Functional magnetic resonance imaging (fMRI) of thoracic spinal cord neurons was used to examine the neural correlates of visceral emotional responses. Participants completed four spinal fMRI runs involving passive viewing (i.e. no movement) and motoric responses to negative or neutral images. Negative images, particularly in the movement condition, elicited robust activity in motoric nuclei, indicating 'action preparedness'. These images also enhanced activity in autonomic and sensory nuclei, thus providing a clear neural representation of visceral responses to emotional stimuli.
采用胸段脊髓神经元功能磁共振成像（fMRI）来检查内脏情绪反应的神经关联。参与者完成了四次脊髓fMRI扫描，包括被动观看（即无动作）以及对负面或中性图像的运动反应。负面图像，尤其是在运动条件下，引发了运动核团的强烈活动，表明“行动准备”。这些图像还增强了自主神经核团和感觉核团的活动，从而为内脏对情绪刺激的反应提供了清晰的神经表征。
