本文综述了音乐表演和学习的神经解剖学和神经生理学基础。音乐表演被认为是一种复杂的自愿感觉运动行为，在大量的听觉反馈练习中变得自动化。它涉及大脑的所有运动、躯体感觉和听觉区域。由于神经元连接的终身可塑性，练习乐器首先会导致用于各种组成任务的神经组织数量暂时增加，然后稳定增加。与一般人群相比，10岁以下的音乐家与音乐表演的特定子任务相对应的运动和躯体感觉脑区更大。在极少数情况下，过度使用运动模式可能会导致运动记忆的退化，导致对运动的自主控制丧失，称为音乐家痉挛。具体的治疗选择这种情况下进行审查。
This article reviews the neuroanatomic and neurophysiologic foundations of music performance and learning. Music performance is regarded as complex voluntary sensorimotor behavior that becomes automated during extensive practice with auditory feedback. It involves all motor, somatosensory, and auditory areas of the brain. Because of the lifelong plasticity of neuronal connections, practicing a musical instrument results first in a temporary and later in a stable increase in the amount of nerve tissue devoted to various component tasks. Motor and somatosensory brain regions corresponding to specific subtasks of music performance are larger in musicians starting younger than age 10 years than in the general population. In rare cases, overuse of movement patterns may induce a degradation of motor memory that results in a loss of voluntary control of movements, called musician's cramp. Specific therapeutic options for this condition are reviewed.
