在这项研究中，我们使用了头皮-颅骨-大脑头部模型的偶极子追踪方法来确定与人类焦虑引起的呼吸频率增加相关的电流源的位置。预期焦虑是在红灯亮起后通过电刺激左手食指产生的。当给予预期焦虑时，受试者的焦虑状态和呼吸频率增加。在平均脑电图，这是由吸气开始触发，正波观察到约350毫秒后吸气开始。在这段时间内，偶极子集中在右颞极，最焦虑的受试者的颞极和杏仁核。这些数据表明，在边缘系统和大脑边缘系统区域存在与焦虑相关的神经活动，这可能与人类的焦虑有关。(C)2000 Elsevier Science爱尔兰有限公司保留所有权利。
in this study, we used the dipole tracing method of a scalp-skull-brain head model to determine the location of the electric current source which correlates with the increased respiratory rate due to anxiety in humans. Anticipatory anxiety was produced by giving electrical stimulation to the left forefinger after the warning red light. While administering anticipatory anxiety, subjects' anxiety state and respiratory rates increased. In averaged electroencephalogram, which was triggered by onset of inspiration, positive waves were observed approximately 350 ms after the onset of inspiration. In this period of time, dipoles were concentrated in the right temporal pole, and the temporal pole and the amygdala in the most anxious subject. This data suggests that there are respiratory-related neural activities in limbic and paralimbic areas which may correlate with anxiety in humans. (C) 2000 Elsevier Science Ireland Ltd.
