Sridharan, PhD, lead author of the study. “The normal homeostatic balance of mitochondrial fission and fusion is how mitochondria consistently produce enough energy for the cell while also sequestering and disposing damaged parts. Given the very high energy demands of the brain, this is particularly important for brain health across our lifespan.” Credit UH / CWRU Usage Restrictions N/A License Original content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
