Non pyramidal descending motor potential activated by cerebellar stimulation comparison with direct motor cortex stimulation and transcranial stimulation



Non pyramidal descending motor potential activated by cerebellar stimulation comparison with direct motor cortex stimulation and transcranial stimulation



Nichidai Igaku Zasshi 48(3): 243-252



Non-pyramidal descending motor potentials (ND-MP) were recorded from the spinal epidural space on stimulating the cerebellar cortex and dentate nucleus. The NDMP were compared for corticospinal motor evoked potentials which were activated by directly stimulating the motor cortex, and for transcranially stimulated descending spinal cord potentials. The NDMP were considered to originate in the cerebellar nuclei including the dentate nucleus and to pass through the vestibulospinal, reticulospinal, reticulospinal and fastigiospinal system. The conduction velocity of the NDMP (120.2 .+-. 16.2 m/sec) was much faster than that of the cortico-spinal motor evoked potentials (68.8 .+-. 14.7 m/sec) but was the same as that of the transcranially stimulated descending spinal cord porentials (122.3 .+-. 16.3 m/sec). Although the corticospinal motor evoked potentials disappeared after intercollicular transection, the NDMP and transcranially stimulated descending motor potentials did not disappear. Transcranial stimulation is thus proposed to activate a non-pyramidal descending motor potential similarly to cerebellar stimulation.
