LOCATION n FUNCTION of BROCA'S AREA

LOC: LEFT part of PREFONTAL CORTEX
FCT: SPEECH (if damaged, individual can't speak correctly)

1

EEG (2)

- electroencephalograph
- device that monitors the ELECTRICAL ACTIVITY of the brain over time by means of recording ELECTRODES attached to the surface of the SCALP
- different brain WAVE patterns are associated w. dif states of MENTAL ACTIVITY
- diagnosis of brain damage n epilepsy

2

TMS (4)

- new technique that permits scientists to temporarily ENHANCE or DEPRESS activity in a specific area of the brain
- "VIRTUAL LESIONS"
- penetrates 2 CM
- delivered from MAGNET mounted on a small PADDLE

3

lesioning (2)

- involves DESTROYING a piece of BRAIN
- typ. done by inserting an ELECTRODE into a brain structure n passing a high frequency ELECTRIC CURRENT thru it to BURN the tissue n disable the structure
- hunger regulation

4

ESB (3)

- electrical stimulation of the brain
- involves sending a weak ELECTRIC CURRENT into the brain structure to stimulate (ACTIVATE) it.
- mostly conducted on ANIMALS but humans play a role to in the context of BRAIN SURGERY

5

MRI (3)

- magnetic resonance imaging
- uses MAGNETIC fields, radio WAVES, and computer enhancement to map out brain structure
- 3DIMENSIONlAL, hi resolution

6

CT scan (2)

- computerized tomography scan
- computer enhanced XRAY of brain structure
MULTIPLE x rays are shot from many ANGLES, n the computer combines the readings to create image from HORIZONTAL slice of brain

7

LOCATION + FUNCTION of PITUITARY (6)

- LOC: BOTTOM of brain
- FCT: "CAPTAIN of the team"
- "DISTRIBUTOR"
- recieves hormones from the HYPOTHALAMUS
- influences METABOLISM
- "sends hormones that activate OTHERS"

8

LOCATION n FUNCTION of HYPOTHALAMUS

LOC: near base of FOREBRAIN
- under THALAMUS
FCT: BASIC biological needs (4Fs: fighting, fleeing, feeding and f***ing)
- LINK b.w brain n ENDOCRINE system
- controls AUTONOMIC NERVOUS SYSTEM

9

fMRI (2)

- functional magnetic resonance imaging
- monitors BLOOD FLOW and OXYGEN CONSUMPTION in brain to identify areas of HI ACTIVITY

10

LOCATION + FUNCTION of RETICULAR FORMATION

LOC: - runs thru HINDBRAIN n MIDBRAIN
- located at CENTRAL core of BRAINSTEM
FCT: contributes to regulation of MUSCLE reflexes, BREATHING, PAIN perception, SLEEP/AROUSAL

11

LOCATION n FUNCTION of HIPPOCAMPUS?

LOC: LIMBIC system
FCT: role in memory processes
Neurogenesis, conversion of memory to long term

12

LOCATION n FUNCTION of THALAMUS

LOC: strucure in the FOREBRAIN
FCT: relays all SENSORY info (except smell) to dif parts of the CEREBRAL CORTEX
- takes ACTIVE role in integrating information

13

PET scan (3)

- positron emission tomography
- examines BRAIN FUNCTION, mapping brain activity
- RADIOACTIVELY TAGGED chemicals introduced into the brain and serve as MARKERS of blood flow or METABOLIC ACTIVITY

14

LOCATION n FUNCTION of TEMPORAL LOBES

LOC: located near the TEMPLES n beneath the PARIETAL lobe
FCT: contains an area devoted to AUDITORY processing, called the PRIMARY AUDITORY CORTEX

15

LOCATION n FUNCTION of AMYGDALA

LOC: LIMBIC system
FCT: role in learning of FEAR responses n processing of other basic RESPONSES

16

LOCATION n FUNCTION of CEREBELLUM

LOC: relatively LARGE and deeply FOLDED structure located next to the BACK surface of the BRAINSTEM
FCT: COORDINATION(writing, typing, playing an instrument) n BALANCE
(Alchohol tests)

17

20

LOCATION n FUNCTION of OCCIPITAL LOBE

LOC: back of the head
FCT: includes cortical area where most VISUAL SIGNALS are sent n visual processing begins
-->PRIMARY VISUAL CORTEX

21

LOCATION n FUNCTION of PARIETAL LOBE

LOC: FORWARD of the occipital lobe
FCT: includes area that registers the sense of TOUCH, called the PRIMARY SOMATOSENSORY CORTEX
