Mouse study identifies C1 neurons as a driver of prolonged fear and anxiety

Anxiety disorders impact much than 300 cardinal radical globally. Several encephalon regions person been linked to anxiety, but however these regions link has been poorly understood. By exploring these connections, scientists astatine St. Jude Children's Research Hospital revealed that epinephrine-producing C1 neurons successful mice modulate fearfulness and anxiety.
