The sensation of groove has been defined as the pleasurable desire to move to music, suggesting that both motor timing and reward processes are involved in this experience. Although many studies have investigated rhythmic timing and musical reward separately, none have examined whether the associated cortical and subcortical networks are engaged while participants listen to groove-based music. In the current study, musicians and non-musicians listened to and rated experimentally controlled groove-based stimuli while undergoing functional magnetic resonance imaging. Medium complexity rhythms elicited higher ratings of pleasure and wanting to move and were associated with activity in regions linked to beat perception and reward, as well as prefrontal and parietal regions implicated in generating and updating stimuli-based expectations. Activity in basal ganglia regions of interest, including the nucleus accumbens, caudate and putamen, was associated with ratings of pleasure and wanting to move, supporting their important role in the sensation of groove. We propose a model in which different cortico-striatal circuits interact to support the mechanisms underlying groove, including internal generation of the beat, beat-based expectations, and expectation-based affect. These results show that the sensation of groove is supported by motor and reward networks in the brain and, along with our proposed model, suggest that the basal ganglia are crucial nodes in networks that interact to generate this powerful response to music.

凹槽的感觉参与运动和奖励网络

律动的感觉被定义为移动到音乐中的愉悦欲望，这表明运动时间和奖励过程都参与了这种体验。尽管许多研究分别调查了节奏时间和音乐奖励，但没有一项研究在参与者听基于律动的音乐时相关的皮层和皮层下网络是否参与。在当前的研究中，音乐家和非音乐家在进行功能性磁共振成像时聆听并评价实验控制的基于凹槽的刺激。中等复杂性节律引起更高的愉悦感和想要移动的评分，并且与与节拍感知和奖励相关的区域以及涉及产生和更新基于刺激的期望的前额叶和顶叶区域的活动相关。感兴趣的基底神经节区域的活动，包括伏隔核、尾状核和壳核，与快乐和想要移动的等级有关，支持它们在凹槽感觉中的重要作用。我们提出了一个模型，其中不同的皮质-纹状体回路相互作用以支持凹槽的机制，包括节拍的内部生成、基于节拍的期望和基于期望的影响。这些结果表明，凹槽的感觉是由大脑中的运动和奖励网络支持的，并且与我们提出的模型一起表明，基底神经节是网络中的关键节点，它们相互作用以产生对音乐的这种强大反应。支持它们在凹槽感觉中的重要作用。我们提出了一个模型，其中不同的皮质-纹状体回路相互作用以支持凹槽的机制，包括节拍的内部生成、基于节拍的期望和基于期望的影响。这些结果表明，凹槽的感觉是由大脑中的运动和奖励网络支持的，并且与我们提出的模型一起表明，基底神经节是网络中的关键节点，它们相互作用以产生对音乐的这种强大反应。支持它们在凹槽感觉中的重要作用。我们提出了一个模型，其中不同的皮质-纹状体回路相互作用以支持凹槽的机制，包括节拍的内部生成、基于节拍的期望和基于期望的影响。这些结果表明，凹槽的感觉是由大脑中的运动和奖励网络支持的，并且与我们提出的模型一起表明，基底神经节是网络中的关键节点，它们相互作用以产生对音乐的这种强大反应。
