Images reconstructed from brain activity

WitrynaAbstract. Understanding how the brain encodes external stimuli and how these stimuli can be decoded from the measured brain activities are long-standing and challenging questions in neuroscience. In this paper, we focus on reconstructing the complex image stimuli from fMRI (functional magnetic resonance imaging) signals. Witryna28 kwi 2024 · A few studies reconstructed visual images from brain activities in the visual cortex by dividing each image into many patches and constructing local decoding model for the patches. Miyawaki et al. reconstructed 10 × 10 binary images from fMRI activity using a combination of local sparse logistic regression (SLR) decoders.
