Schizophrenia Schizophrenia affects the most crucial parts of the brain: the forebrain, the hindbrain, and the limbic system. The forebrain includes the cerebral hemispheres (hypothalamus, thalamus, corpus callosum, and the limbic system). It controls cognition, sensory and motor functions, temperature regulation, hunger, sleep cycles, and emotional expressions. The frontal lobe of the forebrain causes positive symptoms of schizophrenia like delusions. The temporal lobe of the forebrain distorts sounds

The Devastation of Dementia: Pathophysiology and Case Study Introduction Relatively little is known about dementia, a disease which affects over 35 million people worldwide (Norton, et al., 2012). Early signs and symptoms may be confused with the “normal” aging process. Those with the disease often try to cover up their mental decline in the early stages, making early diagnosis even more difficult. Educating the medical community and the general population about the signs, symptoms and

Some important researchers in the development of the biological perspective are: Plato-nativism Darwin- Outlined evolution and the idea of nativism and heredity Jean Baptiste Lamarck-studied heredity Phineas Gage- Brain injury has the ability to affect behaviour II.

Two theories of criminal behaviour and their factors Developmental theories of crime A study performed by a psychologist Terri Moffitt (1993), she described a dual taxonomy of offending behaviour, and she attempted to explain the developmental processes that can lead to a distinctive shape of the age crime curve. Her original views was that the theory is one of the more important articles in criminology and proposes that there are two types of anti-social behaviour offender’s display in society

Where Is Utopia in the Brain? DanieL s. Levine Introduction The designer of utopian societies, whether fictional or real, often confronts the limits of what is possible for members of our species. But how severe or flexible are those limits? The explosive growth of behavioral neurobiology and experimental psychology in the last decade has produced many results on the biological bases of social interactions. This growth suggests that we can now look to science for some partial answers to the question

specialized hair cells respond to any movement of the cochlear fluids. Sound is then converted via the hair cells and transferred to neural signals that is moved through the auditory nerve to the brain’s central auditory complex (contained within the frontal lobe)

cognition such as; memory, perception, thinking, recognition and the human ability to solve problems, ( Jansari, 2010 p.60). Since the second half of the nineteenth century neurologist began studying brain damage in patients, more specifically their research has examined the effect of brain damage and its implication for normal cognitive functions. It has therefore being argued that in order to understand a working system, one must understand how it can fail, (Jansari, 2010 p. 59). This can refine

The cerebral cortex is the largest division of the brain and is where majority of information processing takes place. The cerebral cortex is split up into four main lobes (frontal, parietal, occipital and temporal) which are associated with specific functions, such as processing information in relation to vision, touch, sound, movement and taste. It also contains the prefrontal cortex. This is the thinking centre of the

vulnerable to the effects of heavy drinking. Excessive alcohol consumption affects how our young brains develop. Studies have shown that alcohol consumption negatively affects academic performance and can impair judgement resulting in risk taking behaviours, unsafe or unwanted sex or injury. Our brains continue to develop into our 20’s. Areas of the brain that undergo the most dramatic changes during adolescence are the frontal lobe and the hippocampus.These are areas of the brain that are associated
