...numerous ways in studying methods of the brain. It ranges from electrical and chemical stimulation, recordings of the electrical activity from the brain, scanning and imaging techniques, and so on. The effects of electrical and chemical stimulation take place within different places in the brain that selectively affect specific psychological processes as well as psychologically active medications; anesthetics and recreational drugs). These selectively affect different mental processes because they act on the brain in different brain systems. Small amounts of psychologically active chemicals can be injected into small parts of the brain. These experimental ways have helped identify the location and function of brain systems that carry out the effects of these chemicals. Through electrical stimulation, we can only stimulate the desired part of the brain. The advances in technology have made it possible to study the internal work of the brain without having to cut into an individual’s skull. The brain scanning is the mechanical and electrical measurements of the specific activates of the brain. One example I am familiar with of a scanning technique is the MRI, or magnetic resonance imaging. It uses a magnetic field in which the individual’s head is put in place. The radio waves aimed in the brain cause certain atoms within the brain to emit signals which the computer picks up. These studying techniques can distinguish between closely related brain structures. There are a variety of...

...CheckPoint: Brain Studies PSY/240 Teacher: Lorry J Bradley Kimberly Roberts 10/12/2012 These are the five research methods that I chose out of our text: 1. Contrast X-Rays : Contrast x-rays involve injecting a substance into an area of the body that absorbs x-rays around the surrounding tissue. The injected substance shows the contrast between the compartment and surrounding tissue during an x-ray photograph. Cerebral Angiography is the process that uses radio opaque dye into a cerebral artery that shows the cerebral circulatory system. Contrast X-rays are beneficial to understanding mental health issues because they could find location of tumors that might cause mental abnormalities in a patient. 2. Positron Emission Tomography: Also known as PET, this type of study was the first brain imaging technique that provided images of the brain and its activity rather than just straight faced images. 2-DG is injected into the patient and if the patient is doing an activity while taking this scan, bin about 30 seconds after the injection, the scan will show the brain level that most active. This can be beneficial because it can show if parts of the brain are reacting normally or abnormally to exposures to certain activities and stimulus. 3. Muscle Tension: Muscle Tension would be considered a Biofeedback. This is a method that uses the mind to control a body function that the body regulates automatically. (1) Electromyography is the normal procedure for measuring...

... * There are five major divisions which hold a specific function in the brain. These major divisions or structures are very important and can often be described or compared to neighborhoods or districts due to how they have different locations in the same area. The early development of the brain begins explaining the five major divisions and what each one does in particular. In the vertebrate embryo, the tissue that eventually develops into the CNS is recognizable as a fluid-filled tube. The first indications of the developing brain are three swellings that occur at the anterior end of this tube (Pinel, 2011). These three swellings with time develop into what is known as the forebrain, midbrain and hindbrain. Before birth, the three swellings in the neural tube become five which occur when the forebrain swelling grows into two different swellings just like the hindbrain. The five swellings then make up the brain at birth. These five sections or swellings are known as the Telencephalon, Deincephalon, Mesencephalon, Metencephalon and Myelencephalon. * The Myelencephalon, also known as the Medulla Oblongata, is located in the most posterior division of the brain (Hindbrain). The Mylencephalon is responsible for delivering signals between the brain and the entire body and responsible for reticular formation. Reticular formation is known for its net-like appearance that occupies the core of the brain stem and parts of it play a role arousal as well as other functions like sleep...

...The Brain Crystal Gartner University of Phoenix PSY 240 October 26, 2012 C Hines The brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. It is the portion of the vertebrate central nervous system enclosed in the skull and continuous with the spinal cord through the foramen magnum that is composed of neurons and supporting and nutritive structures (as glia) and that integrates sensory information from inside and outside the body in controlling autonomic function (as heartbeat and respiration), in coordinating and directing correlated motor responses, and in the process of learning. The nervous system is responsible for making decisions and communication within the body. The nervous system categorized into the central and the peripheral nervous systems. The central nervous system consists of the brain and spinal cord while the periphery nervous system consists of numerous nerves. Nerves move from the brain to other parts of the body such as the nose, eyes, face and ears. They also move from the brain to the spinal cord and then to other body parts like legs, stomach and chest among others. Sensory nerves take information from the environment and transmit it to the spinal cord which finally conveys it to the brain for generation of response, which is carried by motor neurons to the other parts of the body. The brain weighs about three pounds and...

