IBIS Instrumentation Canada is pleased to announce its exclusive distributorship in Canada for Alpha Omega Engineering, the Israeli developers and manufacturers of a complete family of modular setups for extracellular recording.

Use of this state-of-the-art equipment has many advantages. Consider the following:

EPS and MT
manipulates a large number of extracellular microelectrodes simulaneously and independently to record activity from the nervous system.

Modular, Flexible and Compact
Begin with a small number of electrodes and upgrade easily to more than 16 channels. Testing from different areas and angles of the brain simultaneously is a huge benefit due to its modularity, flexability, and compactness. Since each electrode can be manipulated individually, you have the optimum ability to ensure the best recording results.

High Resolution, Long 
Working Distance
The EPS has a long working distance of 40mm and a resolution of 1 µm. This enables you to reach any brain location, even in large animals, and place the electrode exactly in the desired position to achieve optimum recording conditions

MT: Microdrive Terminal
for holding and initial positioning of the microelectrodes

This device, placed on the animal skull, holds the microelectrodes, and connects them via the flexible shafts to the EPS (see figures at right). One MT can handle up to 8 electrodes. The base consists of a XY manipulator table (see detail photo at right), which allows 16 mm movement in each direction. The initial depth of the electrodes can be set by a Z-axis adjustment knob (40 mm movement). A further 40 mm of depth control with a resolution of 1 µm can then be obtained by use of the EPS.

Overview of a full setup. Two Micromanipulators, connected via flexible shafts to two Microdrive Terminals, mounted on a perspex dome (representing the animal's skull).

EPS Windows Software
User-friendly software (running under Windows 3.11 or Windows 95) gives greater control and flexibility...just click the mouse to apply a command on one or several electrodes. This applies to grouping, positionings, and moving of the electrodes.

Modular, 8-250 Channels
Rather than buy several systems for numerous channels, save your budget and lab space by having one modular system that can handle 16-250 channels. The MCP-Plus comes with a minimum of 16 channels. More channels can be added in multiples of 4.

MCP-Plus 8, 8 Channels is a non-modular 8-channel amplifier and signal conditioner.

500 Gain Selections

No matter how large or miniature the signal, with 500 applicable gains, you can select the best amplification for the signal.

Low Pass, High Pass Filters
Regardless of the bandwidth of the signals, with hundreds of high and low pass filter selections, you can choose the optimum filtering.
The task of controlling and setting the parameters for many channels is made easier with this user-friendly software that runs under Windows.
