摘要: Abstract The function of descending motor pathways and that ascending sensory in the spinal cord were monitored at same time 120 patients undergoing surgery for scoliosis. Transcranial electrical stimulation cortex was performed simultaneously with tibial nerves popliteal fossae, volleys recorded from two levels using epidural electrodes. Stable recordings both valleys have been obtained all neurologically normal many pre-existing neurological deficits. experimental conditions which resulted reliable explored selected include: a vertex-anode/lateral cathode montage transcranial stimulation, recording evoked corticospinal somatosensory levels, high-pass filter 500 Hz, stable anaesthesia. allows full muscle relaxation use volatile anaesthetics; deterioration to be identified quickly distinguished an artifactual change.
