Modeling multi-sensory feedback control of zebrafish in a flow

Illustration of the wall calibration process.
(A) Two-dimensional projection of the difference of vortex strengths Γl − Γr, as a function of the projected distance, d, and angle to collision, φ, for one trial from Bright. The black curve is a normal function utilized to select relevant values of (φ, d) associated with those instances when the fish turns according to the angle to collision ϕ. (B) Example of calibration of the wall function. Black dots correspond to Gϕ and green dots correspond to the filtered output of |Gϕ|. The red line is the fitted wall function.
