Summary: Researchers report that an experimental systemic gene therapy can protect the central nervous system from the cognitive decline and structural damage driven by TDP-43–related proteinopathy. The treatment uses a neuron-targeted approach that delivers the SynCav1 gene throughout the brain and spinal cord via a modified, nonpathogenic viral vector to increase levels of caveolin-1, a … Read more

Summary: A multidisciplinary neurodevelopmental review shows that laughter is a complex biological force that actively shapes early brain development, builds emotional resilience, and strengthens parent–child neural synchrony. Drawing on evidence from biology, psychology, and sociology, this research demonstrates that joy and humor act as an immediate buffer against stress. By triggering neuroplasticity, lowering cortisol, and … Read more

Summary: A major synthesis of psychological and neuroscientific research challenges a long-standing assumption: people and animals are not fundamentally averse to effort. Instead, the evidence suggests individuals avoid wasted effort — actions that produce no progress or whose payoff does not justify the cost. By reviewing developmental studies and behavioral experiments, the authors argue that … Read more

Summary: A new preclinical study from Northwestern University identifies a structural explanation for why women are disproportionately affected by Alzheimer’s disease (AD). Rather than focusing solely on neurons and glial cells, researchers examined the extracellular matrix (ECM) — the non-cellular “mortar” that fills spaces between brain cells — and found that aging combined with loss … Read more

Summary: Researchers have traced a precise brain circuit that produces the nocebo effect — the biological process by which negative expectations increase physical pain. The study shows that anticipation, fear, or observing another’s suffering triggers release of the neurochemical cholecystokinin (CCK), which travels along a defined pathway to amplify pain sensitivity. This work provides direct … Read more

Summary: A new study overturns the long-standing assumption that sodium concentration is uniformly low across astrocytes—the star-shaped glial cells of the brain. Using a novel real-time imaging approach, researchers visualized sodium levels inside astrocytes and their ultra-fine processes for the first time, revealing dynamic, localized sodium micro-domains that adapt to nearby neuronal activity. Rather than … Read more

Summary: A comparative neurodevelopmental study has identified a cellular timing mechanism that determines species-specific proportions of the mammalian cerebral cortex. The research shows that differences in cortical layer composition arise from altered “aging rates” of neural progenitor cells during early embryonic development, with prolonged production of deep-layer neurons driven by extended Wnt signaling activity. By … Read more

Summary: Researchers have redefined a key biological mechanism related to obsessive-compulsive disorder (OCD) by showing that serotonin directly reduces what they call “belief stickiness” — the tendency to persist with an outdated belief about the state of the world despite clear, contradictory evidence. In a randomized, double-blind clinical trial, participants completed a changing-environment task while … Read more

Summary: A new study overturns longstanding assumptions about how we learn and retain speech movements, showing that sensory brain areas — those that process sound and touch — are essential for maintaining newly learned speech patterns, while primary motor regions are not. Researchers found that temporarily disrupting the auditory or somatosensory cortex severely reduced participants’ … Read more

Summary: A single dose of psilocybin, the active compound in psychedelic “magic” mushrooms, produced long-lasting reductions in neuropathic (nerve) pain in mice and markedly improved the effectiveness of the commonly prescribed pain medication gabapentin. The work, led by researchers at the University of Reading and published in Communications Biology, suggests psilocybin reshapes pain-processing networks in … Read more
