Substantia Gelatinosa: The Brain’s Hidden Pain Gatekeeper
The Substantia Gelatinosa (SG): Modulator of Pain and Sensory Input Core Definition and Anatomical Location The Substantia Gelatinosa (SG), often referred to by its anatomical designation, Lamina II of the spinal cord’s gray matter, represents a crucial and unique component of the central nervous system. It is specifically located within the superficial region of the […]
NEUROTENSIN (NT)
Introduction to Neurotensin (NT) Neurotensin (NT) is a specialized peptide hormone and neurotransmitter that plays a fundamental role in a diverse array of physiological processes within the human body. As a primary chemical messenger, it is instrumental in the regulation of homeostasis, the modulation of pain perception, and the complex orchestration of growth and development. […]
SPINAL GATE
Introduction to the Spinal Gate Mechanism The concept of the Spinal Gate, frequently referenced as the gating mechanism, is foundational to understanding the neurophysiology of pain perception and modulation within the central nervous system. This mechanism is an active, regulatory filter situated strategically within the dorsal horn of the spinal cord, primarily involving the intricate […]
