What is neurofeedback equipment used for? It is used for assessment, clinical therapy, and performance enhancement/peak performance. There is also medical EEG equipment that is used diagnostically without the purpose of using the EEG measurement therapeutically. I will not be addressing medical EEG equipment in this article. Neurofeedback means that the EEG is being measured and the data fed back to the subject in a way that they can learn to regulate the activity.
