Plasticity establishes a permanent connectivity of the synapses inmore rigid networks, which when excited, all will communicatetogether. Elasticity maintains an instant connectivity between neuralnetworks by bringing synapses in a suitable communicationdistance. The other way of internal communication in brain isthrough the nerve fibers when two neural network configurations ina far distance can resonate together. The integration of these types ofcommunications is the mean that the brain functions.
