Significant psychophysiological interaction effects.

Transient alterations were defined as a cold-induced increase in functional coupling between seed region and clusters present when contrasting cold stimulation to the affected limb versus in the CRPS state versus a) the unaffected limb in the CRPS state; b) the affected limb in the recovered state; and c) the unaffected limb in the recovered state. Persistent alterations were defined as regions with a cold-induced increase in functional coupling between seed region present in both the CRPS state (versus unaffected limb) and in the symptomatically recovered state (affected vs unaffected limb). Cluster size for entire clusters, with sub-peak coordinates. Regions indicate nearest (

暂时性改变定义为：当将处于复杂性区域疼痛综合征（CRPS，Complex Regional Pain Syndrome）状态下的患侧肢体冷刺激，与以下三种情况进行对比时，冷诱导的种子区（seed region）与集群（clusters）之间的功能连接（functional coupling）增强的现象：a) CRPS状态下的健侧肢体；b) 康复状态下的患侧肢体；以及c) 康复状态下的健侧肢体。持续性改变定义为，同时在两种对比场景下均出现冷诱导的种子区与集群之间功能连接增强的脑区：一是CRPS状态下（患侧肢体与健侧肢体对比），二是症状缓解状态下（患侧肢体与健侧肢体对比）。全集群的集群大小及次峰坐标。所标注脑区为距离最近的（
