Functional MRI of large scale activity in behaving mice

This paper develops an fMRI approach for whole-brain activity recording in behaving mice, demonstrating its use in complex tasks and reducing movement artefacts.

The Long and the Short of Serotonergic Stimulation: Optogenetic activation of dorsal raphe serotonergic neurons changes the learning rate for rewards

This study shows that optogenetic activation of dorsal raphe serotonin neurons in mice increases learning rates for rewards after long inter-trial intervals based on recent reinforcement history.

Activation of dorsal raphe serotonergic neurons promotes persistent waiting independently of reinforcing effects

This study shows that activating dorsal raphe serotonergic neurons increases mice's ability to wait for delayed rewards without affecting appetitive or aversive responses.
