From: Adaptation of cortical activity to sustained pressure stimulation on the fingertip
Exponential decreases in cortical activation during pressure stimulation. The number of suprathreshold voxels (y-axis) in cBA3 (p < 0.05, τ = 5.69 s), cBA1 (p < 0.01, τ = 18.03 s), cBA2 (p < 0.05, τ = 5.66 s), and cBA40 (p < 0.05, τ = 20.99 s) significantly decreased during 15 s pressure stimulation (generalized linear model analysis with a log-linear function). However, no significant change was shown in iBA40 and cBA13. iBA13, cBA5, and iBA5 also had no significant change (not shown here)
