Obviously, with distinct interests, which reproduce different proposals and conceptions of what it is to be child and of the necessities that this phase presents. We can search in history some concerns with infancy, as well as with what it involves the slight knowledge of ' ' city sustentvel' ' , ' ' sustentabilidade' ' , to understand such questions better. In elapsing of the times, and mainly, as it discloses to Muller & Redin (2007, p.15), after 2 world-wide war, had, on the part of the state representatives, a concern with the children, the orphans of war. What to make with these small that, alone ones in the world, abandonments in the streets, they could come to be a problem for the future, for the proper society? The authors count on the sprouting of the school and institutions that could help in the control and ' ' adaptao' ' of the same ones to alive the social one. In this construction, she transfers herself to see the child to it as a future project, one ' ' to come-the-ser' ' , as she affirms Miguel Arroyo (2000). It is impossible to deny, therefore, that many scholars of infancy, in this historical passage, have brought for the quarrel the importance of this phase and its validity in the gift. It is not, according to them, what it is for coming, is what they are now, ahead of the world, the family, the school, the shelters, of the streets, of problematic current and the etc. Other advances and changes in the historical passage are the laws and regiments who deal with this social group, even so very still have that to advance, as we bring more ahead. thus, following this quarrel, therefore everything is linked, being part of the one all biggest one, the ideas and action on the urgency of if having a city and world ' ' sustentvel' ' if they spread and they create imaginary a social one that if makes to try to be unanimous, in the same tunning Of this form, Axe (2010), supported in Lefebvre and Acselrad, argues the conflicts generated for this system, that if ' says; ' for todos' ' if makes for some.
First after the passage of the stimulus they are inmodificadas, that is to say, they receive amount they unload and it, obtaining therefore tension zero, second they retain amount and they are modified by each one of the successive passages of the stimulus, which returns more apt them for the conduction from the tension of one to another neuron. These interneurnicos contacts Freud denominate facilitation. The function of the memory is composed by the accumulation of these differentiated facilitations. In as much these facilitations they favor the unloading of the stimulus, serve the primary function. Even there is another process that returns to put to the apparatus concerning this operation: the pain. In the text is described it like most imperative of all the processes, consists of the impression of great amounts of (q), by fault of the teleneuronal system that works like a barrier to the stimuli (q), which does that at system j a smaller amount arrives from this stimulus, the amount reduced causes that concerning this system the unloading takes place in such a way that it arrives at the tension zero – where neurons f appear as permeable as neurons j, producing facilitations such that both systems are compared. Freud outlines the consequences of the experience of satisfaction and the experience of pain the following way: In first two types of neurons are catectizadas that it classifies like and b.
The neurons to correspond to the perception of the object by means of which the satisfaction took ahead. The b corresponds to the reflected movement that followed the specific action. This catectizacin is simultaneous, when a new push of the necessity takes place to and b is simultaneously catectizadas, that is to say, the first neuron in undergoing this activation is a (image of the object) which produces a hallucination that leads immediately to the activation of the neuron b (reflected act) whose consequence is the qualification of displacer produced in W.
