The paper "Auditory Hallucination in Schizophrenic Illness" describes that auditory hallucinations could be said to be a false perception of sound or experiencing internal voices and noises that do not originate from the external world and are seen to be separate from the normal brain processes. …
Paranoid thinking or psychotic symptoms which are symptoms of schizophrenia could also be experienced with high levels of dopamine in the brain. When the brain recognizes that there is excessive dopamine, symptoms which are schizophrenic appear. Schizophrenic patients also have more dopamine receptors than people without it (Barkus et al., 2007).
Glutamate is also associated with schizophrenia. It has a major role in the forming and encoding of memory. It is also thought to have a function in learning. When glutamate receptors are blocked for instance when one takes PCP, there is reported paranoia that is also a symptom of schizophrenia. Schizophrenic patients have been found to possess lower levels of glutamate compared to normal people. The two neurotransmitters interaction is said to be at the core of schizophrenia since the production of many dopamine receptors affects the glutamate receptors by blocking them and thus reducing their action (Spencer et al., 2009).
The dopamine hypothesis is generally the best explanation for the cause of schizophrenia at the neurotransmitter level. It is the most etiologic theory in psychotherapy. Its proposal that certain pathways of dopamine are overactive in schizophrenia could be true because when one takes drugs that increase dopamine, they induce positive symptoms but when the drugs that block its receptors are taken they reduce the positive symptoms. In other words, the experiences and behaviors associated with schizophrenia could be fully made clear by the transformations of dopamine function in the brain (Ven, 2006).

Since mental illnesses don’t lend themselves to physiologic proofs such as blood tests or scans, the psychiatrist/psychologist has to resort to evaluation methods such as questionnaires, personal interviews and other indirect methods of arriving at an inference.
al., 1996). The reason for this struggle has been unclear for some time, and of particular interest has been the disagreement over the location of the impairment. There are those who believe the impairment relates to "bottom-up" or basic visual processing, while others believe the impairment relates to "top-down" processing, which relates more to "acoustic properties and contextual cues" (Silverstein, Matteson, and Knight, 1996).
Previous studies have found that the use of certain substances such as butorphanol leads patients of schizophrenia to later episodes of violent behaviors. To determine if violence is related to substance abuse in patients of schizophrenia we designed a 2x2 Factorial design and compared different levels of aggression in 100 convicted patients of schizophrenia and 100 convicted without schizophrenia but with or without substance abuse.
(Ronald, 2001, p8.4) An example is the crying of a 2-year old child, which is considered quite acceptable. However, the same phenomena repeated by a man would seem quite strange.

The change in fundamental frequency over the time assists in defining musical strains and speech prosody while contrasts of simultaneous fundamental frequency are critical for musical harmony, and for segregating competing sound
A higher frequency of vibration means there is a high pitch while a lower frequency of vibration means there is a lower pitch. There is a range of sound that is heard most accurately by the human ear. Such sounds are from sources that vibrate at frequencies
The view therefore affects the manner in which we anylize and draw conclusions. The rates of mortality, mordibility and life expectancy cotinue to differ in most developed countries. This is highly influenced by social classes as well as the different income groups.
