Dopamine is chemically stable and it shows no selectivity between the dopamine receptors in the brain and the periphery. This is also a reason for it being an unsatisfactory treatment. Page reference: 237, 242-243. a. Dopamine is not sufficiently polar to cross the blood brain barrier. b. Dopamine …

In response to the action potential signal they are diffused across the synapse. ... Acetylcholine was the first neurotransmitter to be discovered . ... and drugs that block dopamine are used to help schizophrenics. On the other hand, too little dopamine in the . motor.
Dopamine Functions
Using what you have learned about the effects of the neurotransmitters glutamate and GABA, determine how the different signals that affect Neuron #1 can change the release of the neurotransmitter dopamine from Neuron #2. Use the chart to help you work through the cases.

B. Cocaine is a dopamine agonist. Dopamine is also a precursor (chemically) to epinephrine and norepinephrine. How do these facts explain some of the effects of cocaine? C. Serotonin reuptake inhibitors serve as antidepressants. Under the action of a SRI, how is the serotoninergic synapse different? (That is, what happens to serotonin levels?)

The diagram above [right] shows the major steps in the action of the neurotransmitter dopamine. First, dopamine is synthesized from the amino acid tyrosine. The dopamine is then stored in the synaptic vesicles of the presynaptic neuron until it receives action potentials that cause it to release the dopamine into the synaptic gap by a process ...

Low Dopamine levels can drive us to use drugs (self medicate), alcohols, smoke cigarettes, gamble, and/or overeat. High dopamine has been observed in patients with poor GI function, autism, mood swings, psychosis, and children with attention disorders. Glutamate is the major excitatory neurotransmitter in the brain.

This is a diagram of a dopamine neuron (in yellow) originating in the VTA and projecting into the nucleus accumbens. These dopamine neurons are regulated by a variety of neurotransmitter systems: excitatory NMDA systems (red) inhibitory GABA neurons (green) opioid neurons and receptors (blue) S18 2. Effect on the GABA System
