Article Title: A shifting role of thalamocortical connectivity in the emergence of cortical functional organization.
Article Snippet: The cortical patterning principle has been a long-standing question in neuroscience, yet how this translates to macroscale functional specialization in the human brain remains largely unknown.. Here we examine age-dependent differences in resting-state thalamocortical connectivity to investigate its role in the emergence of large-scale functional networks during early life, using a primarily cross-sectional but also longitudinal approach.. We show that thalamocortical connectivity during infancy reflects an early differentiation of sensorimotor networks and genetically influenced axonal projection.

Article Snippet: The Silhouette score (SS) was calculated using the mean intracluster (i) and near-cluster distance (n) for each sample; the Silhouette score for a sample is defined by SS 1⁄4 n i max i; nð Þ : (6) Silhouette scores were calculated for original and low rank matrices using the silhouette function in MATLAB to create plots that visualize differences in cluster quality.

Article Snippet: To evaluate the explanatory power of the cluster results, we calculated the percent variance (R2) with the following function: R2 = 1 − ∑ ( X − X̂ )2 ∑ ( Xi − X )2 (2) We calculated the silhouette index (SI) to evaluate the clustering goodness of fit using the silhouette function in Matlab.

The distance between eating clusters across assays is smaller than the distance between approach clusters, indicating the representation of eating is more conserved than food approach (approach sample n = 527 time points, eat sample n = 1958 time points; two-tailed Wilcoxon rank-sum test, z-score = 22.88, p < 0.001). j Same as d , but for co-registered cells, showing conserved representation of behaviors across assays ( n = 4 mice; one-one-sample two-tailed t -test, t-statistic = 4.22, p = 0.024). k The distance between individual points and cluster center is smaller in the eating cluster than the approach cluster, indicating the representation of eating is more conserved across assays (approach sample n = 1049 time points, eat sample n = 5492 time points; two-tailed Wilcoxon rank-sum two-tailed test, z-score = 10.35, p < 0.001). *** p < 0.001, ** p < 0.01, * p < 0.05, † p = 0.059.
