I want to know the answer to the following question:
Chemicals called neurotransmitters are released at what part of the brain?
All the background I'm provided with is that "With few exceptions, each neuron in the brain releases the same chemical neurotransmitter, or combination of neurotransmitters, at all the synaptic connections it makes with other neurons; this rule is known as Dale's principle.". Is that enough to answer the question?
