Integrated Wireless Neural Recording and Electrode Positioning System

AbstractIn neurophysiological research, the recording of brain activity in animals is fundamental. Conventional wire-based technologies allow such recordings only in movement-restraint animals. Head-mounted wireless recording technologies allow investigating a broader spectrum of behaviors and have the potential to improve animal welfare and mark an important step towards implantable neuroprosthetic devices. We developed a lightweight, head-mountable neural recording system, which allows bidirectional communication for remote signal acquisition on the one hand and remote pre-amp gain adjustments and microelectrode position adjustments, on the other hand
