One more year, Barcelona celebrates the World Brain Awareness Week 2010 in its 15th anniversary. Between 15 and 21 March, the Barcelona Science program, along with the Centre for Genomic Regulation, the Barcelona Institute of Education and the collaboration of numerous research centres, organizes a special program for schools and proposals for the general public, adding to this initiative, which emerged from the researchers themselves and which followed in over 72 countries, with the aim of publicizing the efforts being made in the study of human brain to understand its operation.
