Function of Brain

Brain controls and regulates the actions and reactions of the body. Continuously receives sensory information, rapidly analyzes this data and then responds by controlling the actions and bodily functions. The brain stem controls breathing, heart rate, and other processes independent. The neocortex is the center of higher-order thinking, learning and memory. The cerebellum is responsible for body balance, posture and coordinates movement (Paul, 2005).

Discussion

Neuropsychology

It is, in the broadest sense, the study of relationships between brain function and human behavior. In practice, it is essentially the diagnosis, evaluation and rehabilitation of disorders of the intellectual functions of the brain.

Neuropsychological disorders

There are two main types of disorders:

Acquired Disorders

They correspond to the loss of a function that is normally installed. This is what we observed in adults. In children also, but only after the vesting period of the relevant function (e.g. a brain injured child who loses the language while talking normally).

Disorders Development

These disorders who settled very early in child development (embryonic life, fetal). They result in a "persistent inability to develop a function" (verbal, gestural, visual).Sometimes a brain injury, occurred before birth or in the perinatal period (the period immediately after birth), can be found (e.g. in children with cerebral palsy). But most often it does not show any brain damage.

Language Disorder

The Visual disturbances of cerebral origin

Disorders of gesture or apraxia

The memory disorders

Neuropsychology disorders visual or failures of the visual world of the brain How our brain sees it?  Visual information ends up in our brain first in the occipital areas. At this level, this information is roughed. Three main parameters are analyzed: the form of color and movement. Then from this first analysis, the "what" and "where" will be treated separately. The what? : Is the identification, for example an object, the temporal area.. The where? : This is assessing the position of this object by the parietal area. Specific visual impairment can match the achievement of each of these steps. Main Neuropsychological Diseases

Alzheimer

Alzheimer's disease (also senile dementia of Alzheimer type) - the most common form of dementia, an incurable neurodegenerative disease, first described in 1906 by German psychiatrist Alois Alzheimer. As a rule, it is found in people over 65 years, but there is early Alzheimer's disease - a rare form of the disease. The worldwide incidence in 2006 was estimated at 26.6 million people, and by 2050 the number of patients could increase fourfold

Alzheimer is a progressive disease of the brain characterized by memory loss and cognitive dysfunction. Achromatopsia (colorblindness) is pathology of the visual system that is manifested by a total lack of vision of colors. It can be congenital or acquired following a brain injury; it is called in the latter case of cerebral Achromatopsia. A person with color blindness is called achromatic. It arises as a result of injury or disease of the retina or optic nerve, and most sufferers do not realize. They are infected with blind colors to be skeptical of someone else in their ability to distinguish colors (such as ...
