Model of OKR feedback loop in bel larvae with different amounts of misprojection. A, In the absence of misprojecting fibers, the clockwise rotating visual stimulus (black and white) is perceived by the stimulated eye (gray) and the information is transferred across the midline (dashed line) to the yet unknown contralaterally located OIN. The OIN sends the signal again across the midline to the motor nuclei (MN) of the stimulated eye, leading to a compensatory eye movement in the direction of the stimulus (gray arrow around the eye). The other eye is driven in the same direction (dashed arrow). B–E, With an increasing amount of misprojection, more signal is sent to the ipsilateral OIN, leading to transmission of the information to the wrong eye (see Discussion). The size of the arrows represents the amount of information flow in each direction.
