ThediscoveryofmicroRNAshasrevealedanunexpectedandspectacularadditional levelof?netuningofthegenomeandhowgenesareusedagainandagainin differentcombinationstogeneratethecomplexitythatunderliesforinstancethe brain. SincetheinitialstudiesperformedinC. elegans,wegavegoneafarwayto begintounderstandhowmicroRNApathwayscanhaveanimpactonhealthand diseaseinhuman. AlthoughmicroRNAsareabundantlyexpressedinthebrain, relativelylittleisknownaboutthemultiplefunctionsoftheseRNAmoleculesinthe nervous system. Nevertheless,we knowalready that microRNA pathways play majorrolesintheproliferation,differentiation,functionandmaintenanceofneu- nalcells. SeveralintriguingstudieshavelinkedmicroRNAsasmajorregulatorsof theneuronalphenotype,andhaveimplicatedspeci?cmicroRNAsintheregulation ofsynapseformationandplasticity.
