The corticospinal direct (D) response to stimulation of the motor cortex exposed for intracranial surgery was recorded in 20 cases from wire electrodes inserted into the spinal epidural space. The D response was obtained from stimulation of restricted areas of the cerebral cortex, that is, the hand, trunk and thigh areas of the motor cortex. The D response was resistant to anaesthesia and unaffected by muscle relaxants. Thus, recordings of the D response are useful for identifying the location of the motor cortex during intracranial surgery under general anaesthesia.
在20例接受颅内手术的患者中，通过将线状电极插入脊髓硬膜外间隙，记录了运动皮质受刺激时的皮质脊髓直接（D）反应。D反应是通过刺激大脑皮质的特定区域获得的，即运动皮质的手部、躯干和大腿区域。D反应对麻醉有抵抗力，且不受肌肉松弛剂的影响。因此，在全身麻醉下进行颅内手术时，记录D反应有助于确定运动皮质的位置。
