The brain like system Using own terminology of systems, we can classify to the human brain like a system, which by means of a process (thought) manages to turn the entrances (mainly sensorial) into exits (action). The simbología to diagramar and to explain the Systems can be consulted in the Annexed A. We can graphically observe this process in panel RN001. PANEL RN001 Process of thought seen from the perspective of the Theory of Systems HUMAN BRAIN We found that diverse stimuli to the brain exist, which then can summarily be called " sensorial perceptions ". The human being is a system that leaves from sensorial stimuli, which uses like entrances (inputs) for his process of thought. The word perception includes nonsingle to the incitaciones that the medio.ambiente also causes in the five senses but to the lucubrations that the own mind of the subject can discern. The brain of the subject is stimulated by the simultaneous interrelation of perceptions, which take to activate the denominated process thought. This it can as well require experiences stored in the memory of the individual, that works in this approach as a file or data base that contains data called in this context " Memories ". The thought process can have like by-product the creation of data to be kept, which will be transformed as well into new memories. Therefore, it is possible to be characterized to the thought as a process of consultation and writing of the data base " memory ". On the basis of these processes it happens the process of processing and planning of the action to takings like result of the intellectual process. This action can be physical or psychic. In the first case, determined muscles of the body are programmed to move in a defined sense. Example: The increase of the room temperature causes in the individual the heat perception and this it directs his actions towards the ingestion of I eliminate not to dehydrate. In the second case, a perception can take to the recovery of a memory of the memory (data base). Example: The perception of a floral aroma causes the memory of a placentera happened last experience in a full field of flowers. The brain this constituted by a vast assembly of called cells neurons, which intercommunicate to each other by means of electrical impulses, by means of the calls sinápticas connections. The neurons form, then, a network where each one of them is a node, interlaced by means of connections that transmit electrical signals. A neuron can receive and transmit electrical signals from and towards several other neurons. Panel RN002 shows east process seen from the optics of the theory of the Systems. PANEL RN002 The then thought physically consists of a series of electrical interactions between the neurons, which act the following as basic: a) To receive Signals: Each neuron receives one or several emanated electrical messages of the adjacent neurons. b) To condition the unloading: The neuron acts like a distributing system of transit that takes the energy transferred until her by means of the action deciphers in a) and decides as of its exits to activate and as no. c) To unload (To emit Answer) and to reinforce connections. The energy is expelled towards the adjacent neurons to which it is connected. Jointly with this, the sinápticas connections are reinforced. This way, a preference of proportional exit to the amount of times settles down that has activated the same one. Following Pagina Previous Pagina
