اكتشف العلماء مفتاحًا مخفيًا في الدماغ يخبرك بالتوقف عن الأكل

Your brain’s “stop eating” signal may come from an unexpected source. Researchers found that astrocytes—once thought to just support neurons—actually play a key role in controlling appetite. After a meal, glucose triggers tanycytes, which send signals to astrocytes that then activate fullness neurons. This newly discovered pathway could lead to innovative treatments for obesity and eating disorders.
