通过脑电遥测采集分析系统,采集分析罗杜杂交犬搜索冰毒过程中脑电变化情况,结果显示,在罗杜杂交犬搜索冰毒过程中,各搜索阶段左右额叶、顶叶EEGδ波(0.5-4Hz)所占比例显著高于其他脑电波;左右额叶β波(16-24Hz)的变化走势明显强于顶叶,但均呈先降后升趋势,左右顶叶β波与左右额叶变化趋势相类似,但变化幅度明显变弱。结果提示,在罗杜杂交犬搜索冰毒过程中,其大脑额叶脑功能区活动高于顶叶功能区,大脑额叶可能主导罗杜杂交犬搜索冰毒整个过程。
The EEG acquisition and analysis system was collected and analyzed by EEG acquisition and analysis. The results showed that in the process of search for methicillin, the EEGδ wave (0.5- 4Hz) was significantly higher than other brain waves; left and right frontal lobe β wave (16-24Hz) change trend was significantly stronger than the parietal lobe, but showed a downward trend, the left and right parietal β wave and left and right frontal lobe changes The trends are similar, but the changes are noticeably weaker. The results suggest that during the search of methicillin in Rhododendrom canine, the activity of the frontal lobe brain is higher than that of the parietal lobe, and the frontal lobe of the brain may lead the search of the ice snout.
