Brain Mitochondria Map Sheds Light on Cognitive Decline

Researchers have created the first 3D map of mitochondria in the human brain, revealing that older, evolutionarily ancient regions have fewer mitochondria and lower energy production, which correlates with declines in functions like balance and breathing, while newer cortical areas with higher mitochondrial density support complex tasks like language and planning. This mapping could lead to personalized interventions for cognitive aging and neurodegenerative diseases by identifying regions with energy shortfalls before symptoms appear.
