Each bar is an analysis segment on the session clock (0 to 8,016 s). Blue: training (first 80% of each early segment). Aqua: validation (last 20%). Orange: test, every segment after the epoch boundary (black tick). Each natural movie appears on both sides of the boundary, so the test period is in the future and shows the same stimulus.

who and what

Areas are the Allen CCF structure at each unit’s peak channel. Probes flagged by the experimenters during an analysis segment are dropped whole, which is why some sessions lack an area.

quality control

Criteria were fixed before any model ran. Counts per criterion overlap — one unit can fail several — so the columns do not sum.
