Flashcards in Brain Deck (11):
1

Cerebullum

Co-ordinating movement and balance
Checks whether the motor programme being used is correct

2

Temporal lobe

Processing auditory info ie hearing, speech, sound recognition
Memory

3

Parietal lobe

Orientation, movement, sensation, calculation, recognition

4

Occipital lobe

Processing info from eyes ie vision, colour, shape recognition and perspective

5

Frontal lobe

Planning, reasoning, decision making
Forming association and ideas

6

Hypothalamus

beneath the middle part of the brain, maintains the body temp

7

Medulla oblongata

Controls breathing and heart rate

8

MRI

Investigation: Higher quality for soft tissue, difference between abnormal and normal, function only worked out by looking at damaged areas
Medical: Damaged or diseased areas of brain - Tumour cells respond differently in magnetic field, show up lighter, exact size of tumour and its location
3D

9

CT

Investigation - Major structures not functions
Medical - Blood has different densitry (lighter), extent and location of bleeding, work out blood vessels damaged
Radiation and x-rays
2D - brain disease - monitor over illness

10

fMRI

Investigation: detailed and high resolution picture of structure and function
Medical: Study conditions caused by abnormal activity in the brain ie scan before and during seizure find cause
Human acitivites 3D
More oxygenated blood flows to active areas - respond differently

11

PET

Investigating: very detailed and for both
Medical: show if areas are inactive or not
Radioactive tracer into tissues and scanner detects the radioactivity of the tracer
3D - cancers
