This study challenges the idea of anterior dominance in primate prefrontal cortex by showing posterior dominance in task-related signals and frontopolar deactivation in macaques.

The paper investigates optimal information loading into working memory in prefrontal cortex using mathematical analysis, simulations, and monkey recordings, finding orthogonal inputs lead to dynamic coding.

This study shows that frontal cortex neurons in monkeys exhibit a binary one-shot switch between explore and exploit behaviors during a task with a known structure, rather than continuous changes linked to prediction errors.
