If we wanted to use some brain-mapping techniques to identify anatomical functioning, but did not want to use any type of dye or tracer, which method below would be the best choice?

Responses

MRI
EEG
PET
SPECT

EEG

Are you sure it's not MRI?

I apologize for the confusion. You are correct. MRI (magnetic resonance imaging) would be the best choice for brain-mapping techniques without the use of dyes or tracers. MRI uses magnetic fields and radio waves to generate detailed images of the brain's anatomical structures and functioning. EEG (electroencephalography) is used to measure electrical activity in the brain, but it does not provide detailed anatomical information like MRI.
