14
Q

prefrontal cortex controls

A

higher cognition. decision making

15
Q

grey matter in human PFC

A

1.2 x higher than chimps

16
Q

neurons percentage

A

50%, signals through electrical & chemical

17
Q

Glia

A

50%,

18
Q

microglia

A

phagocytosis, rubbish clearing

19
Q

astrocytes

A

energy to nervous tissue

20
Q

oligodendrocyte

A

act as axons

21
Q

neural communication

A

receives info. from dendrites+ communicate down axon to synapse

22
Q

grey matter

A

high concentration of neurons

23
Q

white matter

A

long heavily myelinated axons across the brain

24
Q

neuro modulation

A

3rd neuron releasing NT that increase or decrease transmission

25
Q

EEG

A

polarised charge negative-neuron positive-synapse . EEG measures. opposite dipole from dendritic AP

26
Q

event related potential

A

measure of potential related to event

27
Q

positives of EEG

A

shows when neural activity occurs

28
Q

Balconi & Ferrari 2012

A

shown faces negative - high response in posterior low response in Frontal regions opposite for positive

29
Q

magnetic resonance imaging

A

magnet aligns to protons. radio frequency releases proton energy measured by MRI

30
Q

functional MRI

A

neurons need oxygen MRI measures energy from iron protons

31
Q

disadvantages of FMRI

A

cant infer causation due to external factors & don’t know what regions are actually doing

32
Q

Brain lesions

A

Behaviour changes due to lesions
Surgery/ disease

33
Q

Quian 2005

A

neuron in mid temporal gyrus-monkeys only responded to images of Jennifer Aniston

34
Q

Transcranial magnetic stimulation

A

magnetic field generates electric current+ disrupts neurons-turn areas on & off
