Study first to pinpoint why analgesic drugs may be less potent in females than in males

... likely due to sex differences in mu-opioid receptor expression in a region of the brain called the periaqueductal gray area (PAG). Located in the midbrain area, the PAG plays a major role in the modulation of pain by housing a large population of mu-opioid receptor expressing neurons. Morphine and ...

Caltech scientists engineer supersensitive receptor, gain better understanding of dopamine system
