ACh-modulated predecessor feature learning enables post-reward exploration

Our paper, “Eligibility-trace–gated depression in predecessor feature learning enables post-reward exploration,” has been published.

In this study, we propose an acetylcholine (ACh)-modulated predecessor feature learning model and investigate how it can support flexible exploration even after reward acquisition.
