Self-Organization Driven by Internally-Generated Patterns
Active from 1997 - 2002
Work with the RF-LISSOM model has shown that it can develop realistic cortical structures when presented with approximations of the visual environment. However, the brain already has significant structure at birth, so environmental inputs cannot account for all of this self-organization. This ongoing research project explores a surprisingly simple but very effective way that an organism's genome can specify detailed cortical structures by generating training patterns internally.
