Blackrock offers a wide range of headstages for recording distortion-free spikes and field potentials from high-impedance microelectrodes. The headstage provides an isolated low-impedance output that guarantees signal integrity, minimizes noise pickup by cables (as long as 3 m), and ensures maximum common-mode noise rejection by the Cerebus system front-end amplifier. Configurations are available for attaching to freely-moving or restrained animals as well as slice or cell-culture preparations.
