This paper introduces ultrasound-mediated neuromodulator delivery to study serotonergic control of context-dependent motivation in primates, showing altered neural activity and reduced reward environment influence.

The paper uses interpretable neural network models to predict human information gathering behavior and identifies brain regions involved in value of information processing.

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 uses computational modeling and EEG/ERP data to compare neural dynamics of self-initiated and externally triggered actions, finding distinct preparatory patterns in prefrontal areas.

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

The paper identifies common neural patterns associated with task engagement and disengagement in macaques using fMRI, showing causal links to specific brain regions.

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.

The paper identifies asymmetric reward-related activity in the orbitofrontal cortex of humans and rhesus macaques and links it to functional connectivity asymmetry.

The paper investigates neural precursors of self-initiated actions by comparing EEG variability before self-initiated and externally-triggered actions, finding stronger convergence during deliberative planning.

The paper investigates the neural processes preceding self-initiated actions by comparing EEG variability in self-initiated versus externally-triggered skip responses, finding reduced neural noise prior to self-initiated actions.
