🧠 Cool new study by Tafazoli et al. (2026) 👏: The brain reuses lowdim #NeuralSubspaces across tasks. Sensory features and #MotorActions share population #subspaces, enabling flexible task switching via belief updates and routing.

In a von Neumann algebra, a projection E satisfies two properties:

#Self-adjoint (E = E*).
#Idempotent (E = E²).
Geometrically, projections map vectors onto closed #subspaces of a #Hilbert space, with the subspace being the "range" of E.
