OBJECTIVE Median nerve somatosensory evoked potentials (SEPs) may be altered in patients with cerebral tumors. In rare cases cortical responses may be increased, but the significance of this finding remains unclear. METHODS We investigated 3 patients in whom an epileptic seizure was the only neurological symptom of a cerebral tumor located near the central sulcus. We studied median nerve SEPs, motor evoked potentials in abductor digiti minimi muscle, and long-loop reflexes in abductor… CONTINUE READING
