HectoSTAR microLED optoelectrodes for large-scale, high-precision in invo opto-electrophysiology

We present a device that can be utilized for a large-scale in vivo extracellular recording, from more than 250 electrodes, with the capability to optically modulate activities of neurons located at more than a hundred individual stimulation targets at the anatomical resolution. ### Competing Interest Statement The authors have declared no competing interest.
