Human ECoG speaking consonant-vowel syllables

The enclosed data is collected using a high-density 256-channel electrocorticography (ECoG) array implanted in human patients during treatment for epilepsy. The subjects are reading aloud consonant-vowel syllables from a list. The data was collected by Dr. Edward Chang and Dr. Kristofer Bouchard at the University of California, San Francisco, and curated by Dr. Kristofer Bouchard and Dr. Benjamin Dichter. Data is organized by subject ID, and each file is a continuous recording session in Neurodata Without Borders (NWB) 2.0 format. Voltage traces are included for each of the recorded 256 channels. Microphone signal was recorded at the time but is removed for HIPAA compliance. Detailed hand-marked annotations are provided which mark what syllable was said, and the times of the start, consonant-vowel transition, and end of each syllable. A rest-period time is also included when the subject was silent, which can be used as a baseline. Hand-marked anatomical labels are included for electrodes in the relevant brain regions. All dates have been removed for HIPAA compliance and replaced with Jan 1, 1900.

本附属数据集采用高密度256通道皮层脑电图（electrocorticography, ECoG）阵列采集，该阵列植入于癫痫治疗过程中的人类患者体内。受试者需朗读预设列表中的辅音-元音音节。数据集由加州大学旧金山分校的Edward Chang博士与Kristofer Bouchard博士采集，并由Kristofer Bouchard博士与Benjamin Dichter博士完成整理标注。数据集按受试者ID进行组织，每个文件均为采用无国界神经数据（Neurodata Without Borders, NWB）2.0格式存储的连续录制会话文件。所有256个记录通道均包含对应通道的电压轨迹数据。麦克风信号虽在采集时同步录制，但为符合《健康保险流通与责任法案》（Health Insurance Portability and Accountability Act, HIPAA）的隐私合规要求已被移除。数据集附带详细的人工标注信息，可标记每个音节的内容、起始时刻、辅音-元音转换时刻及结束时刻。此外还包含受试者静默状态下的休息时段数据，可作为实验基准参照。相关脑区电极附带人工标注的解剖学标签。为符合HIPAA隐私合规要求，所有真实日期均已被移除，统一替换为1900年1月1日。
