Lee Rannals for redOrbit.com — Your Universe Online Neuroscientists have identified a region of the brain that is capable of switching between new and old habits. A new study by MIT neuroscientists has found a wall region of the brain's prefrontal cortex is responsible for moment-by-moment control of which habits are switched on at a given time. “We´ve always thought – and I still do – that the value of a habit is you don´t have to think about it. It...

Patterns of activity in circuits evolve as our behaviors become more habitual Driving to and from work is a habit for most commuters "“ we do it without really thinking. But before our commutes became routine, we had to learn our way through trial-and-error exploration. A new study out of MIT has found that there are two brain circuits involved with this kind of learning and that the patterns of activity in these circuits evolve as our behaviors become more habitual. The researchers...

Researchers can predict your performance on a video game simply by measuring the volume of specific structures in your brain, a multi-institutional team reports this week. The new study, in the journal Cerebral Cortex, found that nearly a quarter of the variability in achievement seen among men and women trained on a new video game could be predicted by measuring the volume of three structures in their brains. The study adds to the evidence that specific parts of the striatum, a collection of...
