Agent and arena parameters
| Parameter | Value |
|---|---|
| Dwell time | 4 s |
| Linear velocity | [25, 35] cm/s |
| Angular velocity | [100, 720] °/s |
| Circular arena dimensions | Radius 50 cm |
| Rectangular arena dimensions | 150 × 50 cm |
| NPC (circular) | 4 × 4 |
| NPC (rectangular) | 6 × 2 |
| IVIS amplitude | 2.5 nA |
| σIvis (scaling) | max (50, 4 ∗ NRF) |
NPC refers to the number of place cells for a given arena. Linear and angular velocities are sampled uniformly across the indicated intervals for each turning and linear trajectory event (i.e., once between target locations in the arena). The IVIS amplitude refers to the peak value of the Gaussian current profile, which is derived from the visual system of the agent model, and injected into Vis. σIvis refers to the variance of the Gaussian current profile, with NRF indicating the number of receptive fields covered by the salient landmark.
