Microelectrode Array (MEA)

Microelectrode Array (MEA)

We use microelectrode array (MEA) to record the electrical activity of retinal neutrons. Our conventional MEA system allows the recordings of both photoreceptor and ganglion cell activity with moderate resolution (60 electrodes, electrode spacing 200µm and diameter 30µm), whereas our new CMOS-MEA system makes possible the ganglion cell recordings at the highest resolution (over 4000 electrodes with 16-32 µm spacing).
