脑磁图测量神经磁性活动具有很高的时间和理论上的高空间分辨率。我们开发了一个实验平台,结合了与脑磁图兼容的非人类灵长类动物的光遗传学技术,作为功能脑图平台使用。在这里,我们展示了已知源的光遗传诱发信号在皮质浅弓状沟和海马区CA3的定位,分辨率为750 微米~3。我们检测到皮质下、丘脑和扩展的颞叶结构中的激活,符合与各自刺激部位相关的已知解剖和功能脑网络。这表明,在一个完整的大脑中,高分辨率定位实验产生的深部来源是可能的。这种方法适用于通过精确的光遗传控制和高分辨率磁源成像技术(MSI)同步记录全脑脑磁图来探索离散脑区之间的因果关系。识别大脑区域之间的因果相互作用对于理解其计算很重要。在这里,作者提出了一个平台,将光遗传学技术与非人类灵长类动物的高分辨率磁源成像相结合,以绘制网络激活图。
Magnetoencephalography measures neuromagnetic activity with high temporal, and theoretically, high spatial resolution. We developed an experimental platform combining MEG-compatible optogenetic techniques in nonhuman primates for use as a functional brain-mapping platform. Here we show localization of optogenetically evoked signals to known sources in the superficial arcuate sulcus of cortex and in CA3 of hippocampus at a resolution of 750 µm3. We detect activation in subcortical, thalamic, and extended temporal structures, conforming to known anatomical and functional brain networks associated with the respective sites of stimulation. This demonstrates that high-resolution localization of experimentally produced deep sources is possible within an intact brain. This approach is suitable for exploring causal relationships between discrete brain regions through precise optogenetic control and simultaneous whole brain MEG recording with high-resolution magnetic source imaging (MSI). Identifying causal interactions between brain regions is important to understand its computations. Here the authors present optoMEG, a platform for combining optogenetic techniques with high-resolution magnetic source imaging in nonhuman primates to map network activation.
