Describe two properties of the nervous system that disprove Dale's principle.
What will be an ideal response?
Many neurons have been shown to release multiple different neurotransmitters, such as GABA, glutamate, and dopamine. Multiple different neurotransmitters can be released at different times through corelease (in which the neurotransmitters are packaged in the same vesicles, but molecules of different size are released at different times) or cotransmission (in which transmitters are packed in separate vesicles and vesicles differ in their sensitivities to calcium). Different neurotransmitters can also be released from different axon terminals of the same neuron.
