Neuronal Energy

Meaning

Neuronal Energy refers to the metabolic capacity and available adenosine triphosphate (ATP) required to support the high energy demands of neuronal signaling, synaptic transmission, and maintenance of ion gradients within the central nervous system. The brain, despite its relatively small mass, consumes a disproportionately large amount of the body’s total energy, primarily in the form of glucose and, secondarily, ketones. Adequate neuronal energy is fundamental for optimal cognitive function, mood stability, and the complex regulation of the neuroendocrine axes. Deficits in this energy supply can manifest as cognitive fatigue or impaired central hormonal control.
