 Abstract: By means of ultrahigh field 9.4T magnetic resonance imag-ing (MRI), we conducted whole-brain functional MRI inhealthy volunteers during performance of a two-alterna-tive forced choice task with upright and inverted biologicalmotion (BM). Neither with upright nor inverted orienta-tions single components of point-light BM trigger bodyrecognition. We revealed differences in the brain circuitsunderpinning upright and inverted BM processing, whichmay be summarized in terms of hemispheric laterality andanteroposterior brain axis: inverted BM activates left ante-rior networks engaged in decision-making, whereas readilyrecognizable upright BM activates solely right posteriorareas. In addition, we implemented several strategies foruncovering ensembles of regions playing in unison such astemporal contrasts analysis and independent componentanalysis. For the first time, we uncovered distributedensembles of regions playing in unison. The outcome pro-vides novel insights on the networks underlying BM proc-essing as an essential part of the social brain.
