Self-organization of grid network in a continuous attractor model Roudi group: Couey et al., 2013; Bonnevie et al 2013 Y. Roudi & speed Then, when the activity bumps are translated across the network in accordance with the animal’s movement, using speed and direction signals, it will yield grid fields in individual cells.
HALF A CENTURY HAS PASSED AND TOLMAN´S MAP HAS BEEN ´PHYSIOLOGIZED´ “Today, however, I believe that this (physiologizing) is where the great new breakthroughs are coming..” E.C. Tolman (1958) SUMMARY • Grid cells define hexagonal arrays that tessellate local space. • Grid modules are organized in anatomical space. • Grid cells cluster discontinuous modules. • The intrinsic functional organization of a grid module is preserved across environments. • Fine-scale grid-cell architecture can be investigated with 2-photon calcium imaging. • Grid cells may be generated by attractor networks.
