          Decoding Serotonin: A Comprehensive Study on Its Impact on Brain and Behavior

          Researchers conducted a detailed study on serotonin, a key molecule in influencing mood and behavior, tracing its impact from the molecular level to the brain's overall functioning. Using the simple animal model of C. elegans, the team was able to map serotonin's effects across the entire brain, giving a comprehensive view of its behavioral influence.

          Dynamic Expression of Brain Serotonin Receptors Across the Menstrual Cycle Provides Clues About Premenstrual Dysphoric Disorder

          Roughly, 3 to 8% of women suffer from premenstrual dysphoric disorder (PMDD), a disorder that causes anxiety, depression, and mood swings during the menstruation cycle. PMDD appears to increase serotonin transporter density from the preovulation phase to the premenstrual cycle phase. The findings could aid in the development of new treatments for PMDD.

          Receptor Location Matters for Psychedelic Drug Effects

          Location bias may explain how psychedelic medications work. Researchers found that engaging serotonin 2A receptors inside neurons promotes the growth of new connections, but engaging the same receptor on the outside of a neuron does not. The findings may guide the development of new psychoplastogens to treat a range of disorders including depression and PTSD.

          Why PTSD Patients Relive Highly Charged Fear Memories in Sleep

          In people with PTSD, during REM sleep norepinephrine and serotonin levels remain high, reducing the brain's ability to inhibit fear-expression neurons through neural rhythms sent between the prefrontal cortex and amygdala. Those with PTSD require higher frequency rhythms to extinguish fear memories. Researchers say unlocking the higher frequencies via therapies could help to restore quality sleep in those with PTSD.

          Study Explains Emotional ‘Blunting’ Caused by Common Antidepressants

          SSRI antidepressants can make users less sensitive to rewards, resulting in emotional blunting many users experience. The findings provide new evidence for the role serotonin plays in reinforcement learning.

          How Serotonin Genes and SSRIs Can Contribute to Heart Valve Disease

          Taking SSRIs and having the "long-long" serotonin SERT genetic variant lowers SERT activity in the mitral valve, leading to degenerative mitral regurgitation, one of the most common heart valve diseases.

          Good and Bad Feelings for Brain Stem Serotonin

          A newly identified serotonin pathway that originates from the median raphe nucleus acts in opposition to the reward/aversion pathway in the nearby dorsal raphe nucleus. The findings could pave the way for the development of new treatments for major depression, addiction, and other disorders associated with serotonin.
