Upgrade and exploration of Bayesian chemotaxis model has been uploaded on BiorXiv. This is a valuable continuation of theory I developed in Benjamin Friedrich group during my post-doc (CFAED, Dresden). The model is applicable to cells in two-dimensional steady gradients which undergo motility noise, such as slime molds Dictyostelium discoideum. In this work, trade-offs for spatial versus temporal comparison during cellular gradient estimation has been elucidated. JulianRode_2023
