Neuroscientific Methods Flashcards
what are two anatomical methods of study?
computer tomography (CT scan) cat scan MRI scan
3 ways of monitoring brain activity?
electroencephalogram (EEG)
Positron emission topography (PET scan)
functional megnetic resonance imaging (fMRI)
what us an EEG?
attatching electrodes to head, ampifying oltage and allowing brain activty to be recorded
what is a PET scan?
looking t blood flow to see patterns of activity across the brain, area where activity is higher = red areas become larger and show which part of brian affected by differnet factors
what is fMRI?
a step further than a PET scan
what is spatio-temporal resolution?
need many mehtods of activity recording due to this, spatio level is down to the neuron, microbe onto the membran eof a cell = very precise process
what are the limits of EEG, fMRI and single recording unit?
poor spatial resolution
medium spatial resolution, low temporal reoslution
high spatial and temporal resolution
what is poor spatial resolution?
misses fine details/ interactions between groups or individual neurons
what is high spatial resolution?
what the rest of the brain is doing
what is high temporal resolution?
can we ‘see’ the relevant signal, can we store enough data?
