Ventilatory and circulatory responses at the onset of voluntary exercise and passive movement in sprinters.

The purpose of this study was to clarify the characteristics of ventilatory and circulatory responses at the onset of voluntary exercise and passive movement in sprinters. Eleven male university sprinters and 11 male untrained subjects participated in the present study. Voluntary exercise consisted of leg extension-flexion movement for 20 s with weights corresponding to 5% of each subject's body mass attached to each ankle.

Electroencephalographic dipoles of spikes with and without myoclonic jerks caused by epilepsia partialis continua.

We used electroencephalographic (EEG) dipole analysis to investigate the generators of spikes with and without myoclonic jerks in a 12-year-old patient with epilepsia partialis continua secondary to left parietal cortical dysplasia. We recorded EEG and right wrist extensor electromyography (EMG) and collected 42 spikes with jerks (jerking spikes) and 42 spikes without jerks (nonjerking spikes). We applied a single moving dipole model to the individual and averaged spikes.
