'''Neurotransmitters''' are [[chemical]]s in the [[nervous system]] that communicate information between [[neuron]]s.  Neurotransmitters are released from the [[presynaptic terminal]] of one neuron and cross the [[synaptic cleft]] (the space between neurons) before binding to a [[receptor]] on another neuron.  Austrian scientist [[Otto Loewi]] discovered the first neurotransmitter, [[acetylcholine]], in 1921 while experimenting on [[frog]]s.
