【摘要】 听觉事件相关诱发电位地形图,又称P₃₀₀地形图,可判断大脑认知功能障碍及其严重程度,老年人,尤其是合并脑血管病者在P₃₀₀潜伏期、功率值及其对称性等方面都有明显异常。因此P₃₀₀地形图是一项对老年人智能评估最客观的电生理指标。更多还原

【Abstract】 AERP (P300) mapping can judge gnosia distu rbance and it’s seriousness. P300 mapping of the aged , especially who suffer from cerebrovascular disease, is obvious abnomal in latencies, power symmetry and power. P300 mapping is a best abjective electrophysiologic index to estimate intelligence of the aged.更多还原
