Q

hindbrain

A

metencephalon
myelencephalon

17
Q

metencephalon

A

cerebellum, pons

18
Q

myelencephalon

A

medulla oblongata

19
Q

resting membrane potential

A

K+ channels close and Na+ channels reset

20
Q

Depolarisation

A

Na+ channels open so Na+ flows in

21
Q

Repolarisation

A

K+ channels open and K+ leaves the cell

22
Q

EEGs

A

measures scalp activity, electrical activity of the brain

23
Q

EEG strengths

A

relatively cheap, portable, good temporal resolution

24
Q

EEG limitations

A

poor spatial resolution
only detects activity on surface of cortex

25
Q

Electrophysiology

A

recording of action potentials in giant axon

26
Q

Electrophysiology strengths

A

records directly from individual neurons

27
Q

Electrophysiology limitations

A

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

28
Q

MRI

A

magnetic field passes through persons head causing hydrogen atoms to align

29
Q

fMRI

A

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

30
Q

MRI strengths

A

high spatial resolution

31
Q

MRI limitations

A

very expensive, requires large specialist facility

32
Q

PET

A

uses radioactive substances to visualize glucose metabolism or receptor function

33
Q

PET strengths

A

can detect different chemicals in the brain

34
Q

PET limitations

A

expensive and requires specialist facilities and staff
low spatial resolution
