Modeling Boundary Vector Cell Firing Given Optic Flow as a Cue
Figure 3
Replication of the velocity statistics of recorded rat trajectories using simulated rat trajectories.
a) The linear velocities of the rat's body motion are fitted by a Rayleigh distribution. b) The yaw-rotational velocities are fitted by a normal distribution. c) Shows the first minute of the simulated rat trajectory and d) the first five minutes of the same trajectory in a circular box (79 cm diameter). The panels e) and f) show the fits for linear and rotational velocity for a simulation in a squared box (62 cm×62 cm). The first minute and the first five minutes of the simulated trajectory are shown in g) and h), respectively.
