This study shows that timing of dopamine release from VTA to mPFC during specific delay periods modulates working memory performance in mice.

This study shows that reducing CB1R signaling in the VTA decreases sign-tracking behavior and alters cue-outcome dopamine dynamics in the NAc of rats.

This study examines dopamine signaling in the dorsal bed nucleus of the stria terminalis during Pavlovian learning and reward violations, revealing strategy-dependent patterns of dopamine responses.

This study uses a genetically encoded dopamine sensor to measure dopamine release in the nucleus accumbens during social behaviors in mice, revealing distinct patterns in different phases of social interaction.

This study shows that dynamic dopamine signaling over seconds predicts movement initiation timing in mice by modulating the probability of movement on a trial-by-trial basis.

This study demonstrates that ramping dopamine signals correspond to reward prediction errors rather than state values, unifying rapid phasic and slow ramping signals as derivative-like computations.

The paper identifies a brain circuit from the superior colliculus to the substantia nigra pars compacta that enhances appetitive locomotion during predatory hunting by modulating dopamine release.

The paper develops and optimizes GRABDA fluorescent sensors to monitor dopaminergic activity with high sensitivity and resolution in vivo.

This paper develops GRABDA sensors to measure dopamine with high precision in multiple organisms during complex behaviors.
