[Introduction to neuronal plasticity].
Neuronal plasticity is observed throughout animal kingdom. It underlies processes of functional restoration after brain injury or peripheral deafferentation and it also makes learning and memory possible. The paper reviews briefly the conditions which, according to Hebb's rule, are required for neuronal plasticity to occur. It stresses the importance of convergence of signals, coincidence and repetition. The roles of NMDA receptors and neuromodulators are described. The paper reviews current concepts and data concerning anatomical changes that accompany plasticity of cortical representations.
