Modeling Boundary Vector Cell Firing Given Optic Flow as a Cue
Figure 7
Boundary vector cell (BVC) responses in a box with an additional interior wall and for a platform.
a) Square box with an additional interior wall and the occupancy of the simulated rat trajectory. b) Simulation of the BVC model using estimates from our template model. The tuning of model cells is the same as in Figure 6. c) Data of recorded BVC. Note that model and recorded BVCs respond to any wall of a certain distance and allocentric direction and not only, e.g. to the exterior walls of a box. d) Circular platform together with the occupancy of the simulated rat trajectory. For reasons of comparison we use the same trajectory as in the simulation with a circular box. e) Shows the rate map of model BVC supplied with estimates about distance and direction of walls. f) Data from recorded cells. Firing maps of BVC have been redrawn from Lever et al, J. of Neurosci. 29, 2009 from their Figure 3 on page 9774 [3].
