Imaging techniques: Methods that allow researchers to visualize and study structures or processes within living organisms, such as MRI or fMRI.
Electroencephalography (EEG): A noninvasive technique that measures electrical activity in the brain using electrodes placed on the scalp.
Transcranial magnetic stimulation (TMS): A noninvasive procedure that uses magnetic fields to stimulate specific regions of the brain and temporarily alter neuronal activity.
