Macroelectrophysiological recordings reflect the activity of large-scale neuronal assemblies and have the potential to index information processing changes during development. A body of knowledge is beginning to emerge that suggests that the phase locking of frequency specific, neuro-oscillatory activity within and between neural assemblies may underlie the processes whereby the brain organizes and communicates information [22, 33, 77-79]. Phase locking of event-related oscillations (EROs) represents a methodology whereby neuronal synchrony can be quantified and compared among experimental conditions in both humans and animals providing thereby a translatable measure with which to explore the neural basis of the behavioral changes associated with development.
