1

What is the reticular formation associated with?

Consciousness, arousal, attention, movement, and pain

2

Controls speed, intensity, coordination, direction of complex voluntary movements, speech, gives us smoothness and gracefulness to our movements, and balance

Cerebellum

3

Problems with this area result in too little movement or too much movement like in Parkinson's

Basal ganglia

4

Having blindsight when this area is damaged

Occipital lobe

5

Postcentral gyrus. Part of parietal lobe responsible for touch sensory input

Primary somatosensory cortex

6

What do homunculus' represent?

Different parts of the body have different amounts of brain space for sensory and motor

7

Primary visual cortex

Occipital lobe

8

What does the reticular formation do?

Stimulates forebrain

9

This area is the origin of photosensitive epilepsy

Occipital lobe

10

Separates the precentral and post central gyri

Central sulcus

11

Why is the brain wrinkly?

Increase surface area

12

Associated with motor control and reward

Basal ganglia

13

Lowered areas of the brain

Sulci

14

Receives sensory info and regulatory info

Thalamus

15

What does the medulla do?

Vital processes necessary for life including breathing, HR and BP

16

Visual gaze of auditory stimuli. Midbrain

Superior colliculus

17

Plays a role in different stages of sleep and decides if we should wake up or not

Thalamus

18

Part of the hypothalamus, memory. Limbic

Mammillary bodies

19

Primary auditory cortex

Temporal lobe

20

What path does smell take that is different than other senses

It goes to the cortex then the thalamus

21

Impulse control and delayed gratification (waiting for a reward)

Orbitofrontal cortex

22

Where is the periaqueductal gray

Near the area where the CSF would flow through

23

Executive functions like attention, working memory, and goal directed behavior

Dorsolateral PFC

24

What is cerebellar agenesis?

Never growing a cerebellum. The gap is filled with CSF

25

Spatial info processing and stress feedback

Hippocampus

26

Plays key roles in threat detection, fear, excitement, and arousal by sending messages to other areas

Amygdala

27

Gateway to the cortex or sensory switchboard

Thalamus

28

This area is juxtaposed to the somatosensory cortex

Motor cortex

29

Declarative memory formation and stress. Limbic

Hippocampus

30

What makes up the myelencephalon?

Medulla
