attained through numerous different activities. Dopamine is a key chemical in the human body’s process of reward sensation. This chemical release can be measured by neuroscientists through brain monitoring equipment. Though there is some debate over the degree to which dopamine is involved in the chemical process of reward‚ it is a widely known and accepted fact that during the sensation of reward‚ the human body produces excess amounts of dopamine (Berridge 4).

I take medications that impact both the GABA and Serotonin neurotransmitters and Dopamine and Norepinephrine because I find them fascinating.

Dopamine is an important neurotransmitter in the nervous system that communicates a lot of information between neurons and parts of the brain. The networks of neurons that use dopamine appear to influence activity in different areas of the brain so that abnormalities can cause abnormal activities in certain parts of the brain. Importantly for schizophrenia‚ dopamine appears to play a big role in the activity in the frontal and temporal

This link is seen to be the side effects of smoking. Tabacco has been widely popular because it delivers significant doses of nicotine to the brain‚ which affects the dopamine receptors in the brain to give tobacco smokers pleasure. Smoking cigarettes is extremely reinforcing this is the result of both the physical addiction to nicotine and the psychological complement of smoking. (Kozlowski‚ Henningfield‚ & Braigham‚

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

1) How are monism and dualism being used by the social sciences? One of the big topics in psychology is trying to understand and define the mind. It is a question that it is proposed in most psychology classes I have taken‚ and it is difficult to give an exact answer. What is the mind? How does the mind work in relation to the brain? I think that if asked‚ everyone would have their own slightly different answer to question. This is because the mind is not a concrete thing we can easily define
