The human brain emits light (ultraweak photon emissions or UPEs) that reflects changes in cognitive state, suggesting a new dimension of biophysical signaling. These UPEs, generated by radiative decay of excited molecules, correlate with metabolic states and respond dynamically to tasks and stimulation. The study indicates potential for developing a 'photoencephalography' technique to readout functional brain states.
