正电子发射断层扫描研究人类舞蹈，以确定其系统级组织。舞蹈的三个核心方面进行了检查：夹带，米和模式化的运动。业余舞者在没有视觉指导的情况下，随着探戈音乐的节拍，在倾斜的表面上进行小规模的循环重复探戈舞步。与自我调节的运动相比，伴随音乐的舞步是由小脑前蚓部支持的。运动到一个规则的，公制节奏，相比运动到一个不规则的节奏，暗示右壳核在公制运动的自愿控制。空间导航的腿部运动在舞蹈中，当控制肌肉收缩，激活内侧上级顶叶小叶，反映本体感觉和体感的贡献，空间认知舞蹈。最后，额外的皮质，皮质下和小脑区域活跃在系统水平。与最近关于简单的、有节奏的、运动感觉行为的研究一致，这些数据揭示了在舞蹈中整合的空间模式化的、双足的、有节奏的运动过程中活跃的大脑区域的相互作用网络。
Human dance was investigated with positron emission tomography to identify its systems-level organization. Three core aspects of dance were examined: entrainment, meter and patterned movement. Amateur dancers performed small-scale, cyclically repeated tango steps on an inclined surface to the beat of tango music, without visual guidance. Entrainment of dance steps to music, compared to self-pacing of movement, was supported by anterior cerebellar vermis. Movement to a regular, metric rhythm, compared to movement to an irregular rhythm, implicated the right putamen in the voluntary control of metric motion. Spatial navigation of leg movement during dance, when controlling for muscle contraction, activated the medial superior parietal lobule, reflecting proprioceptive and somatosensory contributions to spatial cognition in dance. Finally, additional cortical, subcortical and cerebellar regions were active at the systems level. Consistent with recent work on simpler, rhythmic, motor-sensory behaviors, these data reveal the interacting network of brain areas active during spatially patterned, bipedal, rhythmic movements that are integrated in dance.
