ACC representations of reward-driven motivation over hierarchically-organized behavior.

ABSTRACT: The neural mechanisms of reward-guided behavior have been researched extensively but how rewards affect the neural processes underlying the production of hierarchically-organized sequential behaviors remains unclear. In particular, anterior cingulate cortex (ACC) is said to motivate the successful completion of hierarchically-organized tasks by grouping together low-level actions according to superordinate goals, which are encoded across ACC neural ensembles as distributed, multivariate representations (Holroyd & Verguts, 2021; Holroyd & Yeung, 2012). Here we applied model-based representational similarity analysis (RSA) to investigate how rewards modulate these representations. We adapted an existing recurrent neural network (RNN) model of ACC activity (Colin et al., 2024) to predict the
