A new paper by Zoltán Toroczkai, professor of physics and concurrent professor of computer science and engineering at the University of Notre Dame, and his collaborators provides a predictive model of cerebral cortical connectivity at the interareal level. The study was published in the Oct. 2 issue of the journal Neuron.

The cerebral cortex is responsible for all the sensory, motor and cognitive functions of an individual and is arguably the most powerful known supercomputer. Read More
