There are some cases where plasticity can be useful. For example: if a particular intention is associated with the neural activity while a person lifts their arm, eventually the person can train themselves to trigger the intention just by thinking of lifting their arm (without actually doing it). This is the brain learning to control the intention instead of the action.
