A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.
The effect presumably comes from the absence of S-cones in the fovea.

Lots of very serious people are working on how to share big datasets across archives and rigging up all sorts of cloud proxy systems and bridges and whatnot and I am here to tell you that torrents with multiple webseeds have already solved that problem

Super excited to share that our new study is published @natneuro.nature.com today!! Here we show that intersectin and endophilin form condensates between the active zone and the reserve pool and maintain synaptic vesicles near the active zone for rapid replenishment.
