Masked autoencoders learn perception-relevant neural representations from unlabeled data

Researchers have demonstrated that masked autoencoders can learn meaningful representations from unlabeled neural data, specifically resting-state neural activity. By pretraining a masked autoencoder on hours of spontaneous multiunit activity from the V1 region of a blind participant's brain, the model successfully captured interpretable structures related to the brain's spatial organization and perceptual state separation. This unsupervised pretraining strategy proved effective for improving neural decoding, achieving 84.1% accuracy on a general psychometric task and 64.0% on a more challenging threshold-level task using linear probing on the model's frozen latent representations.
