This example is known as the glutamate hypothesis which theorizes the idea that the brain receives a little amount of glutamate neurotransmission and not enough dopamine neurotransmission (Eagleman & Downer, 539). Olney and Farber (1995) found that this caused many of the symptoms of schizophrenia (Eagleman & Downer, 539). Moreover on this idea, Corlett, Honey, and Fletcher (2007) found that a good portion of schizophrenic patients have lower glutamate levels and tend to have differences in their NMDA receptor expressions (Eagleman & Downer, 539). A lot of these findings were similar to the effects of drugs like PCP (which block NMDA glutamate receptors) which tend to have side effects like hallucinations and states of fear (Eagleman & Downer, 539). A third example of a neurological cause of schizophrenia is what is known as the dopamine hypothesis. This hypothesis is the idea that irregular levels of dopamine, in the case of schizophrenia, high levels of dopamine, are linked to some of the symptoms of schizophrenia (Eagleman & Downer, 539). This idea was thought of because of the findings on the use of amphetamines causing a rise in dopamine in the brain as well as the rise of the symptoms of schizophrenia (Seeman & Lee, 1975)( Eagleman & Downer, 538). There are a few different treatments used for schizophrenia. However, one of the most prevalent treatments for schizophrenia is the antipsychotic prescription drug. One of the
