Dale's Law (Dale's Principle)
Dale’s Law or Dale’s principle asserts that a neuron performs identical chemical actions at all of its synaptic networks. This was named after Henry Hallett Dale, an English neuroscientist and pharmacologist. However, many experts view Dale’s statement as vague and there are two known interpretations. Some think that the principle claims that a neuron only releases one neurotransmitter at all synaptic terminals while other's interpretation state that neurons release identical sets of transmitters at all synaptic terminals.
