CEREPLEX A headstage Endless flexibility with neural recording.

Endless flexibility with neural recording

CerePlex A is a high-channel, low-noise, quasi-DC amplifier designed for simplicity, flexibility and miniaturization. It is Blackrock Microsystems’ next-generation, digitizing amplifier for interfacing neural electrodes directly (macroelectrodes), or via analog headstages (microelectrodes), to any Blackrock data acquisition system.

The amplifier features flexible, analog-reference electrode selection for optimal removal of environmental noise and artifacts prior to analog-to-digital conversion. Quasi-DC operation enables recording of distortion-free signals down to near DC. The integrated, electrode-impedance measurement facilitates interrogation of Blackrock Microsystems or third-party electrodes.

For experiment designs that include electrical neural stimulation, CerePlex A’s fast-settle circuit ensures high-quality neural recordings immediately after stimulation.

CerePlex A features & benefits

  • Up to 128 channel neural inputs
  • Quasi-DC recording
  • Ideal for experiments designed for neural stimulation
  • Direct interface with any neural electrode
