Soma statt Signale von außen: Wie Neuronen ihren Axon-Pfad auswählen – it boltwise

by

Researchers have uncovered a fundamental mechanism in developmental neurobiology that explains how neurons determine the path of their axons—the long, slender projections that carry electrical impulses to other cells. Contrary to long-standing theories that relied exclusively on external environmental guidance cues, recent findings indicate that the neuron’s cell body, or soma, plays a decisive role … Read more

Study Links Plasma Vitamin C Levels to Gray Matter and Brain Network Connectivity

by

Recent neuroimaging research suggests a measurable link between plasma Vitamin C levels and the structural integrity of the human brain, specifically concerning gray matter volume and the connectivity of the Default Mode Network (DMN). A study published in Frontiers in Nutritional Neuroscience indicates that higher concentrations of circulating ascorbate may correlate with enhanced neurological resilience, … Read more

Decoding Brain Aging: How Genomic Tools Are Rewriting Our Understanding of Cognitive Decline By Dr. Helena Fischer, Editor, Health | Berlin, Germany | May 13, 2026 Our brains don’t age like the rest of our bodies. While our skin wrinkles and our joints stiffen with predictable patterns, cognitive decline is far more mysterious—a silent, creeping … Read more

Loneliness Affects Memory, but Doesn’t Accelerate Cognitive Decline

by

For years, a prevailing narrative in geriatric health has suggested that the profound isolation of old age acts as a catalyst for the brain’s decline. However, new evidence is challenging the idea that loneliness directly accelerates the biological clock of cognitive decay. Recent research indicates that although loneliness significantly influences memory performance, it may not … Read more
