Neurons release different types of neurotransmitters. These neurotransmitters are associated with certain behavioral effects. Which answer accurately describes the relationship between several major transmitters and behavior?

The neurotransmitters that are substances transmitted through synapses in neurons determine much of our behavior, the perception of our senses and our emotions.

For example, the neurotransmitter norepinephrine is associated with the maximum alertness of our nervous system. The serotonin is related to emotion and mood. When there are low levels it has been shown to lead to depression or anger.
