| Research Abstract |
It is well known that the higher-level dorsal stream integrates local motion signals from V1 into global motion. Coherent motion, especially radial optic flow (OF) stimulation, will be able to use for evaluating the global motion defects. On the other hand, the new technique, transcranial direct current stimuli (tDCS), will be established for activating the cortical neurons, selectively. In this study, we proposed the new rehabilitation method for USN to use both tDCS and OF visual stimulation. And we analyzed the long term effects of this method. In the results, the psychophysical recognition level of coherent motion and amplitude and latency of two major ERP components (N170 and P200) in USN patients were slightly recovered. Therefore, this combined rehabilitation approach may be useful for the recovering the cognitive functions of USN patients.
