Networks of Networks in the Brain

This 4 hrs lesson belongs to a wider course on the study of natural neural networks. Its aim is to show how organizing neurons in networks can produce basic cognitive abilities, and how organizing neural networks in networks can produce more complex cognitive abilities. Because brain is a network of networks we hope to demonstrate how cognition may emerge from a biological device.
