MindBigData

The version 1.0 of the open database contains 1,151,268 brain signals of 2 seconds each, captured with the stimulus of seeing a digit (from 0 to 9) and thinking about it, over the course of almost 2 years between 2014 & 2015, from a single Test Subject David Vivancos. All the signals have been captured using commercial EEGs (not medical grade), NeuroSky MindWave, Emotiv EPOC, Interaxon Muse & Emotiv Insight, covering a total of 19 Brain (10/20) locations. In 2014 started capturing brain signals and released the first versions of the "MNIST" of brain digits, and in 2018 released another open dataset with a subset of the "IMAGENET" of The Brain. Version 0.05 (last update 09/28/2021) of the open database contains 24,000 brain signals of 2 seconds each, captured with the stimulus of seeing a real MNIST digit (from 0 to 9) 6,000 so far and thinking about it, + the same amout of signals with another 2 seconds of seeing a black screen, shown in between the digits, from a single Test Subject David Vivancos in a controlled still experiment to reduce noise from EMG & avoiding blinks.

该开放数据库的1.0版本包含由单一受试者David Vivancos在2014年至2015年期间，经过近两年的研究采集的11,151,268个时长为2秒的脑电信号。这些信号在受试者观看数字（从0到9）并思考该数字的刺激下产生。所有信号均采用商业级脑电图（非医疗级）进行采集，包括NeuroSky MindWave、Emotiv EPOC、Interaxon Muse及Emotiv Insight等设备，覆盖了10/20个脑部位置。自2014年起开始采集脑电信号，并发布了首个“脑部MNIST”版本。至2018年，发布了另一个包含“脑部IMAGENET”子集的开放数据集。开放数据库的0.05版本（最后更新日期为2021年9月28日）包含24,000个时长为2秒的脑电信号，这些信号在受试者观看真实的MNIST数字（从0到9）并思考的刺激下产生，至今已采集6,000个此类信号，并在数字之间显示相同数量的信号，这些信号对应于受试者观看黑色屏幕的额外2秒，旨在通过控制静态实验减少肌电图（EMG）的噪声并避免眨眼。
