Brain is a portion of the central nervous system contained within the skull. The brain is the control center for movement, sleep, hunger, thirst, and virtually every other vital activity necessary to survival. All human emotions including love, the brain controls hate, fear, anger, elation, and sadness. Memory is usually considered a diffusely stored associative process that is, it puts together information from many different sources. Although research has failed to identify specific sites in the brain as locations of individual memories, certain brain areas are critical for memory to function. Immediate recall the ability to repeat short series of words or numbers immediately after hearing them is thought to be located in the auditory associative cortex. Short-term memory the ability to retain a limited amount of information for up to an hour is located in the deep temporal lobe. Long-term memory probably involves exchanges between the medial temporal lobe, various cortical regions, and the midbrain. (Thompson, Paul, 2002)
Schizophrenia is a multifaceted sickness, and no single cause has been found. The brain is secured by quite a few highly developed defensive mechanisms. The bony cranium, the surrounding meninges, and the cerebrospinal fluid all contribute to the mechanical protection of the brain. In addition, a filtration system called the blood-brain barrier protects the brain from exposure to potentially harmful substances carried in the bloodstream. Brain disorders have a wide range of causes, including head injury, stroke, bacterial diseases, complex chemical imbalances, and changes associated with aging. Research has examined possible abnormalities in brain structure or function.
A current, comprehensive, summary of such studies noted that findings were multifarious and often conflicting; with the only entrenched structural abnormality being enlarged lateral ventricles (fluid-filled spaces within the brain)........
