TERM 1
Single-cell
recording
DEFINITION 1
Single-Cell Recording is a technique used in research to
observe changes in voltage or current in a neuron. very thin
electrode is inserted into a single neuron. changes in
electrical activity occurring in the cell are then recorded. Not
suited for humans. precise recording of electrical activity.
TERM 2
EEG
DEFINITION 2
Electroencephalography (EEG) is the recording of changes in
electrical activity along the scalp produced by the firing of
neurons within the brain. Suited for humans. relatively
noninvasive but quite imprecise.
TERM 3
ERP
DEFINITION 3
changes in electrical potentials are recorded via electrodes
attached to the scalp. suited for humans. relatively
noninvasive but it does not show actual brain images.
TERM 4
PET
DEFINITION 4
Participants ingest a mildly radioactive form of oxygen that
emits positrons as it is metabolized. changes in
concentration of positions of positrons in target area of the
brain are then measured. suited for humans and it shows
images of the brain.
TERM 5
fMRI
DEFINITION 5
Functional MRI or functional Magnetic Resonance Imaging (FMRI) is
a type of specialized MRI scan. crea tes magnetic fields that that
induces changes in particles of oxyge n atoms. more active areas
draw more oxygenated blood than le ss active areas in the brain.
the difference in the amount of oxyg en consumed, form the basis
of fMRI measurements. suited for hu mans and shows images of
the brain in action, more precise tha n PET.
