Active sensing and flexible neural coding during visually guided navigationSave as calendar entry
Natural behavior is flexible and supported by abstracted away beliefs. To understand dynamic neural processing underlying natural behaviour, we use continuous-time foraging tasks either in virtual reality or in a freely-moving arena. Although task rules do not require any particular eye movement, we find that where subjects look is an important component of the behavior. For example, during a simple task in which macaques use a joystick to steer and catch flashing fireflies in a virtual environment lacking position cues, we find that subjects physically tracked this latent task variable with their gaze – an instance of embodied cognition. Restraining eye movements worsened task performance suggesting that embodiment plays a computational role. The above findings are well explained by a neural model with tuned bidirectional connections between oculomotor circuits and circuits that integrate sensory input. In contrast to other task optimized models, this model correctly predicted that leading principal components of the monkey posterior parietal cortex activity should encode their position relative to the goal. These results explain the computational significance of motor signals in evidence-integrating circuits and suggest that plasticity between those circuits might enable efficient learning of complex tasks via embodied cognition.
