(Medical Xpress)—A pair of researchers with Universidade Federal do Rio de Janeiro has found that the degree of folding of mammalian brains follows a simple mathematical relationship. In their paper published in the journal Science, Bruno Mota and Suzana Herculano-Houzel describe how they came up with the math and its implications regarding the developmental and evolutionary origins of brain folding. George Striedter and Shyam Srinivasan with the University of California offer a Commentary piece on the work done by the duo in the same journal issue.
