Silafae has become the main scientific meeting of the Latin American high energy physics community. A special session held in late 2006 was dedicated to the celebration of the 50th anniversary of the discovery of the neutrino. Leon M. Lederman and James W. Cronin, both of whom are Nobel Prize winners, and Pier Oddone were amongst the participants. The session included 22 talks presented on the recent advances of neutrino physics, including experimental and phenomenological results.
