1

Hypothalamus function

Maintains homeostasis and integrates with the endocrine


Hunger and thirst; emotion

Feeding, fighting, flighting , fucking

2

Lymbic system function

Emotion & memory

3

Basal ganglia function

Movement

4

Cerebral cortex function

Complex perceptual, cognitive and behavior processes.

Determining Intelligence
Determining Personality
Motor Function
Planning and Organization
Touch Sensation

5

Inferior and superior colliculi is found in what major division of the brain and what is the function?

In the mid brain

Sensorimotor reflexes

6

Cerebellum function

Helps maintain posture and balance and coordinates body movements

7

Medulla oblongata function

Vital functioning (breathing, digestion)

8

Reticular formation function

Arousal and alertness

9

Hindbrain

Controls balance, motor coordination, breathing, digestion and general arousal processes such as sleeping and waking

10

Hindbrain is also known as

Rhombencephalon

11

Pons

Lies in the medulla and contains sensory and motor pathways between the cortex and medulla

12

Midbrain is also known as

Mesencephalon

13

Midbrain

Deals with involuntary reflex responses triggered by visual and auditory stimuli

14

Forebrain also known as

Prosencephalon

15

Telencephalon forms the:

Cerebral cortex
Basal ganglia
Limbic system

16

Diencephalon forms the

Thalamus
Hypothalamus
Posterior pituitary gland
Pineal gland

17

Thalamus function

Consciousness, sleep and sensory interpretation

18

Electroencephalogram (EEG)

Noninvasive mapping procedure
Electric activity generated by larger groups of neurons
Electrodes on scalp

19

Regional cerebral blood flow (rCBF)

Noninvasive mapping procedure

Detects broad patterns of neural activity based on blood flor to different parts of the brain

Relies on the assumption that when a specific cognitive function activates certain regions of the brain, the blood flow to those regions increase.

20

Lateral hypothalamus

The hunger center


Has special receptors to detect when the body needs more food or fluids

21

Ventromedial hypothalamus (VMH)

The "satiety center"

Provides signals to stop eating

Brain lesions in this area lead to obesity

22

Anterior hypothalamus

Controls sexual behavior

Can also regulate sleep and body temperature

23

Posterior pituitary

Secretes: Antidiuretic hormone (ADH) and oxytocin

24

Pineal Gland

Secretes: melatonin

25

Basal ganglia

Found in the middle of the brain

Coordinates muscle movement

26

Destructions of portions in the basal ganglia lead to :

Parkinson's disease

27

Septal nuclei

Romario pleasure centers in the brain

Mild stimulation leads to intense pleasure

28

Amygdala

Controls fear and aggression

29

Hippocampus

Plays a role in learning and memory

Communicates with parts of the Limbic system through an extension called the fornix

30

Anterograde amnesia

Kind of memory loss

Can't remember long term memories but could remember events that occurred before brain injury
