Flashcards in 4.25 Cerebrum 2 Deck (19):
1

What does the cerebrum allow us to do?

- perceive
- produce movement
- language
- understand visual cues
- nonverbal communication
- decision making
- remembering

etc etc etc

2

What are the two major components of the cerebrum?

- diencephalon
- cerebral hemispheres

3

What are the parts of the diencephalon?

- thalamus
- hypothalamus
- epithalamus
- subthalamus

4

general function of the thalamus

monitors cortical activity

5

How many groups of thalamic nuclei?

3

6

What are the thalamic nuclei groups separated by?

intramedullary lamina

7

What are the 3 groups of thalamic nuclei?

- anterior
- medial
- lateral

8

thalamic nuclei groups: anterior consists of

association nuclei

9

What are association nuclei?

- reciprocal connections that allow filtering of information
- helps with adjusting emotions, memories, etc

10

thalamic nuclei groups: Which ones are only made up of association nuclei?

anterior
medial

11

thalamic nuclei groups: What does the lateral group consist of?

2 tiers
- ventral: relay nuclei
- dorsal: association nuclei

12

What is the function of the relay nuclei in the ventral lateral thalamic nuclei group?

gets info to cortex

13

What is the hypothalamus important for?

- homeostasis
- reproductive activities and behaviors
- defensive behaviors
- emotional expressions
- circadian rhythms
- endocrine regulation

14

What does the hypothalamus integrate?

- autonomic ⬌ behavior
(i.e. stressed » eating cupcakes)

- coordination of digestive activity with food seeking

15

What is in the epithalamus?

pineal gland

16

function of the pineal gland

produces melatonin

17

function of melatonin

keeps us on a normal diurnal schedule

18

subthalamus aka

STN

19

function of STN

- major player in BG circuits
- facilitates GPi
