Electrochemical processes constitute the basis of neural activity. They result in brain waves, recordable by means of electrodes placed on the surface of the skull. The advantage of this measurement technique called electroencephalography (EEG) lies in its high temporal resolution allowing for analysis of signals in millisecond-range. Additional to state-dependent activity in different cortical areas, the EEG can also detect differences in reaction to stimuli.
Our laboratory in NB2/59 comprises 256-channel EEG available as well as a Neurofeedback system enabling test persons to train the control of their brain waves.
