Microelectrode Recording and Stimulation

Micro2 and Micro2+stim

Built for microelectrodes, such as high-density intracortical arrays (e.g. Utah arrays), micro-macro sEEG leads (e.g. Behnke-Fried electrodes) and other high-impedance electrodes, the Micro2 front end records small input signals and the Micro2+stim delivers low-output stimulation.

The Micro2 Front End is capable of recording single-units at a sampling rate of 30kHz. Stimulate and record on all 32 channels simultaneously with the Micro2+stim for unparalleled flexibility and control in applications such as closed-loop stimulation and DBS.

Features

  • Designed for high-impedance microelectrodes
  • Integrated filtering, amplification, and 16-bit digitization for high-fidelity signal acquisition
  • Simultaneous recording and stimulation on all channels
  • Programmatic control of waveforms and train parameters
  • Fast-settle circuitry for artifact rejection and rapid recording recovery following stimulation
