Document Summary
Brevia imagine playing tennis, significant activity was observed in the supplementary motor area (fig. In contrast, when she was asked to im- agine walking through her home, significant activity was observed in the parahippocampal gyrus, the posterior parietal cortex, and the lateral premotor cortex (fig. Her neural responses were indistinguishable from those observed in healthy volunteers (fig. S2) performing the same imagery tasks in the scanner (som text). Moreover, her decision to cooperate with the authors by imagining partic- ular tasks when asked to do so represents a clear act of intention, which confirmed beyond any doubt that she was consciously aware of herself and her surroundings.
