| Research Abstract |
The present research have investigated the effects of water immersion on neural excitability in somatosensory and motor cortical area. In experiment1, we have measured somatosensory evoked potentials during water immersion, and found that water immersion induced the attenuation of SEP amplitude. In experiment 2, we have evaluated short and long afferent inhibition and the neural excitability in motor area, and shown that water immersion decrease SAI and LAI. These results suggested that water immersion affects the neural excitability in somatosensory area and sensory-motor connection.
