Study reveals how brain gathers threat cues, turns them into fear
Washington [US], August 16 (ANI): Scientists at the Salk Institute have discovered a biochemical route that combines hazardous sights, sounds, and odours into a single message: Be afraid. CGRP is a protein that allows neurons in two different parts of the brain to combine hazardous sensory cues into a cohesive signal, label it as negative, and send it to the amygdala, which converts the information into fear.
