Metabolism in the brain fluctuates with circadian rhythm
(Medical Xpress)—The rhythm of life is driven by the cycles of day and night, and most organisms carry in their cells a common, (roughly) 24-hour beat. In animals, this rhythm emerges from a tiny brain ...

Study reveals how anesthetic isoflurane induces Alzheimer's-like changes in mammalian brains
The association of the inhaled anesthetic isoflurane with Alzheimer's-disease-like changes in mammalian brains may by caused by the drug's effects on mitochondria, the structures in which most cellular energy is produced. ...
