Abstrakt		Typical latency of an individual limb muscle response to magnetic or electric stimulation of the human cortex is in the range of 10-50 ms. For the latency variability, i.e., jitter studies, a resolution of at least 20 micro s is needed. Commercially available EMG equipment needs cutstom-designed upgrading to allow for such studies. Two solutions were designed: (1) a hardware unit allowing an adjustable delay of data acquisition after the delivered stimuli; and (ii) diverting of the amplified biological signal and the EMG eqipment trigger to an ecternal computer equipped with an analogue-to-diginal conversion (ACD) module. Custom-designed software made fast ADC possible during the whole period of data acquisition. Both concepts were applied to a Vickers medical Mystro electromyograph, and have been successfully used in the Ljubljana (Slovenia) Institute of Clinical Neurophysiology for the last 2 years.
