Neural Evidence for Visual Simulation of Object Movement in the Human Visual Cortex

The ability to visually simulating sensory, motor, and cognitive representations and imagine potential future actions is crucial for our daily life. However, the neural basis underlying the visual simulation of object movement remains partially understood. Past work using human fMRI decoding has provided some evidence for the reactivation of motion-responsive areas of the visual cortex during mental simulation. Here, we tested a human patient with implanted stereoelectroencephalography (sEEG) electrodes while they played the 'Planko' game, where they were asked to predict the trajectory of a ball falling through a field of planks. The patient learned to play the game significantly above chance 68.9%. We use time-frequency analysis to study the similarity between the beta event of mental simulation and video watching. We also used the deep learning method to find a joint embedding between observed and simulated events.
