JANUS Architecture for an Artificial Brain: Medical Perspectives.

摘要

In the evolution of the mammalian brain the two-sided nature of the neural motor control and sensory input has been preserved in the architecture of the cerebral matter. The authors believe this fundamental two-sided nature of the mammalian brain to hold a very important clue to the problem-solving capability and method of the higher mammals. The JANUS idea for the design of a robot's brain is to have a two-hemisphere architecture on the macro-level and self-assessing modules of neural networks on the micro-level. At the highest architectural level there is the possibility of conflicts between the opinions of the two hemispheres, which can independently process the same data and generate motor decisions. The halves are connected by a simplified analogue of the Corpus Callosum, through which they can exchange information at various architectural levels. In the paper the JANUS architecture is motivated and described, and they explain how they expect to use this medically-inspired model to contribute to the understanding of neurophysiological rehabilitation, through construction of a visuo-manual prototype, which has two eyes and two arms.
