Lors d’une simple discussion, échanger avec une personne autour d’un sujet en étant en accord ou en désaccord, ne serait pas du tout la même chose au niveau cérébral ; mais dans les deux cas, cela pourrait être très enrichissant.

Que se passe-t-il dans notre cerveau lorsque nous discutons, notamment si la personne face à nous est d’accord ou, au contraire, en total désaccord avec nos propos ?
