BrainAmp DC
Overview
BrainAmp DC: The most complete solution for neurophysiology recordings
DC recordings have always been very popular in neurophysiological research and in the clinical world as they allow the investigation of cognitive functions as well as many pathologies of the brain. MES, the company that inspired the founding of Brain Products, designed its first DC amplifier for neurophysiology research (DC-MES) back in the 1985 and according to the customers who bought it, it is still working well.
Having contributed to this small part of “history” and as well as relying on its extensive experience in this field, Brain Products pressed forward with the design of the BrainAmp DC. The BrainAmp DC can be used for a variety of applications, ranging from standard EEG/ERP recordings to simultaneous EEG/TMS and EEG/MEG acquisitions, Brain Computer Interface and Neurofeedback.
The BrainAmp DC includes all the outstanding features of the BrainAmp amplifier with the addition of the DC recording mode as well as with multiple hardware filtering options. The setup of the amplifier is fully controllable via the recording software. It is also possible to switch from DC to AC recording mode as well as to select different hardware bandwidths with just one “click” in the software. The BrainAmp DC is a fully portable amplifier which connects to any laptop and can be powered with batteries. Expandable up to 256 channels, it can be paired with all other members of the BrainAmp product family to simultaneously acquire numerous types of neurophysiological data such as ECG, EMG, EOG, GSR (Galvanic Skin Response), acceleration, blood flow, etc.
