Unconditional and conditional reflexes

Pavlov discovered that the brain also works under the law of reflex, but my reflexes are not special. These neural connections are formed in the course of life in some circumstances, and therefore were called conditional.
When a dog eats, the food irritates the taste buds of the tongue. From them running pulses in the food centre of the brain, where sensitive cells are transferred to the motor, sending the order to the glands to work. In result of flowing saliva, stands out gastric juice , etc., In the mechanism of such a nervous reflex communication between cells, taking in the information about the taste of food, and the cells that control the secretion of juices, exists from birth. Such innate reflexes Pavlov called unconditional.
If before feeding the dog several times to give, for example, a call, then in the future, one call will cause the branch of saliva. Such facts were known from life for a long time. Since childhood I remember: once in the kitchen began to talk about the plate knife living in the house, the dog and the cat rushed to the kitchen; the sound repeatedly before was accompanied by feeding. Scientists passed by this fact, otdelalas indicating that the animal understands used, etc. I. P. Pavlov spoke strongly against such non-descript explanations and studied this apparently simple fact, found in him a key to understanding the nature of the psychic phenomena.
Pavlov showed that in this case we also have a reflex. Some impact from the outside calls a specific response of the body. Reflex this, however, was formed already during the lifetime due to the fact that several times coincided irritation one centre (hearing) with irritation another (food). Under these conditions between the centres is laid as if the track in the nervous system. The centres are linked, and now irritation one of them is transferred to another. These new reflexes closed the higher animals only in the cortex of the brain. In education, the closure of such new relations and is the main function of this body.
Thanks conditional reflexes animal exclusively subtly adapted to the environmental conditions. So, now the smallest, in themselves harmless sounds, smells, etc. become a signal for other, much more important for an organism stimuli: the approach of a predator, the presence of nearby food, etc. was, for example, that puppies from birth do not respond to the smell of meat. However, once they try it at least once, closed the connection between the olfactory and food centers. Now the animal from a distance rushes to the meat (because of smell dog not to take!).
Thus, developed during the life of countless cortical connections define all of the animals. The implementation of these complex reflexes and is a primitive way of thinking. Enormous value of conditioned reflexes in humans. On the formation and implementation of conditioned reflexes is based not only a thin regulation of physiological ensemble, but also higher mental functions, which we will specifically say in an interview 9.
