Mitochondria Power-Supply Failure May Cause Age-Related Cognitive Impairment

Image: Electron microscopic image of neurons in the brain showing the presynaptic boutons (yellow), mitochondria (purple), and synapses (blue). Credit: Salk Institute Salk scientists find mitochondria at dysfunctional synapses fail to meet energetic demand, supplying either too much or too little power and potentially causing age-related cognitive impairment Brains are like puzzles, requiring many nested …
