Stroke-induced changes in functional connectivity reverse germ-free effects

(A) Whole-brain matrices of Pearson correlation values and standard deviation for all 98 × 98 connections in the SPF and GF group, respectively.

(B) Distribution of degree and node strength (Poisson regression with likelihood ratio test: different curve for each dataset, p < 0.001).

(C) Difference in total degree or node strength between SPF and GF (Student's t test, p < 0.05 for degree; p < 0.01 for node strength).

Data are represented as split adjacency matrix (average Pearson correlation coefficient across animals per connection and related SD), histogram (counts of mean degree or mean strength values), and individual data points. SPF n = 8, GF n = 15
