LARGE-SCALE RECORDING FROM AXONAL ARBORS OF SINGLE NEURONS WITH CMOS BASED HIGH-DENSITY MICROELECTRODE ARRAYS

We report on the identification and tracking of the electrical activity of processes of single neurons. With a newly designed complementary metal-oxide-semiconductor (CMOS) based integrated highdensity microelectrode array (HD-MEA) [1,2], we were able to simultaneously use more than 1000 electrodes and low-noise readout channels to monitor electrophysiological signals of many individual branches of a single axonal arbor of a specific neuron.
