How does MEG provide insights into brain function?

Magnetoencephalography (MEG) provides insights into brain function by capturing magnetic fields generated by neural activity. Neurons in the brain produce tiny magnetic fields as they generate electrical impulses during communication. MEG technology uses highly sensitive magnetometers to detect these magnetic fields, allowing researchers and clinicians to map brain activity in real-time with high temporal and spatial resolution.

This capability enables the understanding of brain functions related to specific tasks, cognitive processes, and even the localization of critical areas for functions such as movement or speech before surgical interventions. MEG is distinct in its ability to provide direct measurements of neural activity, making it a valuable tool in both research and clinical settings for elucidating various aspects of brain function and connectivity.
