This describes the physiological and psychological processes by which an individual maintains emotional equilibrium, heavily influenced by the neuroendocrine system. It encompasses the body’s capacity to modulate mood, stress response, and overall affective tone through hormonal feedback loops. Optimal regulation is essential for sustained wellness and resilience against psychological stressors.
Origin
The concept originates from the integration of affective neuroscience and endocrinology, recognizing that emotional experience is intrinsically linked to circulating hormones like cortisol and sex steroids. Affective derives from the Latin affectus, meaning ‘a feeling, disposition, or state of mind.’ Regulation implies the active balancing mechanisms governing these internal states.
Mechanism
Key mechanisms involve the HPA axis response, where hypothalamic releasing factors trigger pituitary and adrenal cascades that influence limbic system activity. Fluctuations in thyroid hormones or gonadal steroids can directly impact neurotransmitter systems that govern emotional stability. Therefore, maintaining appropriate receptor sensitivity is crucial for effective affective state regulation.
