Fig. 9.2 a
Modulation index time course of the type-I lPAC activity.
b
Voxels containing statistically
significant lPAC activity having the type I time course.
c
Modulation index time course of the
type II lPAC activity.
d
Voxels containing statistically significant lPAC activity having the type II
time course.
e
Modulation index time course of the type III lPAC activity.
f
Voxels containing
statistically significant lPAC activity having the type III time course. The significant activities in
