BINOCULAR COUPLING IN CHAMELEON SACCADE GENERATION

Chameleons are capable of making a saccade with one eye while the othe r does not move. This virtually unique feature poses questions regardi ng the organization of the saccadic system of the chameleon. By compar ing real data with a simulated test signal, we studied whether the sac cade generation of the left and right eye can be considered as truly i ndependent. This appeared not to be the case, since there was an incre ased likelihood to start saccades in close temporal proximity in the t wo eyes. However, the coupling does not reflect a common saccadic moto r signal for both eyes, since even saccades that were made in close te mporal proximity did not have correlated metrics.
