Researchers have developed a novel method for learning universal representations from electroencephalogram (EEG) signals using microstates, which are discrete building blocks of brain activity. This approach, detailed in a new paper, involves clustering continuous EEG data into sequences of these microstates to create a universal tokenizer. This tokenizer has demonstrated superior performance across various downstream tasks, including sleep staging, emotion recognition, and motor imagery classification, compared to traditional time- and frequency-domain feature extraction methods.
