Motion sensing, at 1 gram
CerePlex µ
The CerePlex µ is a very small and lightweight digital headstage that provides a platform for simple stimulation and tracking in freely moving rodents. It provides an interface between the Cerebus™ or CerePlex™ Direct recording systems and up to 32 microelectrodes for high-fidelity transmission and recording of extracellular spikes and local field potentials from the brain. In addition to neural recording, it features an onboard accelerometer and gyrometer as new tools for monitoring animal behavior.
Match neural recordings to movement using onboard 6-axis motion sensor band and don’t be fooled by artifacts. The CerePlex µ enables the detection of a variety of subtle movements and behaviors, with high temporal precision, such as:
- Freezing and anxiety
- Grooming
- Rearing
- Movement initiation/termination within operant tasks
- Circadian rhythms
- Disease states (turning, shaking, etc.)
CerePlex µ features & benefits
- Small size
- Light weight
- IR LED for tracking
- 3D accelerometer and gyroscope
- on-board impedance testing
