Evaluate the use of brain imaging technologies in investigating the relationship between biological factors and behavior in terms of the presentation of schizophrenia
Brain imaging techniques allow psychologists and doctors to analyze the human without direct surgery. Schizophrenia is a mental disorder that causes hallucinations, delusions and disorganization in the human brain. Through the many brain imaging technologies, such as position emission tomography (PET) and functional magnetic resonance imaging (fMRI), the biological factors and behavior of schizophrenia can be discussed and evaluated.
In order to outline and evaluate the use of brain imaging in schizophrenia, it is important to be well informed about the causes and symptoms of the mental disorder. Schizophrenia affects the cognition processes and emotional responses of people which can be seen when they find it difficult to identify the line between real and imagery and show distress. It is significant to know that schizophrenia should not be confused with split personality. Some common symptoms of schizophrenia are hallucination, thought and movement disorder, delusion, lack of emotions and senses, and problems with memory. There are many theories about the causes of schizophrenia but it is still not clear about the exact cause of this brain disorder. The most notable factors that explain schizophrenia are brain structure and genetics.
Scientists found that the disease tends to be more prominent in families that had schizophrenia before. Schizophrenia is presented in 1 percent of the world’s population and 10 percent in people who have relatives that had the disorder. The highest possibility can be seen in monozygotic twins. This can be developed by the twin s...

According to (Barlow, 2001), Schizophrenia is a psychological or mental disorder that makes the patient recognize real things and to have abnormal social behavior. Schizophrenia is characterized by symptoms such as confused thinking, hallucinations, false beliefs, demotivation, reduced social interaction and emotional expressions (Linkov, 2008). Diagnosis of this disorder is done through observation of patient’s behavior, and previously reported experiences (Mothersill, 2007). In this paper, therefore, my primary goal is to discuss Schizophrenia and how this condition is diagnosed and treated.

Individuals with schizophrenia are required to have MRIs or CT scans due to the theory that schizophrenia may stem from a physical abnormality in the brain. MRIs and CT scans of schizophrenic patients have seen enlarged ventricles which results in the loss of brain cells. Once brains cell exit the brain, it leaves the individual more vulnerable to hallucination, delusions and decreases their body control abilities. These scans have also seen structural abnormalities in the prefrontal temporal cortex and the temporal-limbic area of the brain. The prefrontal temporal cortex is critical in judgment, insight, motivation, and mood. The temporal-limbic area is located at the bottom of the brain and it involved in the retention of visual memories, processing sensory details, comprehending language, storing new memories, emotion, and finding meanings. It is obvious that abnormalities in these areas of the brain can and will cause schizophrenia symptoms. These abnormalities are most commonly produced by genetic pairings. (Begeley 1.)
Due to neurological studies of the brain, antipsychotic drugs have become the most widely used treatments. These studies show that there are widespread abnormalities in the structural connectivity of the brains of affected people. (2) It was noticed that in brains affected with schizophrenia, far more neurotransmitters are released between neurons, which is what causes the symptoms. At first, re...

Schizophrenia is a disease of the brain that is expressed clinically as a disease of the mind. Once it strikes, morbidity is high (60% of patients are receiving disability benefits within the first year of onset) as is mortality (the suicide rate is 10%). (www.nejm.org/content/1999/0340/008/0645.asp). Because its symptoms and signs and associated cognitive abnormalities are diverse, researchers have been unable to find localization in a single region of the brain. This essay will discuss the symptoms, treatments and causes of schizophrenia.
Schizophrenia is a serious, chronic mental disorder characterized by loss of contact with reality and disturbances of thought, mood, and perception. Schizophrenia is the most common and the most potentially sever and disabling of the psychosis, a term encompassing several severe mental disorders that result in the loss of contact with reality along with major personality derangements. Schizophrenia patients experience delusions, hallucinations and often lose thought process. Schizophrenia affects an estimated one percent of the population in every country of the world. Victims share a range of symptoms that can be devastating to themselves as well as to families and friends. They may have trouble dealing with the most minor everyday stresses and insignificant changes in their surroundings. They may avoid social contact, ignore personal hygiene and behave oddly (Kass, 194). Many people outside the mental health profession believe that schizophrenia refers to a “split personality”. The word “schizophrenia” comes from the Greek schizo, meaning split and phrenia refers to the diaphragm once thought to be the location of a person’s mind and soul. When the word “schizophrenia” was established by European psychiatrists, they meant to describe a shattering, or breakdown, of basic psychological functions. Eugene Bleuler is one of the most influential psychiatrists of his time. He is best known today for his introduction of the term “schizophrenia” to describe the disorder previously known as dementia praecox and for his studies of schizophrenics. The illness can best be described as a collection of particular symptoms that usually fall into four basic categories: formal thought disorder, perception disorder, feeling/emotional disturbance, and behavior disorders (Young, 23). People with schizophrenia describe strange of unrealistic thoughts. Their speech is sometimes hard to follow because of disordered thinking. Phrases seem disconnected, and ideas move from topic to topic with no logical pattern in what is being said. In some cases, individuals with schizophrenia say that they have no idea at all or that their heads seem “empty”. Many schizophrenic patients think they possess extraordinary powers such as x-ray vision or super strength. They may believe that their thoughts are being controlled by others or that everyone knows what they are thinking. These beliefs ar...
