Wave theory of large-scale organization of cortical activity

A two-layer structure of neural tissue modeled as a continuum consisting of purely excitatory and inhibitory cells supports a complex system of growing modes. The wavelengths of the favored nodes, larger than synaptic connection ranges, can be controlled by a variable delay in interlayer signals. Since the continuum regions under consideration are themselves neural networks, we argue that this organized, large-scale activity inherent in the neural material is sufficient to support cognitive phenomena.
