neurotransmitters called dopamine. “Dopamine is the brain’s primary motivation neurotransmitter (Polito). “ For example‚ when you are hungry or thirsty and you finally find time to eat or quench your thirst‚ that overwhelming‚ satisfactory sensation is caused by the flow of dopamine released from the brain. Nicotine is an external chemical that passes through the blood/brain barrier that stimulates dopamine. Once there is that chemical dependency on nicotine in order for your brain to release dopamine‚ it becomes

the brains primary motivation neurotransmitter‚ dopamine. The dopamine pathways that make up the brain serve as a built-in- teacher or memory (Polito‚ 2012). This certain function triggers a feeling of desire or sensation when wanting the required action to takes place (Polito‚ 2012). In a sense the dopamine pathways are testing the body to see if it will give into the urges. Once an individual loses control and gives into the urge the dopamine is stimulated‚ and the desire is satisfied. According

Elevated levels of vasopressin V1a receptor (V1aR) was discovered to cause the differences in behavioral differences between the prairie vole and the meadow vole. Dopamine receptors were determined to not differ in the two species‚ but it is necessary for V1aR modified meadow voles to display partner

Dopamine is a biogenic amines that plays an important role in the body and is released throughout the brain. Dopamine and other types of biogenic amines functions includes regulating our biological clock and emotional behavior (Marieb and Katja Hoehn‚ 2013‚ p. 414).

factors in this diagnosis. (Pinel‚ 2011) Altered courses of neurodevelopment are the biggest theory by far. Another theory proposed is the release of dopamine through receptors. One theory posed that an elevated amount of dopamine caused Schizophrenia‚ whereas another theory posed that not enough dopamine but rather the elevated activity at dopamine receptors being a causal route of the diagnosis. Further research has pinpointed this to be a more accurate theory with activity levels and the body’s

Muhammad Ali is considered by many to be one of the greatest boxers of all time. He fought inside the ring‚ becoming the only three-time lineal heavyweight champion‚ and outside of the ring for racial and religious equality. One of the greatest fights in his life‚ however‚ was his battle with Parkinson’s disease. Ali was only 42 years old when he was diagnosed with the disease in 1984. Though the cause of Parkinson’s is not often known or is attributed to genetic factors‚ doctors have attributed

This is called a positive symptom of schizophrenia. In addition‚ the overproduction of dopamine occurs. This causes a decrease in glutamate and neural activity. The temporal lobe controls hearing and the identification of objects and faces. When a person has schizophrenia‚ the hearing and identification becomes chaotic. This can cause the

One biological explanation for unipolar depression is the monoamine hypothesis. The monoamines are a group of neurotransmitters which include serotonin‚ noradrenaline and dopamine. You will recognise the latter‚ dopamine‚ from the biological offering of an explanation for schizophrenia. The monoamines are believed to regulate mood. One of the functions of serotonin is to regulate the other neurotransmitters. Without the regulation provided by serotonin‚ erratic brain functioning and thinking patterns
