Why in news
IISc researchers identified a neural circuit in the lateral hypothalamic area (LHA) that suppresses itch behavior during acute stress, potentially offering a pathway to treat stress-induced chronic itch.
Background
Researchers at the Indian Institute of Science (IISc) mapped a neural circuit linking stress and itch. The study, published in the journal Cell Reports, identified specific neurons in the lateral hypothalamic area (LHA) that become active during acute stress to suppress itch.
