How does the brain represent multiple different things at once in a single population of neurons? @justfineneuro.bsky.social, @benhayden.bsky.social, B Ebitz, M Yoo, and I show that it uses semi-orthogonal subspaces for each item. Preprint here: arxiv.org/abs/2309.07766 Clouds below! (1/n)

Semi-orthogonal subspaces for value mediate a tradeoff between... When choosing between options, we must associate their values with the action needed to select them. We hypothesize that the brain solves this binding problem through neural population subspaces.... https://arxiv.org/abs/2309.07766
