This paper proposes that dopamine ramps result from a dual-process learning system and demonstrates that the model reproduces key dopamine ramp phenomena.

The paper shows that human dorsal raphe nucleus activity signals changes in behavioural policy based on environmental reward value, while dACC and AI track relative reward value.

This study improves functional MRI analysis in awake non-human primates by applying dynamic off-resonance correction, enhancing image fidelity and activation estimates.

This study shows that the dorsal raphe nucleus (DRN) in monkeys influences transitions between high and low motivation states based on reward availability.

The paper identifies a subcortical circuit involved in switching between threat vigilance and reward foraging in humans using fMRI.
