Decoding dynamic visual scenes across the brain hierarchy
Fig 3
Decoding results in each brain region.
(A) Samples of original images (Origin) and decoded images in each combined brain region (Visual cortex, nucleus, hippocampus). The decoded results in shuffled spikes across all brain regions listed as a baseline. (B) Corresponding decoding metrics in each case of (A). SSIM and PSNR metrics in each brain region and baseline with shuffled data. (C) Decoding matrices where the diagonal elements are the values in (B) and the off-diagonal elements are the values of model generalizability, e.g., using the models trained on each brain area to predict other test brain areas. Marked values are the means of over 400 test images in this the following figures. Images are natural movies presented as visual stimuli in the Allen Visual Coding—Neuropixels dataset (https://portal.brain-map.org/circuits-behavior/visual-coding-neuropixels).
