This paper introduces NeuraGEM, a neural architecture that models online discovery of latent contexts through fast transient activity and slow synaptic plasticity, reproducing human contextual learning features and brain-like dynamics.

This study shows that episodic memory stabilizes task representations, enabling structured knowledge accumulation in a neural network model.

This study uses fMRI and dynamic causal modeling to show that ventromedial prefrontal cortex (vmPFC) modulates connections from dorsolateral PFC to orbitofrontal cortex based on prior belief during decision strategy re-evaluation.