...In this case study, Gazzaniga, M.S and Roger W. Sperry studied the split-brain individuals. The researchers were exploring how far can the two halves of the human brain be able to function on their own, and if they could have separate and unique abilities. If we were to study each side of the brain separately, we would have to surgically cut the corpus callosum, which is what connects and communicates the information between the two hemispheres of your brain. In some cases of extreme epilepsy or seizures, this surgery turned out to be successful and they were called “split-brain” patients. The researches wanted to know if the information traveling between the two halves of your brain were to be interrupted, would the right side of your body...

...I have always considered myself a relatively curious person. This is especially true when it comes to the workings of the human brain. For as long as I can remember, I have wanted to understand everything from why I was scared by silly things like the dark to why I only remember certain events to why some people cannot function normally. Of course, at this time I had no idea what the study of the brain was, I just knew I was curious about why people are the way they are. When I consciously recognized my interest in psychology and neuroscience, it was after my brother had his first eye surgery. Everything seemed fine, until his retina started to detach. The next two surgeries left him with double vision and the worst eyesight he had ever had....

...Head injuries are among the most common types of trauma encountered in emergency department (EDs). Many patients with severe brain injuries die before reaching a hospital, with almost 90% of prehospital trauma-related deaths involving brain injury. The prime goal of treatment for patients with suspected traumatic brain injuries (TBI) is to prevent secondary brain injury. Providing adequate oxygenation and maintaining blood pressure at a level that is sufficient to perfuse the brain are the most important ways to limit secondary brain damage and thereby improve the patient’s outcome. Subsequent to managing the ABCDEs, identification of a mass lesion that requires surgical evacuation is critical, and this is the best achieved by immediately obtaining a computed tomographic (CT) scan of the head. Obtaining CT scan should not delay transfer process to a trauma centre that is adept of immediate and definitive neurosurgical management....

(Reiss et al., 1996, p. 1764) This is one of a few studies that utilizes volumetric imaging to “describe cerebral development and morphology” in normal, non-clinically referred children. (Reiss et al., 1996) Process 100 children between the ages of five and seventeen were given MRI scans of their brains. Of these 100 images, only 85 were used in the final data analysis due to 15 not containing the entire cerebrum in the end result. There were sixty-four females and twenty-one males. The mean ages were 10.6 and 10.7 respectively. The difference between the numbers of girls to boys was due to researchers “recruitment of gender-matched normal controls for ongoing studies of female children with specific genetic...

...All of this relates back to Judy. During her incident, she received a hemorrhage in the right temporal lobe, a hemorrhage in the occipital horn of the right lateral ventricle, bleeding in the right frontal lobe, and a subdural hematoma in the left temporal lobe, among generalized trauma across the brain (Apps et al., 2010). The primary link to the mesolimbic system in this situation is frontal lobe damage. When Judy became impaired in this specific region she lost the connection between the PFC and the mesolimbic system, in turn resulting in losing the ability to regulate her reward system effectively. Now, when stimuli reach the VTA and DA is swept along the system, strong urges to act on said stimulus do not reach the PFC, the region that relays if...

...Schizophrenia Disrupts Brain Development Monica Jones Behavioral Science and Research Method Southern University and A&M College Lionel Jolla, MSW, LMSW – Professor November 18, 2015 Abstract I embarked on this project because I am interested in how schizophrenia affects the brain and what researchers have discovered as far as medicine for this condition. I am looking for a phenomenon that explains why this disorder is destroying brain volume and how this process can be stopped. Schizophrenia is a baffling disorder that reduces brain volume. When and how does schizophrenia begin is one of my concerns. It is hard to figure out when, why and how schizophrenia begins because it can occur as early as the neonate stage of life and as late as the geriatric stage in life. When schizophrenia starts to decrease brain volume, is the brain fully developed is another one of my concerns. Brain volume decreases in schizophrenia patients naturally, but the antipsychotic medication is a contributing factor also. The antipsychotic medication has been known to have adverse side effects on the brain volume. Have researchers found a medication that has a less severe effect on schizophrenia patient’s brain volume, is another question I am interested in finding the answer too. Schizophrenia is an unexplainable disorder that offers no specific answer to how it occurs. In this study I am hoping to find that specific answer to this brain crippling disorder. MRI scans have been the...
