From: Adaptation of cortical activity to sustained pressure stimulation on the fingertip
Linear decreases in inter-regional functional connectivity during pressure stimulation. The correlation coefficients (y-axis) in the inter-hemispheric (cBA3-iBA40 with p < 0.01 and iBA40-cBA13 with p < 0.001), ipsilateral (iBA40-iBA13 with p < 0.05 and iBA40-iBA5 with p < 0.05), and local cSI (cBA1-cBA2 with p < 0.01) connections significantly decreased during 15 s pressure stimulation. The correlation coefficients in one of the contralateral connections (cBA3-cBA5 with p < 0.05) significantly increased during 15 s pressure stimulation (linear regression analysis between the correlation coefficients and stimulus duration). Other thirty connections showed no significant change over time
