Spinal cord neurovascular coupling. a Average spinal cord neurovascular coupling (normalized SCBF/LFP ratio) at different stimulus intensities for the anesthetized and non-anesthetized conditions. No significant difference was observed between the lowest stimulus and the succeeding intensities, although lowest and highest intensities tended to show a larger ratio. Also, isoflurane anesthesia did not affect neurovascular coupling. b Individual LFP and SCBF data for each stimulus intensity and each animal, in the anesthetized and non-anesthetized conditions
