Unlocking the Secrets of the Brain: NeuroImageGen Generates Images from EEG Signals

The Fascinating World of Brain Imaging and Reconstruction

The human brain is a fascinating organ that holds the key to understanding life itself. It controls our thoughts, senses, actions, and so much more. The quest to understand how the brain works has led to groundbreaking research in the field of brain imaging and reconstruction.

Decoding the Brain with EEG and fMRI

Scientists are using advanced tools like functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to record brain activity in response to visual stimuli. This research aims to decode and reconstruct the actual content that triggers these responses in the brain. However, fMRI data collection is expensive and impractical for everyday use, and EEG signals are complex and prone to noise.

Introducing NeuroImageGen

NeuroImageGen is a pipeline for neural image generation using EEG signals. It addresses the challenges associated with EEG-based image reconstruction by incorporating a multi-level semantics extraction module. This module decodes different levels of semantic information from EEG signals, ranging from pixel-level details to sample-level semantics. By leveraging the power of diffusion models, NeuroImageGen can generate high-quality visual stimuli from noisy EEG data.

The integration of multi-level semantics into a latent diffusion model allows for flexible control of the generation process at various semantic levels. This results in reconstructed visual stimuli that combine fine-grained and coarse-grained information to produce high-quality images.

Promising Results

NeuroImageGen outperforms traditional image reconstruction methods on EEG data, enhancing the structural similarity and semantic accuracy of the reconstructed images. This research contributes to our understanding of how visual stimuli impact the human brain.
