Features:

Extracellular Amplifier

• AC/DC differential amplifier
• High input impedance, Z (10¹² Ohm typical)
• Excellent common mode rejection, CMR (120 dB @ 60 Hz)
• High DC tolerance which allows amplification at the input of microvolt extracellular action potentials that are accompanied by much larger DC electrode voltages (±2 V DC)
• High gain with gain selections at x10, x100, x1000 and x10000
• Low noise & bandwidth filtering (typically 8 µV p-p at 1 Hz to 10 kHz bandwidth)
• Small active headstage which can be mounted in micromanipulators
• Suitable for use with high impedance glass or metal microelectrodes
• Internal Calibration signal provides easy checking of amplifier gain and operation

Data Acquisition System and Analysis

The PowerLab 8/30 is shipped with ADInstruments software (LabChart and Scope), associated manuals and cables. The system is also supplied with LabChart Pro software which includes all the ADInstruments LabChart Modules (excluding GLP). LabChart Modules provide application specific data acquisition, analysis and display features. The modules currently available include:

• Circadian Analysis (Windows)
• Dose Response (Windows)
• Peak Analysis (Windows)
• Blood Pressure (Windows)
• ECG Analysis (Windows)
• Heart Rate Variability (Windows & Macintosh)
• Spike Histogram (Windows & Macintosh)
• Metabolic (Windows & Macintosh)
• Video Capture (Windows & Macintosh)
• Cardiac Output (Windows)
• DMT Normalization (Windows & Macintosh)

LabChart Pro entitles the purchaser to 5 years of FREE LabChart Pro software upgrades and updates. Purchasers are also entitled to any ADInstruments modules released during this 5 year period (excludes GLP software).

For more information see the LabChart Pro page or contact your nearest ADInstruments representative.

Applications:

This Extracellular Recording System allows recording of EEG, ECG and extracellular recording with the DP-311 Differential Amplifier with Active Headstage using glass or metal microelectrodes. Extracellular recordings include:

• Single Unit Recording – records the electrical activity of a single one neuron with a small tip electrode 
• Multi-Unit Recording – records electrical activity generated by several neurons
• Field Potentials - records the field potential generated from indistinguishable activity generated by many cells
• Amperometry-records changes in the chemical composition of the oxidized components of a biological sample using a carbon electrode

For more information see the Extracellular Recordings and Neurophysiology application pages.
