The brain of slow learners may not be able to process information sufficiently say researchers. Scientists trained the subjects' sense of touch to be more sensitive. In subjects who responded well to the training the EEG (Electroencephalography) revealed characteristic changes in brain activity more specifically in the alpha waves. These alpha waves show among other things how effectively the brain exploits the sensory information needed for learning. ‘An exciting question now is to what extent the alpha activity can be deliberately influenced with biofeedback’ said Hubert Dinse from the Neural Plasticity Lab of the Ruhr-Universitat Bochum who led the study.
