Comprehensive Review of EEG-to-Output Research: Decoding Neural Signals into Images, Videos, and Audio
This review synthesizes existing work for researchers in neuroscience and AI, but it is incremental as it does not introduce new methods or results.
This paper systematically reviews EEG-to-output research, analyzing 1800 studies to identify trends, challenges, and opportunities in decoding neural signals into images, videos, and audio, emphasizing the potential of advanced generative models and the need for standardized datasets.
Electroencephalography (EEG) is an invaluable tool in neuroscience, offering insights into brain activity with high temporal resolution. Recent advancements in machine learning and generative modeling have catalyzed the application of EEG in reconstructing perceptual experiences, including images, videos, and audio. This paper systematically reviews EEG-to-output research, focusing on state-of-the-art generative methods, evaluation metrics, and data challenges. Using PRISMA guidelines, we analyze 1800 studies and identify key trends, challenges, and opportunities in the field. The findings emphasize the potential of advanced models such as Generative Adversarial Networks (GANs), Variational Autoencoders (VAEs), and Transformers, while highlighting the pressing need for standardized datasets and cross-subject generalization. A roadmap for future research is proposed that aims to improve decoding accuracy and broadening real-world applications.
