The Nobel Prize in Physiology or Medicine was awarded to Dale in 1936. It recognized his groundbreaking research on the role of chemical transmitters in nerve impulse transmission, particularly his work on acetylcholine, a crucial neurotransmitter in the parasympathetic nervous system. Dale's discoveries have had a profound impact on our understanding of the nervous system and have paved the way for the development of various medications that target neurotransmission-related disorders.
