Examples of Neocortex

model.MARK_II.Neocortex
Neocortex is a tree(undirected graph) of Regions. Each Region in the Neocortex can have as many children Regions as necessary. Each Region can receive input from input SensorCellLayers, a lower Region, or a higher Region. Input to Neocortex: activity of Cells within VisionCellLayer, AudioCellLayer, etc. Output from Neocortex: activity of Cells/Columns within root Region. @author Quinn Liu (quinnliu@vt.edu) @author Michael Cogswell (cogswell@vt.edu) @version July 12, 2014
