Estimates of phase velocity using scalp recorded data are shown to be consistent with a global theory of EEG in which waves are partly transmitted along corticocortical fibers. General features of neocortical dynamics and their implications for theoretical descriptions are considered. Such features include multiple scales of interaction, multiple connection lengths, local and global time constants, dominance of collective interactions at most scales and periodic boundary conditions. Cognitive events may be directly related to the continuous forming and reforming of local and regional circuits which are functionally disconnected from tissue involved in global operation.
