Predictive visuo-motor communication through neural oscillations

dataset from "Predictive visuo-motor communication through neural oscillations" by Benedetto, Binda, Costagli, Tosetti & Morrone Benedetto et al. show that visual sensitivity, BOLD activity in primary visual cortex and functional coupling between visual and motor cortex oscillate at the same theta frequency after a voluntary action. The results suggest that a motor preparation signal resets the phase of endogenous V1 rhythms to implement a flexible but precise coordination. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ data_figures.xlsx contains the data to reproduce the figures of the manuscript: Sheet 1 → figure 1 Sheet 2 → figure S1 Sheet 3 → figure 2 Sheet 4 → figure S2 Sheet 5 → figure 3 Sheet 6 → figure 4 Sheet 7 → figure S3 _______________________ residualData_V1M1.mat contains data to compute correlations between ROIs. "residuals" is a 1x4 cell containing the residuals of the ROIs around the time of each visual stimulus presentation. residual{1} contains data from the 70 ms delay condition residual{2} contains data from the 150 ms delay condition residual{3} contains data from the 230 ms delay condition residual{4} contains data from the 310 ms delay condition each cell has 3 dimensions: dimention 1: trials dimention 2: TRs (from -1 to 4) dimention 3: ROIs (where 1=V1, 2=M1) _______________________ betas_vision_and_action.nii.gz contains the beta maps for the "vision and action" events in the left (overlay 1) and right (overlay 2) hemisphere (figure 1C). Maps report beta-values, masked by fdr-corrected significance. Zero-values indicate that the vertex has a non-significant beta value (or it was not covered in fMRI acquisitions). Maps from both hemispheres were projected to the mirror-symmetric fsaverage_sym template. _______________________ betas_action_for_decision.nii.gz contains the beta maps for the "action for decision" events in the left (overlay 1) and right (overlay 2) hemisphere (figure S1D). Maps report beta-values, masked by fdr-corrected significance. Zero-values indicate that the vertex has a non-significant beta value (or it was not covered in fMRI acquisitions). Maps from both hemispheres were projected to the mirror-symmetric fsaverage_sym template. _______________________ betas_peak_vs_trough.nii.gz contains the difference of beta-values for the peak and trough delays in the left (overlay 1) and right (overlay 2) hemisphere (figure S1E). Maps report beta-values. Zero-values indicate that the vertex has a non-significant beta value (or it was not covered in fMRI acquisitions). Maps from both hemispheres were projected to the mirror-symmetric fsaverage_sym template.本数据集源自Benedetto、Binda、Costagli、Tosetti与Morrowne的研究论文《Predictive visuo-motor communication through neural oscillations》（《基于神经振荡的预测性视运动通信》）。Benedetto等人的研究表明，自主动作产生后，视觉敏感性、初级视觉皮层（primary visual cortex）的血氧水平依赖（BOLD）活动，以及视觉与运动皮层间的功能耦合，均以相同的θ频段频率发生振荡。该研究结果提示，运动准备信号可重置内源性V1节律的相位，从而实现灵活且精准的协调。 ---------------------------------------------------------------------- ### 数据文件详情 1. **data_figures.xlsx**：包含复现论文插图所需的全部数据，各工作表对应插图如下： - 工作表1（Sheet 1）对应图1（figure 1） - 工作表2（Sheet 2）对应补充图S1（figure S1） - 工作表3（Sheet 3）对应图2（figure 2） - 工作表4（Sheet 4）对应补充图S2（figure S2） - 工作表5（Sheet 5）对应图3（figure 3） - 工作表6（Sheet 6）对应图4（figure 4） - 工作表7（Sheet 7）对应补充图S3（figure S3） 2. **residualData_V1M1.mat**：用于计算感兴趣脑区（ROIs）间相关性的数据集。其中变量"residuals"为1×4的细胞数组，存储了各视觉刺激呈现时刻前后感兴趣脑区的残差数据： - residual{1} 对应70ms延迟条件下的实验数据 - residual{2} 对应150ms延迟条件下的实验数据 - residual{3} 对应230ms延迟条件下的实验数据 - residual{4} 对应310ms延迟条件下的实验数据 每个细胞数组均包含3个维度： - 维度1：试次（trials） - 维度2：磁共振成像重复时间（TRs，取值范围为-1至4） - 维度3：感兴趣脑区（ROIs，其中1代表V1脑区，2代表M1脑区） 3. **betas_vision_and_action.nii.gz**：包含“视觉与动作”事件的β映射图数据，覆盖左脑半球（叠加层1）与右脑半球（叠加层2），对应图1C。该映射图报告经错误发现率（FDR）校正后的显著性掩蔽β值，零值表示该顶点的β值无统计学显著性（或未被功能性磁共振成像（fMRI）扫描覆盖）。左右脑半球的映射图均已投影至镜像对称的fsaverage_sym模板空间。 4. **betas_action_for_decision.nii.gz**：包含“用于决策的动作”事件的β映射图数据，覆盖左脑半球（叠加层1）与右脑半球（叠加层2），对应补充图S1D。该映射图报告经错误发现率（FDR）校正后的显著性掩蔽β值，零值表示该顶点的β值无统计学显著性（或未被功能性磁共振成像（fMRI）扫描覆盖）。左右脑半球的映射图均已投影至镜像对称的fsaverage_sym模板空间。 5. **betas_peak_vs_trough.nii.gz**：包含不同延迟条件下峰值与谷值的β值差异数据，覆盖左脑半球（叠加层1）与右脑半球（叠加层2），对应补充图S1E。该映射图报告β值，零值表示该顶点的β值无统计学显著性（或未被功能性磁共振成像（fMRI）扫描覆盖）。左右脑半球的映射图均已投影至镜像对称的fsaverage_sym模板空间。
