Parametric analysis of rate dependent effects during fingertapping

		Patient group		Control group
		Main effect (all frequencies)	First order term (positive linear)	Main effect (all frequencies)	First order term (positive linear)
Pre‐SMA	Left	6.75/7.74 [−3 9 48] 285 voxels *	5.73/8.57 [−3 15 48] 251 voxels *	6.26/9.38 [0 9 51] 339 voxels *	6.01/9.26 [−3 12 51] 248 voxels *
SMA proper	Mesial	5.84/6.86 [3 0 54] 285 voxels *	6.72/7.34 [−3 −3 63] 251 voxels *	5.79/8.63 [3 6 57] 339 voxels *	5.34/9.42 [3 0 57] 248 voxels *
Premotor cortex	Right	4.97/4.65 [39 −3 57] 94 voxels	4.76/8.80 [42 −6 57] 78 voxels	6.02/5.09 [42 −3 54] 72 voxels	n.s.
SMC	Left	6.43/8.59 [−33 −30 54] 351 voxels	5.92/10.02 [−33 −33 57] 389 voxels	7.33/13.47 [−42 −30 51] 401 voxels	6.38/14.46 [−33 −30 57] 343 voxels
	Right	5.81/7.08 [48 −30 54] 157 voxels	5.17/5.92 [24 −42 57] 122 voxels	4.93/7.01 [45 −42 54] 104 voxels	n.s.

Z scores (cursive) and T values represent activation maximum within each region. The extent of each activated area is given by the numbers of activated voxels. SPM‐coordinates are printed in square brackets. Parametric analyses concerning the “First order term” (negative linear, e.g. decreasing activation in parallel with increasing frequency of movement) and positive as well as negative “Second order term” (quadratic effect) revealed no significant results in the patient or control group.

^*Due to an overlap between pre‐SMA and SMA proper the number of activated voxels are given for both regions together.
