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

31

Retrograde amnesia

Kind of memory loss

Can't remember events that happened before brain injury

32

Gyri and Sulci

Bumps found on the cortex

33

The cerebral cortex provides _________ to the brain

Increased surface area

34

Visual system DOMINANT hemisphere :

Letters and words

35

Visual system NONDOMINANT hemisphere :

Faces

36

Auditory system DOMINANT hemisphere :

Language - related sounds

37

Auditory system NONDOMINANT hemisphere :

Music

38

Language DOMINANT hemisphere :

Speech, reading, writing, arithmetic

39

Language NONDOMINANT hemisphere :

Emotions

40

Movement DOMINANT hemisphere :

Complex voluntary movement

41

Spatial processes NONDOMINANT hemisphere :

Geometry, sense of direction

42

Prefrontal cortex

Reminds the individual that he or she has something to remember (but does not store an memory traces)

43

Prefrontal cortex communicates with

The reticular formation in the brain stem, telling an individual to wake up or to relax

44

Prefrontal lesions

A person is more impulsive and in less control of his or her behavior or is depressed

Can make vulgar and inappropriate sexual remarks

45

Frontal lobe contains

Association area
Brocas area
Projection area

46

Broca's area

Important for speech production

Usually found in the "dominant" hemisphere - left hemisphere

47

Frontal lobe function

Controls executive function, impulse control, long - term planning, motor function and speech production

48

Parental lobe contains

The somatosensory cortex

49

Parental lobe function

Controls sensations of touch, pressure, temperature and pain; spatial processing; orientation; and manipulation

50

Occipital lobe contains

Visual cortex (aka striate cortex)

51

Occipital lobe function

Controls visual processing

52

Temporal lobe contains

Auditory cortex
Wernicke's area

53

Temporal lobe function

Controls sound processing, speech perception, memory and emotion

54

Cerebral hemispheres

2 : left and right

For most people, left hemisphere is the most dominant one

55

Dominant hemisphere

Usually the left one

Language
Logic
Math skills

Broca's area
Wernicke's area

56

Nondominant hemisphere

Usually the right
