Microwire Array

Microwire Arrays (MWAs)* are most commonly used in chronic, freely moving animal studies. They are easily customizable, well-constructed, and appropriate for large and small animals. MWAs are popular due to both their recording reliability and cost efficiency. Additionally, they are compatible with any Plexon headstages that utilize Omnetics connectors.

MWAs can be customized in many ways with choices for electrode number, configuration, spacing, materials, insulation, lengths, diameter, and connectors amongst other options. The wires are crafted using stainless steel or a platinum/iridium alloy to be durable; yet, cost effective enough to be disposable. Dissolvable polyethylene glycol (PEG) secures the wires’ spatial arrangement, which ensures the electrodes remain straight and maintain their parallel position within the array while advanced into the tissue. This stability in design is particularly important when targeting deep brain structures. All MWAs come with optional ground and low-impendence reference wires that, when used with Plexon headstages and preamplifiers, assist with common-mode rejection and removal of artifacts.

To enhance your experience, control and results when using MWAs, we offer a breadth of compatible, high quality connectorsheadstagesheadstage cables, and commutators. You may also wish to explore other options in Plexon’s family of specialty electrodes, probes and arrays including the Floating Microelectrode ArrayU-Probe, or the advanced Thumbtack Probe.

This made-to-order MWA is the standard choice for hundreds of research labs around the world performing chronic, freely moving animal studies. Your Plexon Sales Engineer is happy to provide additional information and to assist you in determining what might be the most advantageous MWA configurations to achieve the most from your research.
