Figure 5. A–D, Plots of individual digit and group averaged OIS signal amplitudes (A, B) and areas of activation (C, D) in areas 3b and area 1 in normal and lesioned conditions. A, B, The total number of digits for amplitude measure is n = 25 in normal area 3b (A: D1, n = 6; D2, n = 6; D3, n = 6; D4, n = 4; D5, n = 3), and n =19 in normal area 1 (B: D1, n = 3; D2, n = 5; D3, n = 3; D4, n = 4; D5, n = 4), respectively. The total number of digits for amplitude measure is n = 7 in lesioned area 3b (A: D1, n = 2; D2, n = 3; D3, n = 1; D4, n = 1), and n = 6 in lesioned area 1 (B: D1, n = 1; D2, n = 2; D3, n = 1; D4, n = 2), respectively. C, D, The total number of digit pairs (prelesion vs postlesion) for area measure is n = 6 in area 3b (C: D1, n = 2; D2, n = 3; D3, n = 1), and n = 3 in area 1 (D: D1, n = 1; D2, n = 1; D4, n = 1). One-way ANOVA test was performed to examine the amplitude differences across digits in normal area 3b (A) and area 1 (B). N.S.p > 0.05, *p < 0.05. Error bars indicate the SE. An unpaired t test was performed to compare the amplitude differences between total normal and lesioned digits (total columns in A and B). Paired t test was performed to examine the activation area difference between prelesion and postlesion conditions (total columns in C and D). *p < 0.05. Error bars indicate the SE.
