The center is equipped with four EEG systems that are installed in four soundproof chambers. Each chamber is equipped with a BrainAmp DC®amplifier: in addition to the normal features of an AC amplifier, the DC recording mode allows multiple hardware filtering options.
Through the recording software (Brain Recorder®) it is possible to control all the amplifier options, including the switch from DC to AC recording mode as well as to select different filtering bandwidths. The Brain Amp DC® is more stable than older EEG systems in a variety of applications, and it supports simultaneous EEG/TMS and EEG/MEG input to Brain Computer Interface and Neuro feedback.
Two chambers are equipped with a 64-channel system and two chambers with a 32-channel amplifier. The Brain Amp DC® is a portable amplifier which connects to any laptop and can be powered with batteries. Thus,the 32-channel amplifiers can be used for experiments run outside the center (e.g., in schools or hospitals) as well.
Each chamber is also equipped with sets of electrodes that can be arranged on EasyCaps® in whatever pattern is needed for a given experiment. Each cap has 74 equidistant electrode positions(10%-System); several different sizes are available, including one ssuitable for children.
For off-line EEG/ERP analyses, the Vision Analyzer® 2.1 software is available on each computer via a network key.
