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Morrone发表的《基于神经振荡的预测性视运动通信》（Predictive visuo-motor communication through neural oscillations）研究。 Benedetto等人的研究表明，在自主动作发生后，视觉敏感度、初级视觉皮层（primary visual cortex）的血氧水平依赖（BOLD, Blood Oxygen Level Dependent）信号活动，以及视觉皮层与运动皮层间的功能连接，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，以此实现灵活且精准的协调调控。 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- data_figures.xlsx 包含复现论文手稿中所有图表所需的数据：工作表1对应图1，工作表2对应补充图S1，工作表3对应图2，工作表4对应补充图S2，工作表5对应图3，工作表6对应图4，工作表7对应补充图S3。 _______________________________________________________________________________________ residualData_V1M1.mat 包含用于计算感兴趣区（ROIs, Regions of Interest）间相关性的数据。其中"residuals"为1×4元胞数组，存储了每次视觉刺激呈现前后各感兴趣区的残差数据。residual{1}对应70ms延迟条件下的数据，residual{2}对应150ms延迟条件下的数据，residual{3}对应230ms延迟条件下的数据，residual{4}对应310ms延迟条件下的数据。每个元胞均包含3个维度：维度1为试次（trials），维度2为磁共振成像重复时间（TRs, Repetition Time），取值范围为-1至4，维度3为感兴趣区（其中1代表V1脑区，2代表M1脑区）。 _______________________________________________________________________________________ betas_vision_and_action.nii.gz 存储了用于复现图1C的左右脑半球（叠加层1为左侧半球，叠加层2为右侧半球）中“视觉与动作”事件的β图。该β图报告了经错误发现率（FDR, False Discovery Rate）校正后的显著性阈值掩蔽的β值，其中零值代表该顶点的β值不具有统计学显著性（或未被功能磁共振成像（fMRI, functional Magnetic Resonance Imaging）扫描覆盖）。左右脑半球的β图均被投影至镜像对称的fsaverage_sym标准模板空间。 _______________________________________________________________________________________ betas_action_for_decision.nii.gz 存储了用于复现补充图S1D的左右脑半球（叠加层1为左侧半球，叠加层2为右侧半球）中“用于决策的动作”事件的β图。该β图报告了经错误发现率（FDR）校正后的显著性阈值掩蔽的β值，其中零值代表该顶点的β值不具有统计学显著性（或未被fMRI扫描覆盖）。左右脑半球的β图均被投影至镜像对称的fsaverage_sym标准模板空间。 _______________________________________________________________________________________ betas_peak_vs_trough.nii.gz 存储了用于复现补充图S1E的左右脑半球（叠加层1为左侧半球，叠加层2为右侧半球）中峰延迟与谷延迟条件下的β值差异图。该图报告了β值，其中零值代表该顶点的β值不具有统计学显著性（或未被fMRI扫描覆盖）。左右脑半球的图像均被投影至镜像对称的fsaverage_sym标准模板空间。
