Comparison of Discrete-Trial-Based SMR and SCP Training and the Interrelationship Between SCP and SMR Networks: Implications for Brain–Computer Interfaces and Neurofeedback

The system (1) is for recording electrical signals occurring in a living body and has at least two electrodes (2a,2b) for obtaining a first analogue signal corresponding with an electrical signal occurring in a living body. An analogue/digital convertor receives a second analogue signal corresponding with the first such signal and converts the second analogue signal into a digital signal. A microvolt in the first analogue signal corresponds with a microvolt in the second analogue signal and the analogue/digital conversion unit carries out at least one 18 bits analogue/digital conversion. The system has a micro-controller (5) and a feed (4) for control of the electrodes.
