摘　　要：为了弄清呼吸各相位与听觉和视觉P300波幅、潜伏期之间的关系,可采用oddball范式进行相关研究。结果发现呼吸相位与P300波幅和潜伏期关系密切,不同的呼吸相位所分配的注意资源有所不同。To study the relationship of four respiratory phases and features of P300, oddball paradigm is applied. The results show that the amplitude of P300 on holding breath phase was larger than on non - holding breath on auditory and visual mode, and had distinct difference among all respiratory phases. The latency of P300 showed distinct difference among respiratory phases only on visual mode. All respiratory phases have close relation with P300＇ s amplitude and latency. Different respiratory phase may be assigned different attentive resources.

关 键 词：事件相关电位 呼吸相位 P300
