Representational similarity modulates neural and behavioral signatures of novelty: Model simulations

Here, we provide model simulation data accompanying the analysis of neural and behavioral data in our article 'Representational similarity modulates neural and behavioral signatures of novelty'. This data set contains (i) simulations of similarity-based novelty models for fitting of V1 novelty responses: grid_search_results.zip (ii) simulations for parameter robustness analysis of similarity-based novelty, fit to V1 novelty responses: gridsearch_robustness_width.zip (iii) simulations of novelty-RL agents with similarity-based novelty, fit to mouse exploration behavior: ppc.zip The code used to generate the simulated data as well as further description of the data set are available at: https://github.com/sobecker/sim_nov.
