摘要

目的:探索知觉竞争现象激活的大脑功能部位。方法:运用功能核磁共振方法

使用区组设计的刺激呈现序列

提取并比较Necker立方体的内源性翻转和外源性翻转的信号。结果:功能核磁共振的结果显示

在双侧额上回和额中回内源性翻转和外源性翻转有显著的差异的。结论:额叶皮质可能是产生知觉翻转神经生理过程的功能部位。

Abstract

Objective:We try to examine the hypothesis that perceptual reversal is function of frontoparietal cortex. Methods:We employed block design in functional MRI

extracted event signal of endogenous reversal of Necker cube and compared with that of exogenous reversal. Results:Functional MRI revealed that spatial varieties were significant in bilateral superior and middle frontal lobe. Conclusion:Perceptual reversal may be the function of frontal cortex.
