(a) Biological basis features (place fields) were sampled along real rodent trajectories (b) (N=2458) in square environments in order to learn the successor matrix, $M$ (c). A representative single trial trajectory in a 100cm square (b) highlights rodent thigmotaxis and preference for corner dwelling; with 85.7% occupancy in the perimeter versus the equally-sized inner area (mean distance of animal to nearest wall=11.8cm). Once trained, successor features are formed by the matrix multiplication of $M$ with the population vector of basis features. (d) Exemplar successor features generated from rodent trajectories (left columns) closely resemble rodent subicular responses (right columns), here recorded by Sun et al. 2024.
