Chapter 4: Head rotation sensation is a splendid example of dynamic #Bayesian multisensory fusion since it involves several sensors with different dynamics. These sensor can be put in conflict or switched on/ off experimentally. Follow the tour! #vestibular 
2/ We have (at least) 3 rotations sensors with different dynamics: the inner ear's canals detect acceleration; vision velocity, and graviceptors position (when rotating in vertical planes). The brain also relies on a zero velocity prior. Looks like a job for a #Kalmanfilter!
3/ I will explain (&simulate) motion perception during constant velocity rotations (starting from 0 velocity at t=0). Each sensor can report the motion, or 0, or be off altogether. There's experiments in the literature covering nearly all combinations! This will be a long thread!
