Semi-Chronic Recording System

The Semi-Chronic Recording System is a microelectrode recording system for:

• Restrained or partially restrained animals
• Minimizing brain movement in acute preparations while still exposing a wide area for depth or surface recording
• Maintaining and monitoring brain temperature during acute experiment 

Artifact Suppressor Diff Input

The Artifact Suppressor Module provides a convenient method for eliminating artifacts produced by electrical stimulation.

Audio Analyzer

The Audio Analyzer has two circuits to aid the electrophysiological investigator searching for cells. For extracellular recordings, EDG, or EEG, the Audio Analyzer provides an audio amplifier circuit with adjustable frequency response and wide volume range. These features permit "tuning in" to the correct frequency signal. A noise filter is included for reducing the hash from the signal.

bp Optical Isolator with Probe

Our bp Isolator provides the electrophysiologist with the means to deliver isolated bipolar or other complex waveforms, in either constant current (50mA maximum) or voltage (±140V maximum) modes.

DC Temperature Control System

The DC Temperature Control System is a feedback based system for monitoring and maintaining subject or bath liquid temperature.

Dual Notch Filter

The Dual Notch Filter has been designed to eliminate troublesome 60Hz pick-up and 120Hz ground loop noise in electrophysiological recording set-ups.

ECM Experiment Control Module

The Experiment Control Module (ECM) provides a hardware solution for coordination of all instrumentation in any stimulus-response setup.  Interfaces with MATLAB and Visual Basic using ActiveX integration.

HiZx8 8-Channel Differential Amplifier

Eight channel extracellular includes sharp, adjustable high and low cutoff filters, a notch (line) filter, and gain to x100,000. Features probe which can be mounted near recording site to minimize pick-up noise.

Hydraulic Probe Drive

Miniature hydraulic probe connected to a master cylinder by 3m (other lengths optional) tubing allows discrete micro dimension movement of microelectrodes as well as minimizes vibration and audio artifacts. Sealed hydraulic system never needs refilling and has 15mm travel. Stereotaxic or chronic head mounting options are available.

The hydraulic system can be driven with either of two micrometer drives or with a motorized drive which features a one micron digital display module, handheld remote control (2 options) and a motor coupling unit which can be positioned large distances from the control module if required.

ICM Impedance Conditioning Module

The ICM Impedance Conditioning Module measures impedance, capacitance, and resistance in a single sweep, which can be used to verify metal microelectrodes, glass micropipettes, and to troubleshoot recording setups.

Microchronic Recording System

The Microchronic Recording System has been designed to permit microelectrode stimulating or recording in awake, unrestrained small animals. The System is small enough to be implanted on 300g rats yet provides access to position the microelectrode in a 2.5mm diameter tissue volume.

Microelectrode Multidrive

The advantages of hydraulic coupling of microelectrode movement can now be extended to 4 and 8 channel systems allowing independent movement of each microelectrode along parallel or nonparallel tracks. Unique manifold concept also permits customization of electrode grid arrangement. Variety of microelectrode types can be accommodated.

OTS-5000 Tissue Slicer

The OTS5000 Tissue Slicer sections fresh tissue slices in user defined "travel window" and reduces blade travel time between sections. Slicer head design minimizes vibration that causes tissue distortion. (<20 micron Z movement).

StimPulse Stimulator

The neuro/Craft™ StimPulse Electrical Stimulation System is comprised of two devices, the PGM Pulse Generator Module and the ESG Electrical Stimulus Generator, that deliver isolated electrical stimulation in a wide range of user-defined timing and pulse parameters.

Xcell-3+ MicroElectrode Amp

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.

Xcell-3 Microelectrode Amplifier

Single channel microelectrode amplifier for intracellular and extracellular recording features sharp, adjustable high and low cutoff filters, a notch (line) filter, as well as gain to x100,000. Also includes a unique artifact suppressor circuit, a switchable input to permit stimulation or lesion currents to the recording electrode, and a x10 DC output.

Provided with metal and glass microelectrode holders which plug into the high impedance probe built into a stereotaxic carrier.
