amphetamine it will be asserted that the classical theory does not account for the negative symptoms of schizophrenia. Further‚ using the study of a second generation antipsychotic or atypical antipsychotic‚ aripiprazole‚ it would elucidate that other neurotransmitter systems may be involved in the pathophysiology of schizophrenia. The early dopamine hypothesis had focused on excessive dopamine neurotransmission as the main aetiology of schizophrenia. This was supported when positive symptoms of the illness

There are at least 75 neurotransmitters that have been discovered through research. Further discussed will be glutamate‚ GABA‚ serotonin‚ acetylcholine‚ endorphins‚ and dopamine. Glutamate is the most prominent neurotransmitter and has the ability to excite almost every neuron within the nervous system. Glutamate is also known as glutamic acid and plays an important part

When alcohol is consumed and reaches the brain‚ it can alter neuron membranes‚ ion channels‚ enzymes‚ and receptors. The receptors that alcohol binds to are the ones for acetylcholine‚ serotonin‚ gamma aminobutyric acid‚ and glutamate. The two neurotransmitters that distress the behavior effects from alcohol are the

They have changing sizes‚ shape and functions. ii. Glia- which are most of the time smaller than neurons have many

The two effect of the environment on physiological processes that will be discussed are the enrichment of certain environments on brain plasticity and the observation of experiences actions on the activation of mirror neurons. The first effect of environment on physiological processes that will be discussed is

Elias’s Response Alice Parker‚ the author of article 1‚ "Teens Are Just as Sedentary as 60 Year Olds‚" professes that obesity in America has grown and still is growing as it shows no signs of slowing down. When one is born they obviously eat‚ but as they get older they eat more and more as they continue to grow. But when one exercises than that is where obesity comes to a stop‚ if you exercise you have a high chance of not being overweight. As article 1 states‚ "The latest study published

The most important of these neurotransmitters is serotonin‚ it is a neurotransmitter responsible for maintaining mood balance‚ appetite‚ sleep patterns‚ memory‚ temperature regulation‚ learning‚ social behavior‚ and sexual desire. Serotonin can also affect the muscles‚ endocrine system‚ and cardiovascular system and other bodily functions. Anxiety and depression are strongly correlated with neurotransmitter activity which
