The parietal cortex detects and corrects errors in this aspiring tennis player
Where is the error? The parietal cortex knows! - neuroscience news

Practice is needed to acquire new skills. One would for instance need to learn to control one’s own movements, as well as those of a moving target, like when you want to hit a tennis ball. A miss can be caused by your own, untrained, motor system or by an unexpected curve of the tennis ball. As these two errors mean different things to learn, neuroscientists have sought, and found, the brain region that may differentiate between one’s own motor errors and prediction errors imposed by the target. It turned out that Brodmann area 5 in the parietal cortex detects movement errors and provides signals for correction, whereas the neighboring Brodmann area 7 detect target errors. These findings give insight in learning on the basis of correction of errors, and might be used to improve learning methods for robots.
