We had a great opportunity recently for collaborating with Ole Kiehn [ed. note: peer-reviewer 2012] and his lab at the Neuroscience Department to implement our research projects with virus tracing technologies. This will without doubt have a significant impact in the lab for different projects aiming at characterizing genetically distinct populations of sensory neurons involved in the motor circuits. Thanks also the Meletis and Carlén labs [Marie Carlén, also a Ragnar Söderberg fellow in medicine 2012] for providing us with the virus. Many good things is happening in the lab right now!
