Lead or the trailing sister can initiate directional switching.

Abstract

<p>(A) Example trajectory exhibiting lead initiated directional switching (LIDS; magenta dashed lines) and trail initiated directional switching (TIDS; black dashed lines). (B) Probability of the trailing vs. lead sister switching first (n = 2063 switch events). Dotted white line indicates the boundary where <i>p</i>_LIDS = <i>p</i>_TIDS.</p
