When gestures or words are produced and perceived repeatedly by the infant, cell assemblies develop which represent these building blocks of cognitive processing. Cell assembly activity may be reflected by high-frequency brain responses, such as synchronous oscillations or rhythmic spatiotemporal activity patterns in which large numbers of neurons participate. In recent MEG and EEG experiments, differential gamma-band responses of the human brain were observed upon presentation of words and pseudowords. These findings are consistent with the view that fast coherent and rhythmic activation of large neuronal assemblies takes place with word but not pseudowords. In case of doubt or difficulty, consult your system manager.
