Low noise from start to finish
CerePlex M
The CerePlex M is a small, lightweight digital headstage. It provides an extremely low-noise, 7-wire, all-digital link from up to 128 neural microelectrodes to the Cerebus data acquisition system. The onboard digitization circuitry of the CerePlex M eliminates artifacts due to headstage cable motion and environmental noise pick¬up. Its multiplexed output allows the researcher to use a single lightweight cable instead of multiple bulky cables. It also eliminates the need for an expensive motorized commutator when recording from freely behaving small animals such as rats, mice and birds.
CerePlex M features & benefits

- Miniature and lightweight
- Eliminates artifacts from cable motion and environmental noise
- Spike and field-potential recording
CerePlex M applications
- Freely behaving small animals
- Head-free, non-human primates
