1337-皮质脊髓疼痛预测模型

from 聊聊Sci

这项研究介绍了一种名为皮质脊髓疼痛强度模式 (CsPIP) 的新型神经影像生物标志物。研究人员通过同步采集大脑和脊髓的fMRI数据,开发出一个能整合全神经轴活动的多元预测模型,旨在更精准地解码人类的疼痛感知。实验结果表明,该模型的预测准确性显著优于传统仅关注大脑的指标,并能有效泛化至电刺激疼痛等不同维度。此外,CsPIP 成功追踪了经皮电刺激神经疗法产生的镇痛效果,展现了其作为治疗评价工具的潜力。在临床应用方面,该模型能够通过静态和动态的神经活动分析,预测慢性疼痛(如肠易激综合征)的严重程度及康复进展。这项研究通过整合脊髓回路的调节功能,为理解疼痛的生理机制和实现精准疼痛管理提供了全新的跨尺度视角。References:Lin X M, Zhang X S, Zhou H, et al.
