Multichannel arrays with integrated optical fibers (MicroProbes)
MicroProbes - Optogenetics Electrode Array / Opto-MEA
Description

 

With MicroProbes' novel and reliable products the photoactivation/photoinhibition of cells through an integrated optical fiber combined with multichannel arrays allow you to achieve neural electrophysiological recording of an extended brain area in parallel with photostimulation.

 

Features

The fiber optic is positioned in the middle of the array, its vertical position is custom and its receptacle is compatible with most of the light sources.

 

Photoexcitation and -inhibition

The small-scale but high-density arrays provide multichannel Single-Unit (SUA), Multi-Unit (MUA) and Field Potential (FP) data leading to consistent and high-quality results.
