The Cerebus system is a highly-configurable, easy-to-use multichannel data acquisition system for animal neurophysiology experiments. The Cerebus Front-End Amplifier and Neural Signal Processor captures, processes, and analyzes action potentials (spikes), field potentials, and other physiological signals in relation to experiment state events – in real time.

Neural Signal Processor – Real time processing for up to 128 electrodes, 16 auxiliary analog channels, and individual TTL or strobed word experiment events (multiple systems can be synchronized for higher channel counts)

128-Channel Front-End Amplifier – Amplifies, filters, digitizes neural signals before converting to a single, multiplexed optical output.

The Cerebus system is configurable for in vivo (bird, rodent, feline, monkey) and in vitro (cell culture, brain slice) preparations to assist in the study of:

  • Sensory perception
  • Motor control
  • Attention, cognition, and decision making
  • Learning and memory
  • Drug and toxin effects
  • Epilepsy
  • Parkinson’s
  • Neuroprosthetics
  • Brain-machine interfaces
  • Neurostimulation therapies
  • Ultra-compact design
  • Fiber-optic link for reduced system noise
  • 8-, 16-, 32-, 64-, 96-, 128- and 256-channel recording (16 bit)
  • Continuous recording of spikes and field potentials (30 kHz)
  • Compatible with low and high-impedance electrodes (individual metal microelectrodes, microelectrode and microwire arrays, planar silicon probe, ECoG grids, and surface EEG/EMG/EKG electrodes)
  • Flexible I/O options for synchronizing with behavior, stimulus, and video systems
  • Per-channel selection of digital filter/sampling rate
  • Adaptive spike detection, 3D spike sorting
  • Electrode impedance/crosstalk measurements
  • Digital noise (line, magnetic) cancellation
  • Interface to NeuroExplorer, Spike2, MATLAB, C/C++, and other 3rd-party software
  • Parallel, multi-PC control and operation
  • Remote control of data acquisition and storage
