Within the brain, neurons produce neuropeptides to regulate emotion, pain, metabolism, and the immune response. Rather than acting only locally, neuropeptides can signal through synapses, diffuse through extracellular space, or act as circulating hormone-like messengers, producing effects that often last from seconds to minutes
