Aristotle thought that the function of the brain was to cool the blood. That seems ludicrous now; through neuroscience, we know more about the brain and how it works than ever before.
An international group of neuroscientists has sliced, imaged and analysed the brain of a 65-year-old woman to create the most detailed map yet of a human brain in its entirety (see video at bottom). The atlas, called 'BigBrain', shows the organization of neurons with microscopic precision, which could help to clarify or even redefine the structure of brain regions obtained from decades-old anatomical studies.
