Internal models correspond to neural representations of predictions and prediction errors of behaviorally meaningful variables, such as incoming sensory stimuli and motor actions. In a typical experiment to probe internal models, an animal learns to predict the presence of a specific stimulus based on a specific motor action. Such experiments can explain, for example, why when we walk on dry leaves we &#8220;stop hearing&#8221; the predictable sound of leaves crumbling\u2014&#8221;hiding&#8221; from our own action. Existing models of predictive processing do not generalize to more natural scenarios where many stimulus features are predicted (crumbling leaves, a creaking wood floor, etc.). My talk will describe our work on potential biological mechanisms of high-dimensional predictive processing. I will conclude with remarks on ongoing work attempting to use our model to understand neural control of cephalopod camouflage behavior\u2014hiding from others\u2014by recasting this behavior as a high-dimensional prediction.
