Fig. 6From: A proposal for bio-synchronized transmission of EEG/ERP dataThe auditory 40-Hz phenomenon. The figure shows four auditory middle-latency responses to four tone-pips presented at a rate of 40Â Hz (25Â ms time interval). On the bottom, the overlapped response represents the coherent sum (i.e., in phase) of the four responses. The figure is adapted from [36]Back to article page
