The CerePlex Exilis is a neural recording platform for freely moving small animal models. It delivers unprecedented quantities of neural data via high-fidelity wireless transmission.
The CerePlex Exilis is a fully digital headstage. It’s capable of pristine wireless transmission of up to 96 channels of neural data sampled at 30 kSps for up to 2.5 hours.
The CerePlex Wireless Receiver uses up to 8 antennas to acquire data from the Exilis headstage. As the animal moves, the antennas switch to ensure the strongest signal automatically. In the event wireless transmission is not available, the Exilis features a micro-USB connector to send neural data via wired transmission and re-charge the device while using. Charging the device takes only one hour.
The CerePlex Exilis’s small form factor makes it lightweight and ideal for researchers working with small, freely moving subjects.
With a flip of a switch, the CerePlex Exilis enables researchers to test impedance of the electrode while in the brain to monitor electrode tip condition. This helps troubleshoot the quality and integrity of the electrode.
