Description
Electroencephalography (EEG) is a non-invasive method for recording electrical currents on the surface of the head, which are generated by potential differences in the extracellular space. The electroencephalogram (also abbreviated to EEG) is the graphical representation of this electrical activity. The measurement is risk-free and painless.
Two BrainAmp biosignal amplifiers(Brain Products GmbH) with a total of 64 channels are available in the laboratory for recording electrophysiological signals such as EEG, EMG, EOG and evoked potentials. With the BrainAmp ExG expansion box, the BrainAmp amplifiers can be expanded by a further 16 bipolar channels. AG/AGCL sintered electrodes are used for the measurement, which are mounted on an EASYCAP electrode cap. In addition, 64 active electrodes (actiCAP slim) are available. The impedances are measured automatically with the BrainVision recording software.
Further equipment
Localization system
- Localite TMS Navigator: The Localite TMS Navigator is a navigation system for transcranial magnetic stimulation (TMS). It can be used to plan stimulation sites and to monitor and record the correct patient and coil position.
- Localite EEG PinPoint: The Localite EEG PinPoint is an optical tracking based system for easy and accurate recording of EEG or NIRS positions on the head.
