Magnetoencephalography

Magnetoencephalography (MEG) is a non-invasive imaging technique that measures the tiny magnetic fields produced by electrical activity in the brain. When neurons in the brain communicate, they generate electrical currents that create magnetic signals. MEG detects these signals using highly sensitive sensors called superconducting quantum interference devices (SQUIDs). This allows scientists and doctors to map brain activity with excellent temporal (time-related) and spatial (location) precision, helping in research, diagnosis, and treatment planning for conditions like epilepsy, brain tumors, or neurological disorders. It provides real-time insights into how different parts of the brain work.
