Every dot is one action potential

1,745 neurons, recorded simultaneously for 30 seconds, sorted with Kilosort 4 and filtered to units with a firing rate above 0.1 spikes/s, an amplitude above 50 µV, and a clean refractory period.

Subject KM_077, 24 May 2026. Color marks the probe — teal, salmon and gray — and the four shades within each mark its four shanks. Neurons are ordered by probe, then shank, then depth, so scrolling walks down one shank at a time from the surface of the brain to 5,149 µm. Probe 00 was drift-corrected with DREDge before sorting.
