Simultaneous and continuous recording and processing of different noninvasive neuromonitoring parameters were carried out, including spontaneous and evoked bioelectrical brain activities obtained by new “active electrodes,” transcranial Doppler sonographic measurements using robotic probes, a multiscan principle for three-dimensional transcranial Doppler imaging, and recording of near-infrared spectroscopic data. The recording and processing were carried out over periods of some hours with a new recording technique integrated in a helmet construction.
