| Research Abstract |
Firstly, we investigated the brain activation caused by neck flexion and observed following findings: Facilitation of various sensory brain evoked potentials and increment of cerebral blood flows in the relevant brain regions; Increments of amplitude in contingent negative variation and preceding action time of postural muscles during bilateral arm movement; Shortening of P300 latency and increase of P300 amplitude at Pz site during the arm movement; Decrease in negative peak amplitude at Cz cite associated with the anti-saccade; Increase in motor evoked potentials recorded from the upper limb muscles, elector spinae and rectus femoris by transcranial magnetic stimulation to the motor cortex. Furthermore, vibration stimulation effects to the trapezius were found for shortening of reaction times in visually-guided, memory-guided and anti saccades. The shortening of reaction times in the latter two saccades was noticeable.
Next, we investigated the brain activation during saccade caused b

y periodic movements (respiration, mastication, gait, floor oscillation, and repetitive neck flexion). Duration of the movement tasks was 2 or 3 minutes. The former 3 movements were performed in two ways: one was more automatic and another was more voluntary Floor oscillation was adopted as an automatic periodic movement, while repetitive neck flexion as a voluntary movement. Apparent brain activation was observed only for one minute after voluntary periodic movement. Particularly, high brain activation was found during antisaccade after repetitive neck flexion.
Finally, we investigated training effects of brain activation caused by neck flexion and periodic movement, subjected healthy elderly adults and dementia patients. Antisaccade task or touch panel task was adopted as training for 3 weeks or one month. In the elderly, significant training effects were found in antisaccade task, especially with neck flexion, and in touch panel training. In the patients with frontal lobe atrophy, effects by touch panel training were found in antisaccade task. Less
