先前的研究表明，情绪刺激在大脑中得到优先处理。在目前的研究中，功能磁共振成像被用来确定是否情绪特异性反应是在颈脊髓检测。在被动（即，非运动性）的图像感知，在左背侧和右腹侧脊髓中检测到响应于负面情绪刺激的活动;然而，这种模式在响应于中性和正面刺激时被逆转。重要的是，在积极的运动反应的图像，有更大的活动，在腹侧颈脊髓在回应负面情绪刺激比中性刺激。这些结果表明脊髓对负面情绪图像的优先运动反应，可能表明对威胁的反应增强。(C)2011 Elsevier Inc. All rights reserved.
Previous research has demonstrated that emotional stimuli receive preferential processing in the brain. In the current study, functional magnetic resonance imaging was utilized to determine if emotion-specific responses are detectable in the cervical spinal cord. During the passive (i.e., non-motoric) perception of images, activity was detected in the left dorsal and right ventral spinal cord in response to negative emotional stimuli; however, this pattern was reversed in response to neutral and positive stimuli. Critically, during active motoric responses to images, there was greater activity in the ventral cervical spinal cord in response to negative emotional stimuli than to neutral stimuli. These results demonstrate preferential motor responses to negative emotional images by the spinal cord, likely indicating an enhancement of activity in response to threat. (C) 2011 Elsevier Inc.
