Dopamine

The neurotransmitter dopamine has been scrutinized in order to understand its role in mediating stress response in the brain. In particular, empirical studies have assessed dopamine release patterns during periods of acute or chronic stress in brain regions such as the prefrontal cortex, striatum and hippocampus. The evidence found region specific responses of dopaminergic systems in these areas. Previous studies have also shown that the sensitivity and magnitude of dopamine release in these…

One of the ways music affects mood is by stimulating the way of certain brain chemicals like listening to music increases the neurotransmitter dopamine. What is dopamine? “Dopamine is the brain’s “motivation molecule” and an integral part of the pleasure-reward system.” Like when you listen to your favorite song it triggers a small dopamine boost which gets you feeling excited. Music can be used in various of ways it can put your moods from sad to feeling relaxed. It does all sorts of things to…

marijuana blunts the brain's ability to respond to dopamine, the neurotransmitter that's responsible for our feelings of pleasure, motivation, and reward. Many abused substances stimulate brain dopamine signaling - the mechanism underlying the rewarding effects of drugs, food, and sex. Both groups produced just as much extra dopamine after taking the drug, but the marijuana abusers had significantly blunted behavioral, cardiovascular, and brain dopamine responses to the stimulant. Unlike cocaine…

notification, you get a little dopamine release. Dopamine, although thought to control the “pleasure” systems of the brain, actually causes you to want, seek out, and each. Dopamine’s increasing in arousal and motivation to search for information is vital from an evolutionary standpoint to move through the world and survive. However, once Dopamine has started your seeking, you get rewarded for the seeking, which makes you seek more and you begin to run in an endless loop. Dopamine loops are…

Mr. Borg’s dopamine drip was titrated to 9 mcg/kg/min in 500 ml D5W to maintain a systolic pressure of 90 mm Hg. Dopamine is an organic chemical that occurs naturally in the body to keep the heart pumping. Dopamine (Intropin) can be used to treat low heart rate during shock (“Dopamine Injection: Uses, Dosage & Side Effects - Drugs.com,” 2015). Furosemide (Lasix). The physician prescribed furosemide…

to take the drug over and over again. With repeat use the brain starts to adjust to the release of dopamine. As this release continues, the amount of dopamine receptors are reduced,some of the neurons die, or the neurons just make less dopamine. This is when the drug user becomes depressed and feels flat. Therefore, they need drugs to reach normal dopamine and need even more drugs to reach a dopamine flood or "high." This has to do with the "Pleasure" Effect of drugs. The "Pleasure" Effect is…

Emotion has a big impact on how well we are able to perform and learn. As students we don’t give enough emphasizes on the effect that emotion has on how well we can learn. Students often find themselves frustrated on the fact that they are unable to learn a certain subject, but they never stop to think why that is. In most situations it had to do with the attitude or maybe a negative emotion they might be feeling. According to David A. Sousa’s “Mind, Brain, Education,” we develop nonconsicious…

Side effects and symptoms of dopamine agonist medications can be presently seen in a person within six weeks of taking the medication (Drugs 2). The drug Levodopa is thought to be the most effective drug for controlling the symptoms of Parkinson’s disease, but Levodopa has not been shown to slow disease progression. Taking this medication is supposed to delay the symptoms of PD, but it could even make it worse. Additionally, the drug has significant abnormal side effects for some patients such…

Alcohol has a significant effect on the brain, acting on neurons and various neurochemicals. It can modify cell membranes, along with their ion channels, enzymes and receptors. Alcohols’ effect on the central nervous system (CNS) is largely due to its action on different neurotransmitters. A major inhibitory neurotransmitter in the central nervous system is gamma-aminobutyric acid (GABA). Alcohol amplifies the effect of GABA by binding to and stimulating GABA receptors, causing the opening of…

There are a wide range of explanations for schizophrenia (SZ), ranging from genetics to psychodynamic approaches. These theories can be grouped into two categories; biological and psychological. These two explanations have many differences such as their fundamental basis, treatments and methodology, but also have several similarities. This essay will outline, then compare and contrast various theories within the biological and psychological explanations. One aspect of the psychological…
