    Department of Neurobiology, Duke University Medical Center, Durham, NC 27710, USA
    Neuron 57:930-41. 2008

    The John B Pierce Laboratory, Department of Psychiatry, Yale University School of Medicine New Haven, CT, USA
    Front Syst Neurosci 5:99. 2011

    Albino J Oliveira-Maia
    Departamento de Biologia Experimental, Faculdade de Medicina, Universidade do Porto Porto, Portugal

    Xueying Ren
    The John B Pierce Laboratory New Haven, CT, USA
    Front Integr Neurosci 3:12. 2009

    The John B Pierce Laboratory, New Haven, CT 06519, USA
    Curr Biol 23:878-83. 2013
