This paper describes a method for converting sleep Electroencephalogram (EEG) signals into music. For that purpose, a new segmentation procedure is used for extracting relevant information from the sleep EEG that is then translated into sequences of notes, chords, arpeggios and pauses, with a varying tempo that is defined by sleep stages. The final outcome is a direct time-domain conversion of the brain activity during sleep into sound. Since typical sleep EEGs vary with age and sleep disorders, different groups of subjects were used in the experiments: babies, sane adults and patients with air-flow limitation.

Brain's Night Symphony (BraiNSy)：脑电图超声处理方法

本文介绍了一种将睡眠脑电图 (EEG) 信号转换为音乐的方法。为此，使用新的分段程序从睡眠 EEG 中提取相关信息，然后将其转换为音符、和弦、琶音和停顿序列，并具有由睡眠阶段定义的不同节奏。最终结果是将睡眠期间的大脑活动直接时域转换为声音。由于典型的睡眠脑电图随年龄和睡眠障碍而变化，因此实验中使用了不同的受试者组：婴儿、正常的成年人和气流受限的患者。
