Abstract : A wave propagation study was completed to determine the in vivo dynamic material properties of the dura mater in mongrel dogs. A portion of the thoracic spinal cord was exposed by laminectomy. The dog was artificially respired after its muscles were paralyzed to prevent any jerk reflex initiated by the spinal cord during the experiment. In the pressure wave experiments, sinus-oidal pressure signals were induced on the in vivo and in situ spinal cord with a probe attached to an electromagnetic vibrator. At two other locations, signals were monitored by pressure transducers pressed gently against the cord. (jes)
