Fig. 4: Cognitive space and cortical mapping.
From: Quantitative models reveal the organization of diverse cognitive functions in the brain
a The cortical map of the cognitive space shown on the inflated and flattened cortical sheets of subject ID01 (Supplementary Fig. 5 shows all other subjects); PC1–PC3 are shown in red, green, and blue, respectively. b–d Examples of the task selectivity for voxels in the b left middle temporal, c left medial frontal, and d right superior temporal regions, mapped onto the two-dimensional cognitive space based on the loadings of the first and second principal components (PC1 and PC2, respectively) of the model weights. Tasks with positive and negative weight values were denoted in red and blue, respectively. The circle size was modulated based on the absolute weight value. For better visibility, only 24 tasks are shown in white. e The left inferior parietal lobule (IPL) corresponding to the orange square part in the inflated cortical sheet (a). f–h Three voxels along with the inferior to superior direction were selected to show the topographic change of task selectivity. For better visibility, only 18 tasks with positive weight values are shown in white.
