Dorsomedial striatal dopamine ramps down during interval timing

The paper investigates dopamine dynamics in the mouse dorsomedial striatum during interval timing and finds that dopamine ramps down before reward delivery, predicts timing behavior, and varies between sexes and with amphetamine.

Diverse activity in prefrontal projections promotes temporal control of action

The paper investigates prefrontal projections during interval timing, finding distinct temporal coding and transcriptomic profiles in PFC-MD and PFC-DMS circuits.

Complementary cognitive roles for D2-MSNs and D1-MSNs during interval timing

This study shows D2-MSNs and D1-MSNs have opposing dynamics but complementary roles in interval timing, revealing how striatal pathways contribute to cognitive timing.

Amphetamine increases timing variability by degrading prefrontal ramping activity

This study shows amphetamine increases timing variability by reducing prefrontal cortex ramping activity and neural interactions in mice.

Sex similarities and dopaminergic differences in interval timing

The paper investigates sex differences in interval timing across humans and rodents, finding no sex differences in timing accuracy or precision but distinct dopaminergic effects in males.

Quantifying the inverted U: A meta-analysis of prefrontal dopamine, D1-receptors, and working memory

This study performs a meta-analysis of prefrontal dopamine and D1-receptor manipulations on working memory, finding a negative quadratic relationship explaining 10% of variance.
