Catalog Number: 40-43-1
Built in impedance check circuit with digital display and audio amplifier with a noise filter have been added to our single channel microelectrode amplifier for extracellular recording which features sharp, adjustable high and low cutoff filters, a notch (line) filter, as well as gain to x100,000. Also includes a switchable input to permit stimulation or lesion currents to the recording electrode.
Provided with metal and glass microelectrode holders which plug into the high impedance probe built into a stereotaxic holder.
The 40-43-1 Microelectrode Amplifier represents a new standard of low noise, high impedance amplification versatility for extracellular applications. State-of-the-art integrated circuits have enabled us to lower noise while increasing band width, while, at the same time, adding features that make microelectrode recording more convenient. By connecting a high impedance, low noise, differential preamplifier directly to the electrode carrier, external noise pickup is minimized. A convenient, plug-in holder for metal microelectrodes is included with the system. The probe has been designed to be used with other physiological electrodes as well. A wide range of low and high cut-off filters allows the investigator to reject signals outside the bandwidth of interest. Additionally, a sharp notch filter can be introduced to virtually eliminate interference from power lines. With a voltage gain adjustable from 10 to 100,000 in thirteen calibrated steps and a wide dynamic output range of +10V, the Xcell 3+ can be interfaced with any data collection or storage system.
