摘要

激动剂-拮抗剂肌神经界面(AMI)是一种新颖的截肢手术,保留了中枢-周围神经系统的感觉运动信号机制。我们的第一项神经影像学研究调查了AMI受试者,重点关注基于任务的神经特征,并显示了本体感觉反馈到中枢神经系统的证据。对大脑休息时自发神经活动的研究有助于非侵入性地表征启动任务反应的空间分布网络。在这项AMI截肢患者静息状态fMRI研究中,我们比较了经胫性AMI截肢患者$(\mathrm{n}=12)$和经胫性传统截肢患者$(\mathrm{n}=7)$以及生物学完整对照组$\boldsymbol{(\mathrm{n}=10)}$的静息状态功能连通性。我们假设AMI手术将诱导功能网络重组,这与传统截肢手术明显不同,也更接近于对照组的神经结构。我们发现AMI患者的神经生理学重构表明,与传统截肢患者相比,AMI患者的突出网络和运动皮质区域之间的耦合明显减少。我们还发现,在传统截肢者自发网络中发现的神经病理特征在AMI受试者的拓扑结构中减少,产生更接近于对照组的连接模式。这些发现为研究人员和临床医生提供了AMI手术对静止大脑影响的关键机制理解,为未来改进假肢控制和体现的研究提供了信息。

Resting State Neurophysiology of Agonist Antagonist Myoneural Interface in Transtibial Amputees
The agonist-antagonist myoneural interface (AMI) is a novel amputation surgery that preserves sensorimotor signaling mechanisms of the central-peripheral nervous systems. Our first neuroimaging study investigating AMI subjects focused on task-based neural signatures, and showed evidence of proprioceptive feedback to the central nervous system. The study of spontaneous neural activity in the brain at rest helps non-invasively characterize the spatially distributed networks that prime task response. In this first study on resting state fMRI in subjects with an AMI amputation, we compared resting state functional connectivity in patients with transtibial AMI amputation $(\mathrm{n}=12)$ and transtibial traditional amputation $(\mathrm{n}=7)$, as well as biologically intact control subjects $\boldsymbol{(\mathrm{n}=10)}$. We hypothesized that the AMI surgery will induce functional network reorganization that significantly differs from the traditional amputation surgery and also more closely resembles the neural configuration of controls. We found that the neurophysiology of AMI subjects reconfigured in such a way that implicated both a salience network and motor cortex region in relationships with significantly less coupling than in subjects with traditional amputation. We also found that the neuropathological signatures found in the spontaneous networks of traditional amputees decrease in the topology of AMI subjects, producing a connectivity pattern more closely resembling controls. These findings provide researchers and clinicians with a critical mechanistic understanding of the effects of the AMI surgery on the brain at rest, informing future research towards improved prosthetic control and embodiment.
