Knots: Attractive Places with High Path Tortuosity in Mouse Open Field Exploration
Figure 4
An illustration of the operation of the algorithm for mapping the boundaries of knots.
A. A selected mouse-session cumulative path plot. B. A contour plot of fine-grained curvature topography of the same session. C. High curvature patches are circumscribed by a black boundary. D. The boundaries of u-turns are drawn in black. These patches of u-turns are filtered out. The boundary of the knot is singled out and drawn in red. In both B and C the colors represent path curvature measured with a 20cm window. Curvature values are represented by the same colors as in Figure 3.
