Short Description

256-channel ”high-density“ EEG with PhysioBox for external sensors as required for long-term recordings (including sleep). The electrical geodesic hdEEG system allows to simultaneously record from 256 EEG channels as well as external physiological sensors like eye movements, muscle activity or respiratory signals. The device comes with EEG caps which can be applied very quickly (for short-term recording of approx. 1 hour) as well as special “gel-based” EEG nets for long-term recording. The short-term nets are also available in small sizes as required for recordings in babies and toddlers.

Visual and auditory stimulation is realized with additional laptops and appear as ‘triggers’ time-locked to the stimulation in the EEG. Ambulatory (IR-) cameras allow to record videos at the same time as the hdEEG recording.

Research Services

EEG acquisition of projects related to’learning during sleep‘ (i.e., memory consolidation across sleep)
Information processing of auditory stimuli presented during sleep
“Baby EEG” right after birth as well as in toddlers
Recording of long-term polysomnography in patients who had a severe brain injury (VS/UWS and MCS) in to improve diagnostic and potentially also assist prognostic statements

Methods & Expertise for Research Infrastructure

The scientific application covers 3 areas:
(1) Application for long-time recordings in non-communicative (post comatose) patients
(2) Application in newborns for the registration of EEG/ECG/EMG data after acoustic stimulation and
(3) Recording during sleep with healthy individuals
Our methodological expertise is in the field of time-frequency research using the wavelet analyses, phase calculations (PLI, PLV) and classic ERP analyses.
