As Nicole walks to her dorm room after a study group in the library she sees a backpack being stolen. The neurotransmitter activated during this emergency situation is a. norepinephrine.
High levels of norepinephrine can also lead to headaches, high blood sugar, and sleep disturbances. Too much norepinephrine also causes anxiety, high blood pressure and heart rate, and organ stress. Drug withdrawal, chronic renal disease, and mental illnesses like PTSD can also result in high norepinephrine levels. Neurons discharge neurotransmitter, which are chemical messengers, into the synapse through synaptic vesicles. Some neurotransmitter work by increasing the neuron's negative electrical charge, which makes it less likely to activate. This is a deterrent effect. Serotonin is an example of this.
