Importantly for schizophrenia‚ dopamine appears to play a big role in the activity in the frontal and temporal

Dopamine is a neurotransmitter that transports signals between nerve endings in the brain. It is thought that the brains of people with schizophrenia produce too much dopamine. Antipsychotic medications‚ which are used to treat schizophrenia‚ block dopamine receptors. The medications are designed to bind to dopamine receptors in the brain‚ and their effects have helped many people cope with symptoms; while drugs that increase levels of dopamine‚ like amphetamines‚ often

research laboratory in Princeton University by Professor Bart Hoebel. He experimented with rats overeating a sugar solution. The rats would go twelve hours without food and than be given a sugar solution with their meal. The experiment was to release dopamine into the rat’s brain the same way in which it is released into a drug addict’s brain. The research concluded‚ “ that the rats developed many behaviors and changes in the brain that are similar to the effects of some drugs of abuse‚ including naloxone-precipitated

because cotinine will act as a partial agonist to increase dopamine release‚ but not to the same magnitude as nicotine (120). Overtime‚ it is expected with the use of Co-MAO and gradual decrease in dosages‚ there should be a reduction of the number nicotinic receptors to normal levels. The selective MAOB inhibitor‚ helps offset the absence of other substances in tobacco that had previously inhibited monoamine oxidase activity to catabolize dopamine‚ norepinephrine‚ and serotonin
