Moving Relative to the Past: Reliance on Derivative and Absolute Proprioceptive Feedback for Bayesian State Estimation
Public defence of PhD thesis by Erik Skjoldan Mortensen.
During everyday life, the brain continually attempts to estimate the pose of the body, the positions of the limbs, and how they are moving. This process is termed state estimation and is essential for the skilled motor control we are capable of. Central to this process is the sense of proprioception, which comprises feedback from sensors situated in our skin, joints and muscles.
In this thesis, I have investigated a particular feature of this process: namely, the extent to which velocity-based proprioceptive feedback contributes directly to the estimation of positional parameters, e.g., the extent to which your perception of hand position depends on sensory signals that indicate the speed at which it is moving. Such a function is well-supported in predictive frameworks of sensorimotor control, but has, so far, been minimally investigated.
