Neural mechanisms of optic flow processing for visually-guided control of steering
When an observer moves through the environment, self-motion creates large-field patterns of visual motion known as optic flow. Cortical processing of optic flow is important for perception of self-motion, as demonstrated in animal models. In most navigation behaviors, such as driving a vehicle, optic-flow processing is part of an active sensing loop in which self-motion produces optic flow which is, in turn, used to change direction at the next instant of time. While this is a natural mode of optic flow processing, almost all previous studies of neural processing of optic flow involve passive self-motion without an active control component. Indeed, the patterns of optic flow that are…
