Attentional Networks

Meaning

These are the distinct, distributed neural systems responsible for selecting, focusing, and sustaining cognitive resources on specific stimuli while filtering out distractions. Within the context of hormonal health, these networks are profoundly influenced by neuroendocrine modulators, such as cortisol, thyroid hormones, and sex steroids, which impact their efficiency and resilience. Fluctuations in these endocrine signals can directly alter an individual’s capacity for concentration, cognitive flexibility, and executive function. Maintaining homeostatic hormonal balance is therefore critical for optimal performance of the brain’s complex regulatory architecture.
