Study identify 2 key neurotransmitters at different phases of sex. In male mouse brains, acetylcholine is released up to insertion of penis into vagina. Dopamine and acetylcholine then oscillated in brain with mouse’s thrusting motions. On ejaculation, dopamine release slowed before rising quickly.

Dopamine neurons—the cells that drive reward & motivation while we’re awake—become surprisingly active during nonrapid eye movement sleep 💤 right after we learn something new. This night surge 🌙 that helps strengthen motor memories 🏃‍♂️ and improves motor skills, according to a new U-Michigan study.

🧠 New CU Boulder research reveals dopamine's key role in "a skip in your step" when happy. Scientists found that unexpected rewards can boost movement speed, offering insights into conditions like Parkinson's and depression.

💡 An experiment showed subjects moved faster towards rewarding targets. Surprisingly, an unexpected reward during a reach actually sped up their motion, suggesting a "second jolt" of dopamine.

📈 Past experiences also influence movement speed: consistent rewards lead to faster overall movement, while bad luck causes slowing down, reflecting the brain's reward prediction learning.

🧠 New study in mice reveals dopamine receptors on support cells act as "traffic signals" for migrating neurons, slowing them down to reach correct destinations. Disruptions to this signaling early on could permanently alter brain wiring.

🔬 Researchers found that removing dopamine receptors from stationary cortex cells caused migrating neurons to speed up significantly, overshooting their targets and leading to abnormal brain structure in adult mice.

📉 In mice lacking D1 dopamine receptors entirely, the cerebral cortex volume shrank by about a quarter, demonstrating the critical role of dopamine signaling in early brain development.

🧠 UC Irvine researchers have discovered that a loss of dopamine in a key brain region drives memory loss in Alzheimer's disease.

💊 Restoring dopamine levels, including with the drug Levodopa, improved memory function in preclinical models, suggesting a new treatment pathway.

📅 Findings were published on April 23, 2026, in Nature Neuroscience.

Dopamine dictates how long sexual drive remains suppressed after stress

🔬 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.

🧠 Study in Nature reveals biological transition to motherhood causes lasting molecular brain changes, driven by dopamine, enhancing learning and memory.

🔬 Chronic stress after birth can disrupt these natural neurological adaptations, impacting maternal brain remodeling.

💡 Research suggests the postpartum period is a sensitive window for cementing these changes, and external stressors can block this process.

🧬 Findings in mice translate to human brain tissue, showing similar molecular patterns of motherhood and the impact of dopamine signaling.

🧠 A study in eBioMedicine found that long COVID patients have a measurable reduction in dopamine-releasing neurons, linked to symptoms like apathy, memory issues, and slowed movement.

🔬 Researchers used brain imaging on 24 long COVID adults, finding an average 18% loss of dopamine nerve terminals in key brain regions. Lower levels correlated with apathy, memory problems, and slower motor speed.

💡 These findings suggest that treatments targeting dopamine function could be a new therapeutic approach for the neurological symptoms of long COVID.
