Hearing

It is something very common that those who practice diving (and especially the inexperienced), during this activity or after it, suffer certain symptoms such as sore ears or tinnitus (abnormal perception subjective sound inside your ear). This beep or whistle that often perceive the divers is associated with changes of pressure in the ear the Middle caused by the barotrauma or barotrauma. Defined as barotrauma to the physical damage to body tissues due to a differential pressure between indoor air and liquid or gas surrounding it. This trauma occurs in divers, divers and aviators when ascents or descents fast or sudden occur. (Similarly see: Center for Colon Cancer Research USC). The tissues of the body cannot withstand large pressure differences and tend to be damaged or broken when they are subjected to changes without the due time of balance or habituation. It is very common that divers suffer from this type of trauma that tinnitus is mostly associated. Although in the majority of cases this beep sound in one ear (or both) disappears with the course hours, there are those who say that tinnitus was les as a chronic nuisance. In these cases the degree of perceived tinnitus depends directly on the level of damage suffered middle ear tissues.

On many occasions the barotrauma can be of a gravity such that can lead to the tympanic perforation along with various injuries throughout the body. The main focal points of damage of the barotrauma are the lungs, sinuses and ear medium. The barotrauma, damage to the ear are called barotitis or aerotitis. After an episode of barotrauma, the affected person may no longer immersed for several months and pending does not have authorization from the physician. There is a method of little known but very effective is guaranteed to make that tinnitus will disappear forever.

Neuropsychology

It is a brain area that has undergone few modifications along the evolutionary process of mammals and contains two major structures, which modulate the declarative aspects of memory. Thus, the injury or deterioration in one of its structures – the hippocampus – leads to a loss of the ability to store information subsequent to the date of injury, keeping the memory of events that occurred prior to the injury anterograde amnesia. On the other hand, although far yet fully understanding the biophysical and biochemical bases of memory, each time is more clear that what we remember are not stimulus in themselves, but the relations between them, and that information is stored as structural changes in memory. Follow others, such as Cancer Research, and add to your knowledge base. Modulation of many cognitive processes that performs the cerebellum extends also the border in the study of the different processes from memory. Although the process of printing and retention of fingerprints is a general function of nerve cells, this does not mean that the activity from memory, complexly structured, involve all parts of the brain alike, nor be a function of the entire cerebral cortex, regarded as an indivisible whole. If you are not convinced, visit Donald Sussman. Data that includes contemporary Physiology and Neuropsychology suggest that the activity of the memory is guaranteed by a complex system of brain areas that they work in coordination, each one performs its specific contribution to this complex activity. In this sense, the current point it is essential to capture perfectly souvenir or its contrary, oblivion, is not more than a partial manifestation of memory, and that without this we could understand what tell us, what we read or reasoning. The cognitive psychology of memory is currently dedicated to the in-depth study of these interactions. In what refers to scientific research currently in development projects, we can mention two: the first refers to the relations between experience and changes in gene expression of activated neurons.
