ReasonSkin ItchingAnd Its Pleasurable Feeling
Recent studies indicate that itch sensations are more related to nerve receptors than we realize. Itching is a sensation we all know, often relieved by scratching or gently rubbing the skin. Some bothersome itches can be treated with topical creams, while more severe cases may require oral medications.
Recent studies reveal that some itches are more reliant on the nervous system than we think. Itches usually result from surface skin lesions, and the central nervous system involved in itching responds to various nerve factors in the body.
The Role of the Peripheral and Spinal Nervous System in Itching Sensation
Itch receptors consist of histaminergic and non-histaminergic types activated by the skin, ultimately resulting in the release of neurotransmitters (synapses).
Recent discoveries show that neurotransmitters (synapses) also respond to the spinal nervous system. Itch modulators link to nerve receptors and transmit messages to the peripheral and central nervous systems.
The Brain’s Understanding of Itching
When the nervous system understands itching, the brain triggers the action of scratching, leading to relief. Recent studies show that the anterior cortex receptors in the brain (cingulate and insula), the prefrontal cortex, and even the cerebellum are involved in this process.
As covered in the health sectionSelMagzThis research not only explores anatomy but also investigates the relationship between the brain’s anterior cortex and its basal nuclei.
The Practical Link Between Itching and the Brain
There is a recognized link between the nervous system and the skin, which relates to growth and development. However, the specifics of this connection are not yet fully understood. Although identifying structures and sensory metabolism in the peripheral and spinal nervous system is intriguing, understanding its practical applications can significantly help patients.
This information can help discover better treatment methods for itching, manage chronic itch conditions, and relieve overall severe skin itching that impacts patients’ lives.
In managing atopic dermatitis, a common skin condition, controlling itching is done through central mechanisms. The primary focus of treating persistent itching is on side effects affecting all patients. Identifying nerve areas related to itching can greatly improve targeted treatment effectiveness.
