Changing cognitive chimera states in human brain networks with age: Variations in cognitive integration and segregation
Fig 5
The classification proportions across cross-sectional age over five select cognitive systems: a) auditory-left (Aud-L; dark blue), b) auditory-right (Aud-R; dark purple), c) ventral temporal (magenta), d) default mode (pink), and e) attention (orange).
Blue circles represent the asynchronous classification proportions, yellow squares represent the chimera state classification proportions, and red triangles represent the synchronous classification proportions. The first column shows the brain region labels that belong to the respective cognitive system for each cognitive system, the second column shows where the brain regions are located spatially, and the third column shows how the classification proportions change with cross-sectional age. Shaded regions are 95% confidence intervals (CI) across individuals. Here and throughout, these are calculated as , where
is the mean of the classification proportion for an age group, t is the critical t-value corresponding to 95% confidence intervals, σ is the standard deviation of the classification proportion for an age group, and n is the number of individuals for an age group. The maps of brain regions were drawn using the open-sourced ‘ggseg‘ package in R [77].
