Table 4 Regional node analyses of the functional brain network revealed by NBS

From: Expertise-related functional brain network efficiency in healthy older adults

Node Weighted node degree p value r
L/R BA Brain region Multi-domain Visuomotor
M (SD) Mdn M (SD) Mdn
L 17b Lingual gyrus, occipital 32.00 (5.74) 31.69 26.74 (5.54) 27.22 .022 0.42
L 17a Lingual gyrus, occipital 29.06 (10.36) 27.61 21.11 (8.66) 20.20 .032 0.40
R 7 Precuneus 17.39 (8.03) 17.77 11.66 (4.13) 10.36 .015 0.45
R 5 Paracentral lobule 16.21 (8.66) 16.73 9.29 (4.00) 8.37 .015 0.45
  1. Nodes of the network in the theta band that differ in weighted node degree between the multi-domain group and the visuomotor group are displayed
  2. L, left hemisphere; R, right hemisphere; BA, Brodmann area derived from sLORETA; M, mean; SD, standard deviation; r, effect size. The weighted node degree was compared between groups with the Mann–Whitney U test. Exact p values are reported uncorrected
