The results of the PLS analysis for the β-band power that characterizes the contrast between the different beat types in the march condition. The results of the PLS analysis for the β-band power that characterizes the contrast between the different beat types in the march condition. The LV1 represents the contrast between the downbeat and upbeat (left, top), which was significant in both march perception and march imagery conditions. The corresponding brain areas in the march perception condition (right, top) demonstrate only the cool colored voxels, in which the β power is decreased for the downbeat compared to the upbeat. In the march imagery condition (bottom), the associated brain areas (right) show both cool colored area (downbeat β decrease > upbeat β decrease) and warm colored areas (e.g., downbeat β decrease < upbeat β decrease). The list of the locations and Talairach coordinates are indicated in Table 1. Ins, Insula; MFG, middle frontal gyrus; MTG, middle temporal gyrus; pHppG, parahippocampal gyrus; PostCG, postcentral gyrus; PreCG, precentral gyrus; PreCu, precuneus; TTG, transverse temporal gyrus.
