When we’re excited by a sensory stimulus our body secretes a chemical into the central and peripheral nervous system similar to norepinephrine (NE) and dopamine (DA) called phenylethylamine, or PEA for short. Butterflies in the stomach, tingling hands, feet and inner thighs (at least, we women can attest to the tingling thigh sensation)-it’s all PEA release that causes it.
