The static distillate gains a time axis: a hippocampal write-gate that only encodes novelty, consolidation from ephemeral buffer to persistent hemispheres, and an amygdala tagging the heaviest brakes.
THE CORRECTION FIRST. The hippocampus is not the anger center — that is the amygdala, and even that is a simplification. Alligators possess a hippocampus; the "reptile brain" triune model is discredited. So v2 adds what the structure actually does: it is the encode-gate for new memory. The v1 cortex could hold the corpus but never learn one — it had no clock. This is the clock.

2D · the hippocampal relay (center) gates writes into the two hemispheres; novelty stream at top, consolidation buffer shown filling; amygdala flags ring the flagged brakes
LOAD · hippocampus ≈ 0.5% of brain volume, gates ≈ 100% of new declarative memory → 200× throughput-to-size, the busiest bottleneck in the system. Lesion it (patient H.M.) and every existing memory survives while no new one can ever form. Its load is not storage — it is the encode gate, and it carries all of it.
3D · 30 cortical nodes in two hemispheres + the central hippocampal relay (purple) wired to all three EPL bands + the amygdala (red) tagging the 4 flagged brakes. Drag to rotate.
Diagnostics — v2 wiring re-verified at load
TODDLER CORNER
The brain-crystal from last time couldn't learn anything new — it was frozen. We added the part that makes new memories: a little gatekeeper in the middle. It only lets in things it hasn't seen before (old news gets a shrug), and it can only carry a few at a time before it has to rest and file them away. It's tiny but the busiest part of the whole brain. And no — it's not the angry-alligator part. That's a different piece, and we added a small version of it too, just to tag the scariest stories.
