Neuropixels probes are electrodes developed in 2017 to record the activity of hundreds of neurons in the brain. The probes are based on CMOS technology and have 1,000 recording sites arranged in two rows on a thin, 1-cm long shank. From Wikipedia
Using a read–write optical‑electrophysiology toolkit, the team mapped a top‑down feedback circuit in mice that completes missing edges in primary visual cortex.
