Ways Of Studying The Brain Flashcards
Post mortem
Examination of a brain once the person is dead
Post mortem strength
Provides a foundation for studying the brain
Post mortem limitation
Ethical issues of consent
Event related potentials (ERP)
Electro physical response to a specific sensory, cognitive or motor event
ERPs strength
More accurate than EEG
ERP limitation
Extraneous variables need to be eliminated such as background noise
Electroencephalogram (EEG)
Tiny electrical impulses fixed onto a skull cap
EEG strength
Useful in studying stages of sleep and diagnosis of epilepsy
EEG strength
Useful studying stages of sleep and the diagnosis of epilepsy
EEG limitation
EEG signal not useful for pinpointing exact source of activity
Functional magnetic resonance imaging (fMRI)
Detects radio waves, enables researchers to detect which areas are high in oxygen (active)
fMRI strength
Risk free, non invasive
fMRI limitation
It is very expensive
