different ways of studying the brain
fMRI
functional magnetic resonance imaging, works by detecting changes in the oxygenated blood in the brain from the activity in the specific parts in the brain, increased oxygenated blood flow in certain parts of the brain means more activity
advantages
does not relay on radiation, meaning that there is no damage done to the participants
produces images at very high resolution
limitation
very expensive, there is a time of lag, meaning that the time may not be very accurate
EEG
this is using electrodes planting in the brain which scan the brain for electrical activity, brainwave patterns that are generated from the action of 1000s neurons
advantages
can be used to diagnose epilepsy patients, as they can identify where the electrical activity is coming from,
shows real time where the brain activity
disadvantage
cannot show the exact precise location of the brain activity
ERP
this is EEG when the person reacts to a stimulus, this is to see how the brain reacts to the issue where , ioslates all other actions and looks at this particalur one
advantages
shows more spefic areas of measurement of neural processes than could ever be achieved using raw EEG data
disadvantages
lack of ERP standardisation methodology, between different research studies which makes it difficult to confirm findings
Post- mortom
this is using a dead persons brain to look at, this is usually done onto people who have rare conditions
advantages
can look at a persons brain more in-depth without the worry of hurting the person, as they are dead, can identify key parts of the brain
disadvantage
there is no level of consent, this does not helot the person that they are operating on, additionally they cannot see the brain activity
