Story summary

Researchers led by J. Nicholas Betley at the University of Pennsylvania identify brainstem Y1 receptor neurons regulating long-term pain.
These neurons integrate hunger, fear, and thirst signals to prioritize survival over pain.
Neuropeptide Y (NPY) dampens pain signals when urgent needs arise.
The study, published in Nature, suggests brain-targeted pain treatments and behavioral options like exercise and meditation.
