【摘要】：體感振動(dòng)能夠刺激人的體表感覺區(qū),這種刺激傳輸?shù)杰|體感覺神經(jīng),進(jìn)而影響大腦皮層中央后回及中央旁小葉后部的軀體感覺中樞,從而改變大腦功能狀態(tài)。本研究旨在通過腦電檢測(cè)方法,研究體感振動(dòng)對(duì)大腦功能狀態(tài)的影響。分別對(duì)12名受試者進(jìn)行了20Hz體感振動(dòng)刺激實(shí)驗(yàn),采用相對(duì)功率變化率、Lempel-Ziv復(fù)雜度和基于互信息的腦網(wǎng)絡(luò)等方法。結(jié)果發(fā)現(xiàn),20Hz振動(dòng)使得左前額區(qū)及左前顳區(qū)的腦電信號(hào)產(chǎn)生頻率跟隨響應(yīng);而腦網(wǎng)絡(luò)分析表明:20Hz體感振動(dòng)刺激使大腦右半腦區(qū)的額葉、中央葉、頂葉、顳葉、枕葉之間的信息流傳遞加強(qiáng),大腦皮層趨于興奮。因此,利用20Hz體感振動(dòng)刺激調(diào)節(jié)大腦功能狀態(tài)具有一定可行性。
[Abstract]:Somatosensory vibration can stimulate the sensory region of human body surface, which is transmitted to the somatosensory nerve and then affect the somatosensory center of the posterior central gyrus of the cerebral cortex and the posterior part of the paracentral lobules, thus changing the state of the brain function. The purpose of this study was to study the effects of somatosensory vibration on brain function by EEG. A 20Hz somatosensory vibration stimulation experiment was carried out in 12 subjects. The Lempel-Ziv complexity and mutual information based brain network were used to measure the relative power change rate. The results showed that 20 Hz vibration resulted in frequency following response of EEG in the left frontal region and left anterior temporal region, and the brain network analysis showed that the 20 Hz somatosensory vibration stimulated the frontal lobe, central lobe, parietal lobe and temporal lobe of the right hemispheric region of the brain. The flow of information between the occipital lobes is enhanced, and the cerebral cortex tends to be excited. Therefore, it is feasible to use 20 Hz somatosensory vibration stimulation to regulate brain function.
