The QuickAmp 136 (left) is a high input-impedance amplifier capable of measuring and recording up to 128 channels of electroencephalographic (EEG) data, as well as eye (EOG), muscle (EMG) and other physiological signals. It is used for Brain-Computer Interface research, in which brain signals are desired with low noise, high temporal resolution and as high spatial resolution as possible, and where EOG and EMG signals are also required for artefact control. The device is USB-2 compatible, allowing for great flexibility of deployment. It was manufactured and supplied by BrainProducts GmbH as part of a complete system including two 128-channel electrode caps. The manufacturer’s recording software also acts as a server, allowing data to be streamed over TCP/IP with very little delay to our own custom-written analysis software, which is integrated with the de facto standard in online biosignal analysis software, the BCI2000. The hardware is CE-certified as safe for use as a medical device and, in combination with a laptop computer, is highly portable, making it possible for with patients and paid subjects alike. As of 2008 we have also laboratory that has been optimized for acquiring noise-free EEG signals, using older 40-channel equipment by Precision Instruments, Inc (right).
