If the brain's physiology is responsible for the way we think, then our psychologies and, therefore, our behaviours may not fit the traditional model that, for example, legal judgements on criminality are made on. If criminals behave as they do because of the physiology of their brain, then the question of whether or not they are responsible for their actions can be reasonably put. However, mainstream opinion still agrees that people are accountable for their own moral decision-making in most cases.
