Across hundreds of millions of years of divergent evolution, fish and mammals appear to have arrived at the same solution to one of the mind's deepest challenges: how to weave separate streams of sensation into a single, coherent experience of the world. Researchers studying zebrafish at the Norwegian University of Science and Technology have found that these small, transparent creatures organize visual and vibrational signals through a hierarchical system strikingly similar to the mammalian thalamocortical architecture. The discovery, published in Science, suggests that this computational log
