Prefrontal Cortex Can Block Creative Problem-Solving

Summary: Researchers discovered an unexpected role for the medial prefrontal cortex (mPFC), a region traditionally viewed as the executive driver of behavioral flexibility. The team demonstrated that the mPFC can…

Why Psychedelics Make Everything Feel Deeply Connected

Summary: Researchers introduce “apical hypercontextualisation”—a bottom-up neurobiological mechanism explaining how psychedelics (psilocybin, LSD, DMT, mescaline) transform perception and cognition. Moving beyond macro-scale whole-brain neuroimaging, the framework focuses on the cellular…

Early Stress Heightens Adult Anxiety

Summary: Researchers uncovered a fundamental epigenetic mechanism explaining how early-life adversity permanently alters the brain’s stress response networks. The study identified that childhood trauma increases levels of the enzyme SETD7…

Peripheral Blood Cells Replenish Aging Human Microglia

Summary: Researchers revealed that aging leads to a massive, previously unrecognized migration of peripheral blood stem cell-derived immune cells into the human brain. The team dismantled the long-held dogma that…
