Abstract
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.
Keywords

dynamics, neocortex, network symmetry, neurodynamics, pyramidal
