Summary:
In this article, the scientists were experimenting with subjects, mostly university students, to study neurofeedback. They have found that NF (neurofeedback) has proven to help aid those with disorders such as epilepsy and Attention-Deficit Disorder (ADHD). Part of the experiment was to ask the subjects to alter electroencephalographic (EEG) rhythms as they were told. There were training sessions prior the two experiments. Some of the subjects however never learned to manipulate the EEG rhythms despite these lessons. They proposed a simple yet accurate way to predict individual performance for manipulating these rhythms. The EEGs being recorded are brain states which is termed NF. There are various training methods for controlling these such as: training of sensorimotor rhythms (SMR), alpha and beta/theta rhythms and their respective ratios, and slow cortical potentials. These methods have not only been used to help treat ADHD but also autism, Asperger’s syndrome, stroke, tinnitus, emotional disturbances, and more. There were two experiments conducted. The first had thirteen participants including five women and eight men. They were all trained to increase the amplitudes of SMRs throughout twenty-five lessons. The second experiment was conducted in an identical manner, with respect to EEG recordings and training instructions, but with five more lessons, making thirty. The second experiment
