The EEG click is a Click board™ that allows monitoring of brain activity. Although not suitable for clinical examination, it is quite sufficient to allow some insight into brain activity. EEG click is equipped with a high-sensitivity circuit which amplifies faint electrical signals from the brain, allowing them to be sampled by a host MCU.
This Click board™ can be used with the set of silver-chloride electrodes.
Monitoring brain activity has gained its popularity lately, due to the fact that many commercially available integrated circuits emerge on the market almost daily. High-performance instrumentation amplifier ICs are affordable, making applications such as EEG click possible. The EEG training, a technique of mental training method which makes the trainee consciously aware of the general activity in the brain is one of the applications where EEG click can be very useful. It can be also used for experimentation and development of brain-machine interface applications, or for simple monitoring of the brain activity.
What is EEG?
Electroencephalography is a method used to record the electrical activity of the brain. This is a non-invasive method which uses a number of electrodes placed along the scalp. EEG measures voltage fluctuations which appear as a result of the ionic currents within the neurons of the brain. The measurement can be focused either on event-related potential changes (ERP) or on the spectral content of the signal, collected during a certain period. EEG is most often used to diagnose epilepsy, which causes abnormal changes in EEG readings.
