voxel‐wise encoding modelPerceiving disparities is the intuitive basis for our understanding of the physical world. Although many electrophysiology studies have revealed the disparity‐tuning characteristics of
Fig. 2. Voxel-wise encoding model performance and voxel-binning procedure. A) Histogram of voxel-wise encoding model prediction accuracy for all voxels in the functional volume acquired for Subject 1. For each voxel the model prediction accuracy is the correlation between the encoding model predicti...
Voxel-Wise Model 有什么用? MVPA现在已经逐渐变成一种神经科学领域常用的分析手段(Norman et al. 2006),用来衡量某个脑区对特定任务的表征精度,最近北大方方老师非常前瞻性的一个大脑功能分区动态表征的文章就用到了这个方法(Chen et al. 2016)。但是Voxel-Wise现在主要还是Gallant他们组,还有Kendrick Kay自己的组...
2、这种方法其实就是将心理成分量化,然后参与GLM之后的二次重新建模分析,本质上还是Friston他们开辟的GLM方法,最新的论文你可以看看有一篇万小红发表在nature上的Neural encoding of opposing strategy values in anteriorand posterior cingulate cortex,当时看了之后,感觉精彩到尿了,如此高级的心理过程,也给量化并且脑...
Voxelwise encoding models based on convolutional neural networks (CNNs) have emerged as state-of-the-art predictive models of brain activity evoked by natural movies. Despite their superior predictive performance, the huge number of parameters in CNN-based models have made them d...
Using a voxel-wise encoding model trained on these features, we found that models based on visual (motion energy) and social (faces, social interaction, ToM, valence, and arousal) features can both predict brain activity in children as young as 3years old across the cortex, with particularly...
Using a voxel-wise encoding model trained using these features, we find that visual (motion energy) and social (faces, social interaction, ToM, valence, and arousal) features can both predict brain activity in children as young as three years old across the cortex, with particularly high ...
We ?t voxelwise encoding models to estimate tuning for scene categories that re?ect statistical ensembles of objects and actions in the natural world. Voxelwise modeling (VM) is a powerful framework to predict single voxel responses evoked by a rich set of stimulus features present in complex ...
Due to the variety of neuron morphology and the lack of large neuron datasets, most of current neuron segmentation models rely on introducing complex and specially-designed submodules to a base architecture with the aim of encoding better feature representations. Though successful, extra burden would...
Voxel-wiseanalysisVascular disorders can either be cause or consequence in the pathophysiology of Alzheimer's disease (AD). To comprehensively characterize the occurrence of vascular impairment in a double transgenic mouse model for AD (APPswe/PS1dE9) during aging, we developed a new method to ...
