Le cerveau en constante reconstruction: Le concept de plasticité cérébrale

Abstract

Brain construction is based on a series of processes including cell differentiation, neuronal migration, axonal guidance and formation of neuronal connections. These processes are tightly controlled by our genetic background. Nevertheless, it is now clearly established that affective and sensorial individual experience lead to multiple possibilities of brain rearrangement. This cerebral plasticity is largely observed during brain development but is also tremendously active throughout adult life. Our personal history therefore constantly lead to subtle structural and functional modifications of our nervous system which will be the support of the high diversity of our thought and our behaviours.
