Probablistic and Deterministic Reversal Learning Datasets from Rhesus Macaques from Costa et al. (2026). Amygdala and Ventral Striatum Make Distinct Contributions to Reinforcement Learning. Neuron.

This resource consists of two .mat (MATLAB) files containing flat file 2D matrices (N rows x 16 columns). deterministicRL_CostaAverbeck2016.matstochasticRL_CostaAverbeck2016.mat Each matrix contains the choice data relating to rhesus macaques performance on either a probabilistic or deterministic reversal learning task that was published in: Costa VD, Dal Monte O, Lucas DR, Murray EA, Averbeck BB. Amygdala and Ventral Striatum Make Distinct Contributions to Reinforcement Learning. Neuron. 2016 Oct 19;92(2):505-517. doi: 10.1016/j.neuron.2016.09.025. Epub 2016 Oct 6. PMID: 27720488; PMCID: PMC5074688. See Methods section of the paper for accompanying details. The column labels for each of the data tables and the coding assignments within each column are described in the two accompanying .docx files. stochastic_coding_template.docxdeterministic_coding_template.docx
