An international team of investigators from Brazil,Scotland and Germany is expanding the research base on the brain's complex suite of connections known as neural networks using computer simulations and a technique called cluster analysis. Basically, they built a computer model of a cat brain's corticocortical network separated into 65 areas and connected by fibers of different densities. The areas were separated into four clusters, or cognitive regions: visual,auditory, somatosensory-motor, and frontolimbic.
