以往的研究报道，实时功能磁共振成像（fMRI）神经反馈使用运动想象可以调节几个运动相关领域的活动。然而，在不同的运动相关的目标区域使用相同的实验方案，这些调制效果的差异仍然没有得到阐明。本研究旨在比较神经反馈对初级运动区（M1）和腹侧运动前区（PMv）的影响。在纳入的参与者中，15人从左侧M1接收血氧水平依赖（BOLD）信号，其他15人从左侧PMv接收信号。两组都被指示尝试通过执行或想象右手握紧运动来增加神经反馈评分（NF评分），该评分反映了目标区域的平均激活水平。结果表明，在想象条件下，PMv组左侧M1失活，而M1组则无; PMv组左侧PMv激活，而M1组则无。我们的发现表明，来自不同运动相关区域的神经反馈对大脑活动调节有不同的影响。
Previous studies have reported that real-time functional magnetic resonance imaging (fMRI) neurofeedback using motor imagery can modulate the activity of several motor-related areas. However, the differences in these modulatory effects on distinct motor-related target regions using the same experimental protocol remain unelucidated. This study aimed to compare neurofeedback effects on the primary motor area (M1) and the ventral premotor cortex (PMv). Of the included participants, 15 received blood oxygenation level-dependent (BOLD) signals from their left M1, and the other 15 received signals from their left PMv. Both groups were instructed to try to increase the neurofeedback score (NF-Score), which reflected the averaged activation level of the target region, by executing or imagining a right-hand clenching movement. The result revealed that during imagery condition, the left M1 was deactivated in the PMv-group but not in the M1-group, whereas the left PMv was activated in the PMv-group but not in the M1-group. Our finding indicates that neurofeedback from distinct motor-related regions has different effects on brain activity regulation.
