WebOrgans that have classically been thought to be dependent solely on glucose, such as the brain, can actually use ketones as an alternative energy source. This keeps the brain functioning when glucose is limited. When ketones are produced faster than they can be used, they can be broken down into CO 2 and acetone. WebOur study revealed the general principle of brain energy-activity organization and suggests that the metabolism-neural synchrony pathway could be a new potential treatment target for psychotic disorders.
