Introduction: An important but under-investigated confound of functional magnetic resonance imaging (fMRI) is body posture. Although it is well established that body position changes cerebral blood flow, the amount of cerebrospinal fluid in the brain, intracranial pressure, and even the firing rate of certain cell types, there is currently no study that directly examines its effect on fMRI measurements. Moreover, fMRI is typically done in a supine position, which often does not correspond to how these processes are performed in everyday settings.

身体姿势对静息状态功能连接的影响

简介：功能性磁共振成像 (fMRI) 的一个重要但未充分研究的混淆因素是身体姿势。尽管众所周知，身体姿势会改变脑血流量、大脑中的脑脊液量、颅内压，甚至某些细胞类型的放电率，但目前尚无直接检查其对 fMRI 测量的影响的研究。此外，fMRI 通常是在仰卧位进行的，这通常与这些过程在日常环境中的执行方式不符。
