Human Brains Keep Growing New Neurons to Age 78, Karolinska Study Finds Groundbreaking Study from Karolinska Institutet A study from Sweden's Karolinska Institutet, published in Science , reveals that neuron formation in the hippocamus persists into late adulthood-offering critical insight into the enduring adaptability of the human brain. Historical Insight into Neurogenesis Research The Role of the Hippocampus in Brain Function the hippocampus, a region of the brain central to learning, memory and emotional regulation, has long intrigued scientists. The 2013 Landmark Study In 2013, Jonas Fris é n's group at Karolinska Institutet published a landmark study demonstrating that new neurons can form in the adult human hippocampus. They achieved this by measuring carbon-14 levels in DNA extracted from brain tissue , allowing them to estimate the age of the cells. Determining the Cells of Origin Nevertheless, the degree and importance of adult neurogenesis remain subjects of scien...

Brain Organoid Platform Aims to Decode Mild Blast Traumatic Brain Injury in Military personnel Traumatic Brain Injury: A Persistent Challenge for Military personnel Traumatic brain injuries have remained a persistent issue among military personnel, with the Department of Defence reporting close to 516.000 cases globally between 2000 and 2024. Johns Hopkins Launches POSITRONIC to Study mbTBI A research team from Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, together with the Johns Hopkins Bloomberg School of Public Health, is developing a next-generation brain-organoid platform to tackle this challenge. Their study — Platform to Optimally Study Injury and TRauma On Neural Integrity and Circuitry (POSITRONIC), published in Frontiers in Bioengineering and Biotechnology — outlines the core principles of platforms designed for investigating low-level blast exposure. Understanding Low-Level Blast Exposure "The cumulative impact of low-level blast exposure remain...
