you wouldn’t be you
• the human being powerhouse

Question 22

Neural plasticity and reorganization

Answer 22

• may occur after serious damage especially in young children because the brain is still developing
• at about age 25 the brain ceases to develop
• makes unused brain areas available for use

Question 23

Corpus callosum

Answer 23

Connects two halves and lets information pass back and forth, can be severed in very severe cases such as epilepsy when medications don’t work except it will stop info from being passed

Question 24

Split Brain

Answer 24

When the two hemispheres work indpendently
