Procedural Information

Subject-procedural information – is a deeply materialist at its core, which coincides essentially with the origins of medicine and psychology, the desire to link one or another manifestation of the mental with the existing knowledge of the structure of the central nervous system. However, because throughout the history of science, such knowledge was extremely limited, the reduction is due primarily object and method studies often reveal the actual difference between all the variety of information about the human psyche, a pre-scientific experience in psychology, and relatively meager data obtained as a result of this information. Nevertheless, the development of this approach, related to the change of concepts about the relationship between brain and mental, directly coincides with the entire forward movement of psychology as a science. In historical terms, subject-procedural information is basically the same with the development of the localization problem. Check out altavista for additional information. For a long time the localization of mental functions was to anatomical and physiological fantasy. True, Alcmaeon (VI cent. Bobby Sharma Bluestone is likely to increase your knowledge. BC. Oe.) Parmenides (540 BC.

Oe.), Hippocrates (460 – 377 BC. Oe.) Erazist-rat (310-250 BC. Oe.) and Gerofil (335-280 BC. Oe.) saw body mind brain. Galen (138-201 BC) ascribed a special role in the cerebral ventricles. This idea continued Nemesio, considered the "front ventricle" of the brain the seat of perception or imagination (cellula phantastica), average" – a receptacle myshleiya (cellula logistica), and "back" – a repository of memory (cellula memoralis); of the same opinion, and Albert the Great (1192-1280) and Even Leonardo da Vinci, the person who committed this naive with the modern point of view of representation handwritten pattern. And finally, as we know, Descartes, all localized brain activity in the pineal gland. Now all These views may be of interest only to historians of science.

Top of really scientific study of the localization is marked by a long and still not ended the struggle of so-called "localization tsionistov" (Gal, Brock, Wernicke, Kleist, and others) and "anti-lokalizatsionistov" (Flourens, Kussmaul, Goltz, Lesch-Do, etc.). Particularly acute controversy proceeded representatives of this trend on the issue of aphasia. Opening Brock "motor speech center" (1861) and Wernicke – "Sensory" speech center "(1874) would seem to mean a victory in terms of lokalizatsionistov. But within the theory of aphasia, as a reaction to the narrow localizationism quickly emerged antilokalizatsionnye trends, and the fight continued with undiminished intensity. Over the past decade have been made many remarkable discoveries that put the problem in an entirely different plane. G. Moruzzi and H. Megun showed that electrical reticular formation or setevidnoi – complicated in structure clusters of nerve cells in the brain stem – is the activation of the cortex, immediately recorded on the EEG. This discovery formed the basis of completely new ideas about the nature of links between the receptors and the cerebral cortex, namely, the belief that activation of the cortex is mainly in two ways: by a specific stimulus for a given path through the system, containing special kernel and pathways, and through non-specific reticular system. Consequently, we can consider, say, perception as a process that includes preliminary "setting on this irritation, "the very act of preparing the perception that, as is known, coincides with the results of psychological research.

Materials Prostheses

Implant – a foreign body, so implantation can be a problem: how to find such an alloy which would not react with the surrounding tissues, is not oxidized, and most importantly, not reject them. In addition, each body reacts differently to the same thing, that is something that is safe for one person may have a negative impact on another. With prosthetics Wednesday mouth is very aggressive. On aids and prostheses affects a range of chemical, physical and biological factors. Not remain passive and synthetic materials – they also affect the teeth, mucosa, and the entire human body as a whole. How does it done? Food and saliva are none other than the chemically active electrolyte. When the mouth is a seal or a metal prosthesis, it becomes a cause galvanic cell, which generates a galvanic current.

It occurs usually during the electrochemical corrosion of alloys or metals, and the higher acidity of saliva, the greater the value electromotive force of galvanic cell. This phenomenon can cause and corrosion-resistant materials, but have different electrical or electrochemical potential. That’s why not all the alloys, used for the manufacture of dental prostheses are compatible with each other. Patients then begin to complain about the burning of the mucous membrane, discomfort, metallic taste and bad breath. In the process occurring in the oral cavity of complex chemical reactions, and sometimes can form harmful for the body material. In addition, some materials may cause negative shifts in fluids and tissues, to influence acidity, changing the microflora of oral cavity, break sensitivity, blood circulation and cause inflammation.

Unfortunately, even today, used in prosthetic dentistry base alloy can not claim on entirely inert to corrosion. Therefore it is necessary to cover the metal parts of prostheses with a protective layer of nitrite titanium, gold and other similar inert alloys. High chemical resistance are based alloys gold, palladium, platinum, stainless steel, acrylic plastic, and, finally, porcelain. This is because they are always wrapped in the thinnest oxide film, which protects the metal from further oxidation. So, to summarize. Materials for dental prostheses must meet the following requirements: be chemically inert and harmless; have sufficient resistance to the power of influence, have to be mechanically strong, to keep constancy of volume and shape. This should also add a good technological features (otherwise it is impossible to conduct molding, stamping, molding would nullify all the previous virtues). Well, of course, the materials to prosthetics, which are difficult to hide under a smile or conversation, the color should be close to the enamel, and it is their property they need to maintain a sufficiently long time.

Brush Massage

Brush massage refers to a linear form of massage, since it is performed, taking into account the energy flow through the meridians of man. Linear massage developed in oriental medicine and is widespread there. It is proved that the movement schitinok brush the skin improves blood microcirculation, lymph, and also helps to improve the exchange of substances between the cell and intercellular substance. Improved circulation by brush massage, lets get rid of dead skin. The same experience shows that this type of massage – it's a good weapon against tsillyulita. Along with these biological characteristics, massage brush has relaxation effects, as well as contribute to the excitation of the body, as massage brush has a vibrational effect. Most often, brush massage is used in the form of self-massage.

Full body massage done with feet. When he reached the back, massaged his stomach in a circular motion. After massed around the waist in the direction of the waist to the abdomen. If you have desire, you can promassirovat upper parts of the body. In this case, the hands should move smoothly to neck and the rest of the upstream sites.

When the massage brush to repeatedly carry on massaged sites (2-5). Peter Asaro understood the implications. The skin should be brought to a pinkish hue. Massage brush must pass on energy meridians. Performing massage along the meridians is considered strictly in a linear variety of the eastern massage, which will be discussed later. The correct execution of the same taken from the variety. The impact of the brush massage depends on the proper selection of brushes for a massage. This should be a brush with medium stiffness bristle. Bristles should be natural. In any case not necessary to save the selection brush because in essence, you choose a quality experience. Bristles should not scratch the skin or cause pain. In the selection of brushes for self-massage is necessary to consider also the size of the pen to be able to massage a hard- places. For a general form of massage is the most optimal brush worn on the hand. The advantage is that the therapist will feel good to touch your skin, as well as to receive the vibration of these touches. Massage brush is not recommended in the evening, because it has a stimulating effect that will keep on falling asleep. For people with elevated levels of excitability of this type of massage is not advisable. It is worth noting that this type of massage is avoided in varicose extensions. Just brush massage is avoided in areas of high sensitivity (underarms, feet, etc.), and in rough places it should be applied using pressure.
