The models and simulations here demonstrate that steady progressing waves are possible in networks whose elements are near SNLC bifurcations. Such networks arise in studies of the neocortex, and cortical waves of this kind have been observed [11,15]. There are many areas of the brain whose function is based on propagation of activity, such as sound location in the nucleus laminaris [3]. It is also possible that propagation of neural activity in the hippocampus is important for navigation and memorization [10].
We have shown here that striated structures can support waves having different speeds which is not possible in single layer structures. These waves in striated structures moving at different speeds can create dynamic patterns with brief intervals of coincidence that are believed to play important roles in brain function [13].
