Schizophrenia Introduction *Show Slide 1* Schizophrenia is a little known mental disease that affects a small percentage of people throughout the world. The human brain is the most complex organ in the human body, and it is hard to decipher what exactly causes social capability, and overall mental health to deteriorate. Schizophrenia is an extremely mysterious disease, that strikes the interest of many people. Today I am going to inform you all about one of the most commonly

THE USES OF REASON by Jonah Lehrer The summer of 1949 had been long and dry in Montana; the grassy highlands were like tinder. On the afternoon of August 5—the hottest day ever recorded in the area—a stray bolt of lightning set the ground on fire. A parachute brigade of firefighters, known as smokejumpers, was dispatched to put out the blaze. Wag Dodge, a veteran with nine years of smokejumping experience, was in charge. When the jumpers took off from Missoula in a C-47, a military transport plane

and detects the local increase in signal (BOLD contrast) to demonstrate activation of certain areas in the brain. Fetal fMRI has been used to evaluate response to vibroacoustic and visual stimuli with some success, demonstrating a temporal and frontal lobe activation, respectively. Evaluation of resting-state network (RSN) connectivity in normal and pathological conditions in the fetus may help in judging the functional framework and severity of detected abnormalities. Studies have yet to include

(Dryden-Edwards, 20011). When you think of schizophrenia, words like madness and crazy come to mind. It is a disease that is made up of many complex and diverse symptoms, which often overlap with other psychiatric disorders (Pinel, 2009). Schizophrenia affects about 1% of the population. It generally starts between late adolescence and early adulthood. Men are statistically affected with schizophrenia 1 ½ times more than women. There are five types of schizophrenia: paranoid schizophrenia, disorganized

drugs, may interrupt neurodevelopment and associated cognitive and behavioral functioning” (p. 394). Drugs affect the development of the hippocampus and prefrontal cortex in adolescents. Both of these structures are of vital importance to adolescent brain development because they are part of the “limbic system, which supports social and emotional functioning and works with the frontal lobes of the cortex to help us think and reason” (Broderick & Blewitt, 2015, p. 58). Adolescents who are addicted

Brain imaging techniques Introduction to brain imaging techniques and other methods A number of techniques are available to investigate the question of how and where in the brain particular perceptual and cognitive processes occur. Tasks or tests can be devised that place varying levels of demand on the cognitive, sensory or motor capacities of the participant being tested. Performance of these tasks is then correlated with physiological measurements, and on the basis of these results, we may go

we must then look even closer to the actual biology of the neural network to examine how learning and language develops in order to assist in the therapy of aphasics the world over. Broca's area is a portion of the brain in the left temporal lobe which has been attributed to the process of speech. The term “aphasia” is derived from the Greek, aphatos, meaning “without speech”; although not all forms of aphasia silence the aphasic. As opposed to a learning disability which one grows up with

The purpose of this report is to explain what hypokinetic dysarthria is and to establish an evidence-based treatment plan for a patient with the disorder. Hypokinetic dysarthria is a motor speech disorder that is caused by damage to the basal ganglia motor circuit. The basal ganglia motor circuit is made up of the striatum, which is composed of the caudate nucleus and putamen, the lentiform nucleus, which is composed of the putamen and the globus pallidus. The substantia nigra and the subthalamic
