Artificial Neural Networks (ANNs) trained on specific cognitive tasks have established themselves as useful tools to study the brain, although the absence of standardized platforms and implementations still constitute important challenges. Towards this goal, we present NeuroGym, an open-source Python package that provides a large collection of carefully curated and customizable neuroscience tasks to test and compare network models. Building upon the Gymnasium platform, NeuroGym tasks (1) are imp
