Absolute pitch (AP) can identify and designate the pitch chroma of a particular tone without using any external references. Unknown neurological mechanisms underlie it. We report the case of a 53-year-old AP musician who developed a right parietal hemorrhage but conserved AP ability. Our case had a lesion in the right parietal lobe that did not affect her AP ability. Our case further supports the hypothesis that the left cerebral hemisphere is important for AP ability.
绝对音高（AP）能够在不借助任何外部参照的情况下识别并指明特定音调的音级。其背后的神经机制尚不明确。我们报告了一例53岁的具有绝对音高能力的音乐家，她发生了右侧顶叶出血，但绝对音高能力得以保留。我们的病例右侧顶叶有损伤，但并未影响其绝对音高能力。我们的病例进一步支持了左脑半球对绝对音高能力很重要这一假说。
