Hope for itching sufferers
Print Edition
ITCHING is one of the most common sensations in our daily life, but the neural mechanism underlying the irritating sensation has been largely unknown.
Local neuro-scientists have for the first time revealed how itch signals are transmitted from the spinal cord to the brain by discovering a central neural pathway.
Their paper was published online in the Science journal on August 18.
Itching is an unpleasant sensation making its sufferers wants to scratch. For ordinary people it is irritating but bearable.
“But for patients with skin or liver diseases, chronic itching could lead to uncontrollable scratching,” said Dr Sun Yangang, a leading researcher of the team.
“Their scratching could even affect their sleep and quality of life,” Sun added.
