microwire electrode arrays are a cost-effective solution for acute and chronic extracellular neural activity recording experiments in anesthetized or awake freely moving animals. the built-in low-impedance reference electrode can effectively remove environmental noise or animal movement artifacts (chewing, scratching, etc.). water-soluble polyethylene glycol can effectively maintain the spatial arrangement of electrodes and can be used for deep brain implantation.

application scope:

1. electrophysiology & optogenetics

2. stimulation: electrical stimulation & light stimulation

3. recording signals: single cell discharge (action potential) & field potential

4. topical administration
