Metabolic activity refers to the chemical processes occurring within living cells that involve energy production and consumption. In relation to the brain, it refers to how much energy different parts of the brain are using during specific tasks or at rest.
The process by which glucose (sugar) is broken down within cells to produce energy for cellular activities, including those happening in the brain.
Brain Energy Reserve: The amount of stored energy available for use by neurons in times when there is increased demand or decreased supply.
Cerebral Blood Flow: The rate at which blood is delivered to different regions of the brain, which plays a crucial role in supplying nutrients and oxygen necessary for metabolic activity.
