色差刺激对大脑激活模式的影响
Impact of color difference stimuli on brain activation patterns
摘要
Abstract
Color difference plays a crucial role in target detection.The objective of this study was to investigate the impact of color difference magnitude on the human brain.A 32-channel electroencephalogram(EEG)system was used to collect EEG signals from 30 participants while they viewed stimuli with varying levels of color difference.The results revealed that the amplitudes of the P1 and N1 components in the large color difference group were higher than those in the small color difference group.Furthermore,stimuli with larger color differences led to more persistent energy increases in the EEG signals within the θ and α frequency bands.The analysis suggests that stimulation with larger color differences enhances the brain network's information transmission capabilities,with low-frequency EEG signals showing increased sensitivity to these color difference stimulations.By inputting the topological parameters of the brain network across each frequency band into a decision tree classifier,a classification accuracy of 86.67%was achieved.This research offers valuable insights for advancing intelligent target search methods.关键词
