EEG Scan

EG measures electrical activity in the brain using electrodes placed on the scalp.

Track rapid changes in the brain

Studies using EEG have shown that placebo treatments can alter brain wave patterns, particularly in regions associated with pain and emotional processing

PET scan

utilizes a radioactive tracer to visualize and measure the metabolic activity of cells.

MEG Scan

MEG measures the magnetic fields produced by neural activity.

pinpoint the exact locations of brain activity.

MEG has been used to study how placebo treatments affect brain regions involved in pain perception and cognitive functions.

fmri

measures brain activity by detecting changes in blood flow.

When brain cells are active, they use more oxygen, causing increased blood flow to those areas.
