Telling the difference between true and false sounds like a relatively straightforward process but a new neuroimaging study by researchers at the universities of Lisbon and Vita-Salute, Milan, has found that, on a neurological level at least, it is surprisingly complex. In the study participants were asked to read a simple sentence and decide whether it was true or false as the researchers gave them an MRI (magnetic resonance imaging) scan. The false statements led to activity in a part of the brain called the right fronto-polar cortex, an area associated with reasoning. The true statements activated regions called the left inferior parietal cortex and the caudate nucleus which deal with analysing language, memory and reward.
