fMRI

Measures brain activity by detecting changes in blood oxygen levels using a strong magnetic field and radio waves in a large scanner

EEG

Records electrical brain activity with electrodes placed on the scalp, capturing rapid neural signals non-invasively

MEG

Detects magnetic fields produced by neuronal electrical currents using a helmet-like sensor array in a magnetically shielded room

PET

Uses injected radioactive tracers to measure metabolic activity in the brain, providing images of brain function with a specialised scanner

MRI

Creates detailed images of brain anatomy using magnetic fields and radio waves without involving radiation

DTI

An MRI technique that maps white matter pathways by tracking water molecule diffusion in brain tissues
