Cognitive Energy Output

Meaning

Cognitive Energy Output refers to the quantifiable expenditure of metabolic energy, primarily glucose and oxygen, by the brain to support complex executive functions, processing speed, and sustained mental effort. This metric reflects the efficiency and capacity of neuronal metabolism to power high-level cognitive tasks. Optimal output is characterized by stable attention, clear decision-making, and resistance to mental fatigue, all of which are deeply sensitive to hormonal milieu. Diminished output is a clinical sign of neuro-metabolic compromise or endocrine dysregulation.
