Real-time detection of precise EMG onset for synchronisation of an EEG averager.
The decision making process by a human observer during visual observation of an EMG waveform has been modelled by electronic methods. EMG onset times were detected with greater precision than is possible with simple threshold voltage comparison, since the threshold voltage detection levels can be set below peak background and artefact amplitudes. The increase in the correlation of each EMG with the corresponding cortical events results in a more accurate synchronisation pulse in average movement potential analysis than has been previously available.
