Continuous Attractor Network Model for Conjunctive Position-by-Velocity Tuning of Grid Cells
Figure 3
The instantaneous velocity of the traveling bumps is well described by the approximation (solid curve).
The bumps are put at 11 different positions on the velocity axis. Each circle shows the instantaneous velocity of the bumps during a 1 ms step in the one-second simulation. Overlapping circles demonstrate stable intrinsic velocity of the bumps. For the parameters used, the bumps cannot be put to positions on the velocity axis since the bumps touch the border
