Brain Computation Is Organized via Power-of-Two-Based Permutation Logic

The Theory of Connectivity proposes that the origin of intelligence is rooted in a power-of-two-based permutation logic, producing specific-to-general cell-assembly architecture capable of generating specific perceptions and memories, as well as generalized knowledge and flexible actions. Here they show that this power-of-two-based permutation logic is widely used in cortical and subcortical circuits across animal species and is conserved for the processing of a variety of cognitive modalities. The computational logic of modulatory neurons is implemented in the cortex via combining a random-connectivity strategy in superficial layers 2/3 with nonrandom organizations in deep layers 5/6. This simple mathematical logic can account for brain computation across the entire evolutionary spectrum, ranging from the simplest neural networks to the most complex. Read more
