Last night, I gave a one-hour lecture on tips and tricks in bypass surgery at Cadavar Dissection Course of Cerebral Bypass in Mexico City. This is one of activities of Education and Training Committee, World Federation of Neurosurgical Society (WFNS), in which I am working as a Co-Chair. I really appreciate Prof. Diego Mendez Rosito from Mexico and Prof. Luis Borba from Brazil for inviting me as a guest speaker.
