the brain called the basal ganglia. This part of the brain has a role in controlling muscle movements. What happens is that nerve cells in the basal ganglia begin to die. These nerve cells contain a brain chemical called dopamine to help control muscle movement. Without dopamine‚ the nerve cells in the basal ganglia cannot properly send messages. This leads to the loss of muscle function which then is identified as Parkinson’s disease.

Covalent Compound: Cocaine Cocaine‚ also known as coke‚ is a covalent compound‚ which are molecules that consist of groups of atoms held together by covalent or coordinate bonds. In the United States cocaine is an illegal drug because of the harm it does to a human’s body. It has been used for many years for many different reasons by many different people.

The goal of conventional antipsychotic drug therapy is to reduce the amount of dopamine‚ or the amount of dopamine receptor sites. They are dopamine antagonists in that they bind dopamine receptors and blocking their action. Conventional drugs can reduce acute‚ positive symptoms ed. hallucinations. They produce the maximum

Other nitrogen containing compounds Catecholamine: Dopamine‚ norepinephrine (noradrenaline) and epinephrine (adrenaline) are biologically active amines and are collectively called as Catecholamine. * Dopamine and norepinephrine functions as neurotransmitters. Outside the nervous system‚ norepinephrine and its methylated derivative‚ epinephrine regulates carbohydrate and lipid metabolism. They are released from storage vehicles in the adrenal medulla in response to stress (fright‚ exercise‚ cold

Hi Jonnah‚ I know we haven’t talked since you transferred high schools‚ but I hope you are doing well! In 8th grade I remember you having a lot of trouble with your epilepsy. You wore sunglasses indoors because the light always triggered seizures and even when you did wear them‚ you had seizures at school. It was always scary to watch‚ but I can’t even imagine how scary it was for you to go through them. Back then‚ I knew nothing about epilepsy. All I knew is that it affected my friend‚ and I hated

A biological explanation of schizophrenia is the dopamine hypothesis‚ amounts of low levels of dopamine in the brain causes a loss of balance and co-ordination‚ it has been found in people with ADHD and Parkinson’s disease. Where as high levels of dopamine is linked to schizophrenia.

There are newer imaging techniques being performed such as the DaTSCAN‚ which specifically evaluates for the amount of dopamine in the substantia nigra – the abnormal brain region in Parkinson disease. The only way doctors know you have Parkinson disease for certain is if they perform brain autopsy after death. Your doctor will also likely order blood tests such as a CMP

suggests that genetic factors may create a predisposition to the initiation of an addiction. An individual who inherits a genetic abnormality relating to the regulation of dopamine is more likely to develop an addiction. An individual who possesses such an abnormality will be less sensitive to the rewarding effects of dopamine‚ meaning that they need to engage in a behaviour more to feel the reward‚ therefore they are more likely to initiate an addiction. It has been found that the SLC6A3-9 gene

In the brain‚ pleasure releases a neurotransmitter called dopamine. Dopamine is released into the nucleus accumbens‚ what neuroscientists refer to as the brain’s pleasure center. Laying down memories of this rapid sense of satisfaction‚ creates a conditioned response to certain stimuli (Leshner‚ 1997). Over time‚ the
