Cerebus

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
