In this study, we investigated how empathic neural responses unfold over time in different empathy networks when viewing same-race and other-race individuals in dynamic painful conditions. We recorded magnetoencephalography signals from Chinese adults when viewing video clips showing a dynamic painful (or non-painful) stimulation to Asian and White models' faces to trigger painful (or neutral) expressions. We found that perceived dynamic pain in Asian models modulated neural activities in the visual cortex at 100 ms-200 ms, in the orbitofrontal and subgenual anterior cingulate cortices at 150 ms-200 ms, in the anterior cingulate cortex around 250 ms-350 ms, and in the temporoparietal junction and middle temporal gyrus around 600 ms after video onset. Perceived dynamic pain in White models modulated activities in the visual, anterior cingulate, and primary sensory cortices after 500 ms. Our findings unraveled earlier dynamic activities in multiple neural circuits in response to same-race (vs other-race) individuals in dynamic painful situations.
在这项研究中，我们调查了当观看动态疼痛条件下的同种族和其他种族个体时，同理心神经网络中的同理心神经反应如何随时间展开。我们记录了中国成年人观看显示亚洲和白人模特面部动态疼痛（或非疼痛）刺激的视频片段时的脑磁图信号，以引发疼痛（或中性）表情。我们发现，亚洲模特感知到的动态疼痛在 100 毫秒至 200 毫秒之间调节了视觉皮层的神经活动，在 150 毫秒至 200 毫秒之间调节了眶额皮质和前扣带回皮质的下部，在 250 毫秒至 350 毫秒之间调节了前扣带皮质的活动，在 600 毫秒后调节了颞顶联合区和中颞回的活动。白人模特感知到的动态疼痛在 500 毫秒后调节了视觉、前扣带和初级感觉皮层的活动。我们的发现揭示了在动态疼痛情况下，对同种族（与其他种族）个体的多个神经回路的早期动态活动。
