FIG. 910. A.P.J. 192 days after injury. Further increase in the activity of 6th and yth
intercostal spaces. Activity is elicited by a breath of less than 0-5 litre, which in the
previous figures did not produce any activity.
The outstanding feature of the results obtained was the difference in the response of
intercostal activity to the stimulus of breathing between the immediate and later stages
of traumatic paraplegia. During spinal shock, it was difficult to record action potentials
