- A paper by dgclark with Larry Abbott and Haim Sompolinsky on symmetries and continuous attractors in disordered neural circuits is out in Nature Neuroscience, accompanied by a News & Views from Francesca Mastrogiuseppe and Srdjan Ostojic.
- The work addresses how brains represent continuous quantities on manifolds with nontrivial topology — head direction as a circular variable, grid cells on a toroidal manifold.
- Individual neurons forget inputs within tens of milliseconds, yet these representations persist for seconds to minutes, implying network-level collective dynamics; the paper shows how such attractors survive in disordered circuits.
