Man being scanned by a magnetoencephalograph (MEG) scanner whilst responding with a fibre-optic button box under his hand to cues from visual stimulations of, for instance, faces projected onto a screen in front of him. The reactions within his brain are recorded by the scanner, which detects the extremely small magnetic fields generated by different areas of neural activity. The resulting data is used with other neuro-imaging techniques to investigate psychiatric and neurological disorders such as ADHD, epilepsy and age-related memory and cognitive syndromes such as Alzheimer's and dementia. The eye-tracking device in front of the subject gives data on the gaze related to the brain activity and also relays information on any blinking or head movement which may influence the neural currents. Photographed at the Oxford Centre for Human Brain Activity, UK.
