🔬 Study in iScience shows confinement stress reduces male fruit fly courtship. This effect lasts longer when dopamine signaling is altered.

⏳ Short confinement (10 min) had no impact, but 30-60 min severely reduced courtship, with effects lasting up to 4 hours. Longer stress (7-24 hrs) suppressed behavior for at least 5 days.

🧠 Dopamine is key to maintaining the stress-induced reduction in mating drive. Blocking dopamine production or release temporarily prevented the sustained suppression of courtship behavior.

🎯 Specific dopamine receptors (Dop1R1, Dop2R) in the mushroom body, and signals from PAM/PPL1 neurons, are crucial for the persistent stress response.
