Neuroimagery is a clinical speciality that produces images of the brain by using non-invasive techniques, i.e.: without requiring surgery, incision of the skin, or any direct contact with the inside of the body. This type of imagery falls into two categories: Structural; this deals with the structure of the brain and aids the diagnosis of diseases (e.g. brain tumours) and Functional; this is used for neurological and cognitive research purposes, along with the diagnosis of metabolic diseases (e.g. Alzheimer’s and Parkinson’s). Neuroimagery enables us to directly visualize the processing of information by the centres of the brain. This processing causes the involved area of the brain to increase metabolism and as a result highlight itself on the screen in a prominent colour.
The first neuroimaging technique was known as the “Human Circulation Balance”, which was invented by Angelo Masso in the 1880’s. This method of neuroimagery was able to measure the redistribution of blood during emotional and intellectual activity using the non-invasive techniques outlined above. There have been significant changes in technology since this, including the introduction of Magnetic Resonance Imaging scans (MRI) in the 1970’s and Computed Axial Tomography scans (CT) in the 1980’s. From these methods of neuroimagery came Magneto encephalography (MEG), Position Emission Tomography (PET), Electroencephalography (EEG) and Functional Magnetic Resonance Imagery (fMRI).
The advances in technology of neuroimagery have enabled us to see what parts of the brain are stimulated when carrying out certain tasks. For example, Schon et all discovered that when reading music, a tiny spot at the back of the head (known as the right superior parietal cortex) becom...

Nowadays, it is widely known that the right and left hemisphere have different functions. The two hemispheres are equally important in a daily life basis. Nevertheless, in the 1960’s this was not common knowledge. Even though today the importance of the brain hemispheres is common knowledge, people don’t usually know to whom attribute this findings. One of the people who contributed to form a more defined picture about the brain hemispheres and their respective functions was Roger Wolcott Sperry, with the split brain research. Roger Sperry did more contributions than the split brain research, but this is his most important and revolutionary research in the psychological field. Thanks to the split brain research, Sperry proved that the two hemispheres of the brain are important, they work together and whatever side of the brain is more capable of doing the task is the hemisphere that takes the lead.
Neuropsychology is the strongest and exciting area of science and psychology to date by applying principles of scientific evaluation and intervention derived from the study typical and irregular performance of the brain and central nervous system. Neuropsychologists are devoted to understanding the relationship between human behavior and the brain and understanding the application of neuropsychology to issues that society face everyday. With medical technology at it disposal neuropsychologist are able to use brain scan devices to evaluate neurological disorders from the brain response to individual behavior. Many neuropsychologists are employed via grant work, but many have salary jobs with research facilities associated with hospitals, university, clinics, labs and large medical pharmaceutical

For example, a study was done by, Cunningham, (2007), he believed that brain implicit attitudes operates through our unconscious emotion and that because the presentation of subliminal black faces activated our amygdala rather than white faces. The amygdala is known for its negative, and fearful sensitive, now it is also known for positive information after suffering from brain injury. Cunningham, (2007), have demonstrated that the amygdala depending on the perceiver might respond differently with processing affective intensity as opposed to various valence which cause the brain injury person to respond differently. Brain lesions have been linked by researchers and also brain lesions are related to cognitive deficits. The imagery of brain lesions were study in patients. The patient underwent surgery that served their right hemisphere from their left hemisphere. According to, (Sternberg, 2009), the right hemisphere appeared to represent visuospatial knowledge, whereas, the left hemisphere geared move toward symbol based knowledge. Moreover, the right hemisphere also represent being connected to the analogous to our physical environment as well. Nonetheless, the left hemisphere associates imaginal components along with symbols and to collect entirely new information entirely after undergoing brain

Cognitive psychology is the study of the brains internal processes that guide behaviour; to study cognition, psychologists examine case studies of patients with damaged brains that can infer areas, and functions involved in particular processes. Patient studies have provided insights into the processes that take place within our minds, and have enabled psychologists to create models, which can be tested and fractionated. Cognitive neuropsychology has developed from cognitive psychology to become a discipline in its own right; it investigates the function and structures of the brain involved in cognitive processes and should not be confused with cognitive neuroscience, which is primarily concerned with neural structures and their functions.
Thesis Statement: Violence in video games does not affect levels of aggression in people as long as you follow the MSRB rating scale.
As previously stated, neuroimaging science and study began in the early 1900s. The “great granddaddy” of functional brain viewing is electroencephalography, or EEG, and was invented by a German researcher by the name of Hans Berger. This exceptional neurologist discovered that the electrical activity of the brain is detectable outside the head. Following Berger’s steps, a group of scientists came up with ...
Since the brain is extremely fragile and difficult to access without risking further damage, imaging techniques are used frequently as a noninvasive method of visualizing the brain’s structure and activity. Today's technology provides many useful tools for studying the brain. But even with our highest technology out there we do not know everything definitely. We do have fallbacks at times and these fallbacks can lead to serious problems.
A neuropsychologist is a psychologist who specializes in studying brain behavior relationships. Neuropsychologists have extensive training in the anatomy, physiology, and pathology of the nervous system. Some neuropsychologists specialize in research while other neuropsychologists specialize in evaluating and treating people who are thought to have something wrong with the way in which their nervous system is functioning.
