A chemical substance present in neuron. Transmits nerve impulse from one to another neuron. Thus also called a mediator for impulse transmission. Transmission occurs through synapse. Discovered first by Otto Loewi in 1921. Was an Austrian scientist who practically came out with this discovery. Criteria for Neurotransmitters Various substances are categorized as neurotransmitters. Following criteria … Read more
