Abstract :
A CMOS sensor array for extracellular, high density imaging of electrical activity of living neural networks is presented. The chip is fabricated in an extended 0.5 μm CMOS technology, and provides 128 × 128 pixels with a pitch of 7.8 pm; full frame rate is 2000 frames per second. Dynamic maps from single cells and cultured networks are shown.
