In male mice, tonic dopamine transmission in the medial preoptic area (MPOA) declines after successful mating and re-emerges over a week, paralleling recovery of mating drive.
- Why it matters: Motivation can shift over many days, but the neural slow-timescale rules linking dopamine dynamics to recovery of drive are unclear.
- What they did: Using deep-brain fluorescence-lifetime imaging in the MPOA during mouse mating, the study tracked tonic dopamine transmission and tested two contributors: transient changes in hypothalamic dopamine neuron firing and a post-mating drop in dopamine production/release capacity.
- The result: Mating suppressed tonic firing for 1 to 2 days and reduced dopamine production/release, which recovered over the following week, enabling recovery of motivational drive across days.
