abstract

  • This commentary summarizes the research presented during the symposium "Examining the genetic and neural components of cognitive flexibility using mice" at the annual meeting of the International Behavioral Neuroscience Society 2011. Research presented includes examining: 1) Corticostriatal networks underlying reversal learning using GluN2B knockout mice, cFos expression, and in vivo electrophysiological recording; 2) Cerebellar contribution to reversal learning using mutants with Purkinje cell loss and in vivo electrochemical recording; 3) Parvalbumin contribution to reversal learning and set-shifting using PLAUR mutants and in vitro recording to examine fast-spiking interneurones; and 4) Alpha 7 nAChR contribution to reversal learning, set-shifting, motivation, and the 'eureka moment' of rule acquisition. It is proposed that these studies revealed more about the neurobiology underlying these behaviors than could be discovered using pharmacological techniques alone. Together, the research presented stressed the importance of exploring the genetic contribution to neuropsychiatric disease and the important role that the mouse, coupled with robust behavioral measures, can play in understanding neurobiology underlying cognitive flexibility.Copyright © 2011 Elsevier Inc.
