This study shows that losing a partner increases social motivation and dopamine release in prairie voles, indicating rapid adaptation in reward circuits following social loss.

The paper adapts a two-photon microscope to detect both visible and near-infrared fluorescence, enabling simultaneous dopamine and calcium imaging in the retina.

The paper uses near-infrared catecholamine nanosensors to study dopamine dynamics in meadow voles under different photoperiods, finding increased dopamine release and responsiveness in social voles.

This paper develops flexible optical fibers functionalized with SWNT-based sensors for detecting catecholamines, showing reliable performance in clinical biofluids and brain slices.

The paper develops a high-throughput method to evolve near-infrared oxytocin nanosensors for live imaging of oxytocin release in mice and prairie voles.
