MEG - DEF

measures tiny magnetic fields produced by electrical activity in the brain

MEG - USE

where and when brain activity occurs mainly during sensory processing (megan enga? megam-la irundhu mazha varum —> sick aguvom, nose — sensory processing).

EEG - DEF

records brain’s electrical activity using electrodes placed on the scalp. (Electrical activity of brain)

EEG - USE

brain-wave patterns, mainly during sleep and changes in electrical activity associated with seizures. (eee eppo varum —> night appo. kadal alaigal..)

PET - DEF

a radioactive tracer to measure metabolic activity in the brain (GLUCOSE —- PETROL)

PET - USE

which brain regions are highly active and how brain uses substances like glucose. — shows glucose use and and metabolic activity in the brain (petrol enga for brain?)

MRI - DEF

uses magnetic fields and radio waves to create detailed images of the brain. (Moolayai padam pidi..)

MRI - USE

used to look at brain’s anatomy, it’s size, shape, structural abnormalities (Moolaiku Oru Padam)

fMRI - DEF

measures changes in blood oxygenation to indirectly identify brain activity. (moolai-oda function enna?)

fMRI - USE

which brain regions become active during tasks like speaking, remembering, and seeing (moolai oda function enna??)

Lesioning - DEF

studies the effect of damage to a specific brain area to understand its role. (oru paguthi seththu pogidichina?)

Lesioning - USE

how damages to a brain region affects abilities (onnu paththi lesson paddikaruthu.. specific onnu paththi.. oru specific area damage agiduchu-na enna aagum).
