Neuropeptide Y (1-24) (human) is a neuropeptide with potencies in inhibiting the electricity stimulated twitch response of rat vas deferens. Neuropeptide Y (1-24) (human) stimulates N-methyl-D-aspartate (NMDA)-induced neuronal activation in the rat CA3 region of the dorsal hippocampus in vivo[1][2].
