Optogenetic Arrays / MWA
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.
Designed for chronic experiments, the Microprobes Optogenetics Microwire Array (Opto-MWA) provides the optimum in flexibility and affordable alternative for the neuroscience community.
Features
- Multiple optical fiber diameter available.
- Up to 32 penetrating wires per array for short- and long-term recording.
- Custom wire length (5 - 23 mm), including different length for each row.
- Custom spacing between electrodes is in the range of 0.1 - 1 mm
- Custom spacing between wires is in the range of 250 - 1000 µm.
- Custom wire diameter options available (25 / 50 µm).
- Impedance options between 200-800 kΩ.
- Stainless Steel and Platinum/Iridium fine wires teflon or polyimide insulation material.
- Custom reference and ground electrode according to the researcher's requirements.
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.
