The ML870B70 System is designed for extracellular recordings from high-impedance microelectrodes that require a high gain, low noise amplifier along with the ability to inject current. The system includes a Capacitance Compensation Probe that contains the first preamplifier gain block and capacitance neutralization control on the probe itself. The voltage gain of the preamplifier is very high (50 - 10000), thereby removing the need for additional amplification between the microelectrode and recording instrument.
The system includes a PowerLab 8/30 with Chart and Chart Pro software providing sampling rates of up to 400 kHz and with the Spike Histogram Module included in the Chart Pro package provides the user with the ability to detect, discriminate and analyze extracellular neural spike activity online. Recorded spikes can also be reanalyzed offline with modified settings.
