Devices for measuring and giving Neurofeedback Equipment of EEG brainwave activity is not new. Some have been available commercially since the 1970s. The first one that I was introduced to was housed in a wooden box and had an analog meter, a training frequency selector for Alpha, Theta, or Beta, a threshold setting, and audio feedback – very simple. It did not interface with a computer and there was no data storage or report available. This was around 1985. Since then much has changed. Those devices began to be interfaced with computers for better feedback and the added capabilities of data storage and reports.
Other systems have come along that only work with a computer with no feedback on the device that you plug the sensor cables into. Now there are some that work with smart phones and tablets like one called The Muse.
