Brain metabolism refers to the processes by which the brain uses and produces energy to support its functions. This includes the conversion of glucose and oxygen into adenosine triphosphate (ATP), the brain's primary energy source. Brain metabolism is essential for the proper functioning of neurons, synapses, and neurotransmitter systems, as well as for the maintenance of brain homeostasis. Research in this area investigates how disruptions in brain metabolism can contribute to various neurological disorders, such as Alzheimer's disease, epilepsy, and stroke, and how targeting these metabolic pathways could lead to new treatments for these conditions. Additionally, understanding brain metabolism is crucial for developing strategies to enhance cognitive function and protect against cognitive decline.
