New dopamine sensor powers three-color imaging in live animals
The tool leverages a previously unused segment of the color spectrum to track the neurotransmitter and can be used with two additional sensors to monitor other neurochemicals at different wavelengths.

Bespoke photometry system captures variety of dopamine signals in mice
The tool tracks the excitation of an engineered protein that senses dopamine’s absolute levels, including fast and slow fluctuations in real time, and offers new insights into how the signals change across the brain.

Dopamine ‘gas pedal’ and serotonin ‘brake’ team up to accelerate learning
Mice learn fastest and most reliably when they experience an increase in dopamine paired with an inhibition of serotonin in their nucleus accumbens, a new study shows, helping to resolve long-standing questions about the neuromodulators’ relationship.

Newly characterized striatal circuits add twist to ‘go/no-go’ model of movement control
The two novel pathways control dopamine release in opposing ways and may link motivation and mood to action, a new study shows.

Vijay Namboodiri and Ali Mohebi on the evolving story of dopamine’s role in cognitive function
Researchers discuss the classic stories of dopamine’s role in learning, ongoing work linking it to a wide variety of cognitive functions, and recent research suggesting that dopamine may help us "look back" to discover the causes of events in the world.

Autism researchers ‘pleasantly surprised’ by list of NIH data project grantees, despite initial concerns
An atypical funding mechanism, truncated application timeline and opaque review process had generated concern over the quality of projects that would be selected for the Autism Data Science Initiative.
