Groundbreaking neuroscience research provides new insights into brain plasticity and neurogenesis. A study reveals that human thalamocortical connections develop following a hierarchical cortical plasticity, advancing understanding of brain development. Another landmark investigation using novel techniques definitively confirms ongoing neurogenesis in adult human hippocampi, identifying precursor cells and immature neurons up to age 78. Additionally, advanced MRI detects microstructural brain changes relevant to Parkinson's disease, potentially improving early diagnostics and treatment planning.
