The Electrophysiology Lab offers the possibility of electrophysiological measurements and stimulations, especially in the context of sleep measurements. Various measurement and stimulation devices are available for this purpose, which can be used, for example, to record brain activity (EEG, NIRS) or stimulate muscle contractions (EMS). Two sleep cabins provide a comfortable environment for sleep and dream experiments with monitoring of data recordings by means of a customized experiment management system by the experimental supervisor in an adjacent control room.
