Acute Cognitive Modulation

Meaning

The rapid, transient alteration of mental processes such as attention, memory, and executive function in response to an immediate physiological or external stimulus. This immediate change is often linked to swift shifts in neurochemical balance or energy substrate availability within the central nervous system. Hormonal fluctuations, particularly of cortisol or catecholamines, can trigger this neurobiological response, directly impacting the speed and efficiency of information processing. Understanding this acute responsiveness is key to managing daily cognitive performance and stress adaptation.
