A system for tracking whisker kinematics and whisker shape in three dimensions
Fig 8
Comparison of 2D and 3D curvature as mouse whisks against a pole (whisker C2): curvatures (upper panel)-, 3D kinematics (middle panel) and curvature change (bottom panel, Δκ3D, Δκh, and Δκv). A) Contact episode where both movement and bending of the whisker were largely restricted to the horizontal plane. In this case, Δκ3D and Δκh were highly correlated. Grey shading indicates periods of whisker-pole contact. See S3 Movie. B) Example with same whisker as panel A for contact episode with significant vertical component of whisker motion. See S4 Movie.
