Voxel-wise Aβ 进展模式:通过对 Aβ 积累图的分析,发现高积累者全脑存在显著 Aβ 积累,在眶额内侧区、扣带回和楔前叶尤为明显。APOE 基因型和记忆衰退在右侧中央旁小叶周围存在显著交互作用,ε4 携带者伴记忆衰退在中央前后区和左侧额上回 Aβ 积累更多。 Voxel-wise 灰质萎缩模式:高积累者全脑皮质存在显著 GM 萎缩,
Conventional quantitative medical imaging (radiomics) can be extended to computing voxel-wise features and aggregating tumor subregions with similar radiological phenotypes (imaging habitats) to elucidate the distribution of tumor heterogeneity within and among tumors. Despite the promising applications of ...
但是Voxel-Wise现在主要还是Gallant他们组,还有Kendrick Kay自己的组在用。Kendrick Kay在用类似Voxel-Wise的方法在经常做pRF(Population Receptive Field)这些东西。想要研究一些Top-Down,Attention之类的东西(Kay et al. 2016)。 我认为这也是一个很好的思路,可以吧MVPA和VW结合起来。MVPA可以用来评判脑区对特定任务...
关键词是Voxel-Wise模型 。这个模型将外界信号(如声音或者图片)和相对应的大脑反应(也就是BOLD信号)进行「寻找信号中的特征」。譬如,挑西瓜的时候,你会敲敲西瓜看它的声音如何,来判断它是不是个好西瓜。这就是个特征。通过寻找外界信号中的特征,然后拟合为相应的BOLD信号。因为核磁共振扫描图上,是按照一个一个立...
voxel-wise就是基于voxel水平的分析；ROI-wise是基于ROI水平分析。你比如在做功能连接的时候，基于voxel做的话，你选择一个或多个种子点，然后每个种子点的平均时间序列与全脑每个体素的时间序列做相关性分析，做出来就是种子点的全脑功能连接图；基于ROI做的话，你选择多个ROI，然后各个ROI时间序列之间做...
Therefore, this paper presents a voxelwise based multi-frequency band brain functional network model, called Multi-graph brain functional network. First, our analysis found the low-frequency information on the BOLD signal of the brain functional network obscures the other information because of its ...

The voxel-wise encoding models and activity from the perception runs (middle) were used to perform image identification (bottom middle). The same voxel-wise encoding models and activity from the imagery runs (right) were used to perform mental image identification (bottom right). During image ...
The voxel-wise semantic models predict BOLD responses in many brain areas, including SPFC, IPFC, LTC, VTC, LPC and MPC. These same regions have been previously identified as the semantic system in the human brain. Back to article page...
