Neuropeptides, Not Neurotransmitters, Drive Brain’s Fear Response

Researchers have discovered that neuropeptides, not neurotransmitters, are the primary messengers in the brain's fear circuit. This finding could lead to better painkillers and treatments for fear-related conditions. Using innovative tools, scientists observed neuropeptide release during fear responses in live mice. The study highlights the potential of targeting multiple neuropeptides for more effective therapies.
