Study Reveals Evolution at Work: Analyses elucidate a part of the brain particular to primates

Feb 27, 2014

New research by MCDB’s Kenneth S. Kosik, Harriman Professor of Neuroscience, reveals some very unique evolutionary innovations in the primate brain. In a study published online today in the journal Neuron, Kosik and colleagues describe the role of microRNAs — so named because they contain only 22 nucleotides — in a portion of the brain called the outer subventricular zone (OSVZ). These microRNAs belong to a special category of noncoding genes, which prevent the formation of proteins.
