Answer 5

on same side of midline

Question 6

homotopic

Answer 6

connects complementary region of other hemisphere

Question 7

heterotopic

Answer 7

communicates to different brain region

Question 8

forebrain

Answer 8

telencephalon and diencephalon

Question 9

telencephalon

Answer 9

cerebral cortex, basal ganglia and limbic system

Question 10

basal ganglia

Answer 10

controlling involuntary movements

Question 11

diencephalon

Answer 11

thalamus, hypothalamus

Question 12

thalamus

Answer 12

relay station

Question 13

hypothalamus

Answer 13

controls autonomic nervous system and endocrine system

Question 14

midbrain

Answer 14

mesencephalon

Question 15

mesencephalon

Answer 15

motor movement of the eye
auditory and visual processing

Question 16

hindbrain

Answer 16

metencephalon
myelencephalon

Question 17

metencephalon

Answer 17

cerebellum, pons

Question 18

myelencephalon

Answer 18

medulla oblongata

Question 19

resting membrane potential

Answer 19

K+ channels close and Na+ channels reset

Question 20

Depolarisation

Answer 20

Na+ channels open so Na+ flows in

Question 21

Repolarisation

Answer 21

K+ channels open and K+ leaves the cell

Question 22

EEGs

Answer 22

measures scalp activity, electrical activity of the brain

Question 23

EEG strengths

Answer 23

relatively cheap, portable, good temporal resolution

Question 24

EEG limitations

Answer 24

poor spatial resolution
only detects activity on surface of cortex

Question 25

Electrophysiology

Answer 25

recording of action potentials in giant axon

Question 26

Electrophysiology strengths

Answer 26

records directly from individual neurons

Question 27

Electrophysiology limitations

Answer 27

invasive and penetrates brain can't investigate network of multiple neurons

Question 28

MRI

Answer 28

magnetic field passes through persons head causing hydrogen atoms to align

Question 29

fMRI

Answer 29

as brain region uses energy this causes increased blood flow/ blood vessels more visible

Question 30

MRI strengths

Answer 30

high spatial resolution

Question 31

MRI limitations

Answer 31

very expensive, requires large specialist facility

Question 32

PET

Answer 32

uses radioactive substances to visualize glucose metabolism or receptor function

Question 33

PET strengths

Answer 33

can detect different chemicals in the brain

Question 34

PET limitations

Answer 34

expensive and requires specialist facilities and staff low spatial resolution
