| Outline of Final Research Achievements |
In order to clarify the pathology such as hypotonic state and postural disorder of the abdominal muscles seen after brain injury, the mechanism of motor control was investigated. First, intracellular recordings were taken from abdominal muscle motoneurons and the properties of the spinal reflex mechanism were analyzed electrophysiologically. As a result, monosynaptic excitatory postsynaptic potentials were observed only in the Ia group afferent fiber stimulation derived from the homologous muscle. Furthermore, the vestibular inpust to the abdominal muscle motoneurons were analyzed. As a result, excitatory postsynaptic potentials were observed from about 20% of the motoneurons on the ipsilateral and contralateral side to the stimulations of the vestibular nucleus. It was suggested that the abdominal muscles have a unique spinal reflex mechanism and about 20% of the motoneurons received input from the vestibular nucleus.
