Human forebrain organoids classified artificial tactile Braille signals after a sensor converted the touch data into electrical stimulation. Accuracy averaged 61% with one organoid and rose to 83% when responses from three organoids were combined.
A spiking neural network model of the retina was trained either to represent incoming images or to predict scenes roughly 100 milliseconds into the future. The prediction-focused model reproduced several known retinal responses and matched how retinal output cells from different animal species respond to natural images and movies.
In healthy adults, a subanesthetic dose of nitrous oxide changed how large brain networks were organized during a visual task. Weaker connections involving the insula, a region involved in integrating bodily and emotional signals, were associated with more unpleasant visual experiences.
