How the Prefrontal Cortex Suppresses Creativity
Summary: Researchers have identified an unexpected role for the medial prefrontal cortex (mPFC). Rather than always promoting behavioral flexibility, this brain region…
Exercise Protects Dopamine Neurons in Parkinson’s Disease
Summary: This review synthesizes evidence from 129 studies examining how exercise-induced muscle signaling protects against Parkinson’s disease (PD). It highlights the role…
Why Psychedelics Create a Sense of Oneness
Summary: Researchers propose “apical hypercontextualisation,” a cellular-level neurobiological mechanism that explains how classical serotonergic psychedelics—such as psilocybin, LSD, DMT and mescaline—reshape perception,…
How Receptor Density Shapes Whole Brain Network Dynamics
Summary: Researchers have created a biologically grounded whole‑brain computer model that links microscopic molecular chemistry to macroscopic neural activity, demonstrating how regional…
Childhood Stress Raises Risk of Anxiety in Adulthood
Summary: Researchers have identified a concrete epigenetic mechanism that helps explain how early-life adversity permanently reshapes the brain’s stress-response systems. The study…
Why Overconfidence and Loss Aversion Evolved Together
Summary: Researchers offer an evolutionary explanation for why human overconfidence endures despite producing costly mistakes. They argue that overconfidence can act like…
Peripheral Blood Cells Restore Aging Human Microglia
Summary: Researchers have discovered that aging drives a substantial and previously unrecognized migration of bone marrow–derived immune cells from the blood into…
Depression Linked to Shrinking Memory Regions in the Brain
Summary: Researchers identified a specific structural change in the hippocampus linked with depression in older adults. High-resolution MRI scans from 2,009 cognitively…
Marmoset Genome Reveals New Alzheimer’s Insights
Summary: The common marmoset, a New World primate closely related to humans, naturally shows age-related cognitive decline, making it a valuable model…
