Figure S5. Illustration of the method for isolating 90-degrees and 180-degrees turns in a single selected ascent, in order to count direction changes. A) The original path traced on the wall during ascent 182 of mouse V07. The directionality of the movement within the ascent is marked by a transition from yellow (ascent starts) to red (ascent ends). B) The movement is constrained to either only vertical or only horizontal, by reducing the lower respective speed to zero and reconstructing the path. C) Noise reduction by repeated moving average (two repetitions with window width of 1.6 seconds). D) Repetition of the step presented in panel B using the smoothed coordinates. The estimate for the number of direction changes is the number of 90-degrees and 180-degrees turns in the path presented in panel D (in this example 34).
