Cognitive energy: the neurochemically and structurally

Cognitive energy: the neurochemically and structurally supported capacity for sustained attention, working memory, executive function, and complex cognitive processing that is directly influenced by blood glucose stability, neurotransmitter balance, and the metabolic state of the brain, as opposed to a fixed reservoir that is depleted by use

Why This Is a Definition

This definition precisely establishes what 'cognitive energy' means in the curriculum context, distinguishing it from the intuitive model of fixed energy reservoirs. It specifies the genus (capacity for cognitive processing) and differentia (directly influenced by blood glucose, neurotransmitters, and brain metabolic state) while clarifying that it's not a finite resource but a metabolically supported system.
