Dopamine Encodes Trajectory Errors Guiding Movement
|
8.3
A Boston University-led study published in Nature reports that mice exhibit a distinct striatal dopamine signal encoding real-time "trajectory errors" during visually cued navigation. This guidance signal increases when animals move toward goals, decreases when they veer off course, and scales with speed; it is spatially and temporally separate from classic reward-value dopamine. The finding could inform therapies for Parkinson’s, ADHD, and addiction.
