Title:
Precision control for a flexible visuo-proprioceptive body representation
Precision control for a flexible visuo-proprioceptive body representation
Abstract:
When controlling action — e.g., hand movements — the brain typically relies on seen and felt posture information to represent 'its' body. Wihtin Bayesian frameworks, it is thought that the brain combines these estimates into a multisensory (e.g. hand) representation in a probabilistic fashion, accounting for how reliable each estimate is in the given context. This puts the top-down control over sensory precision at the centre of multisensory integration. I will present behavioural, brain imaging, and computational modelling work, which jointly suggest that during action, the precision assigned to visual vs proprioceptive information about body position can be changed; e.g., through adoption of an 'attentional set'. I will conclude that (to some degree) body representations can be deliberately shaped by this mechanism; and I will discuss what this implies for the near future — in which entertaining and switching between multiple body representations, e.g. in virtual realities, may be increasingly common.
