EEG Test May Reveal Who Loses Libido on Antidepressants
Summary: A new study reveals that serotonin levels in the brain, measured using a simple EEG-based test, can predict who will experience sexual side effects from SSRI antidepressants. Researchers found…
Sugar Chains in the Brain: New Pathway Behind Depression Found
Summary: Scientists have discovered that depression can be driven by abnormal sugar modifications on proteins in the brain, offering a new molecular pathway for understanding the disorder. Chronic stress was…
Prozac May Rewire the Brain by Loosening Rigid Neural Circuits
Summary: A new study shows that fluoxetine, better known as Prozac, does more than increase serotonin—it changes how brain cells handle energy and rebuild connections. After two weeks of treatment,…
Why religious groups are pushing for psychedelics as sacrament
Texas passed a landmark law in June 2025, supported by former Gov. Rick Perry, that allocates US$50 million to support research on ibogaine, one of the most powerful psychedelics, for…

More Than Serotonin: How Psychedelics Engage the Whole Brain
Summary: Classical psychedelics like LSD, psilocybin, and mescaline are known for activating the 5-HT2A serotonin receptor, but a new study reveals their effects go far beyond. Researchers profiled 41 psychedelics…
Low Sodium Linked to Anxiety Through Brain Chemistry Disruption
Summary: Chronic hyponatremia—long viewed as symptomless—is now shown to disrupt brain chemistry and cause anxiety-like behaviors, according to a new study in mice. Researchers found that prolonged low sodium levels…
How Serotonin Circuits Learn from Motion to Regulate Behavior
Summary: Scientists have uncovered how serotonergic neurons in larval zebrafish process visual information tied to movement to determine when and how much serotonin to release. This neuromodulator fine-tunes the fish’s…
