Lateral Stimuli Behavior in Post-Lesion Frogs

Frog 1- Right Tectal Lobe Ablation

For lateral stimuli pre-lesion frogs show the same intrinsic variability as seen in the frontal data, but displacements are equally distributed over the prey line, instead of the mid-sagittal plane. The prey line provides a better characterization of frog behavior for lateral stimuli than the mid-sagittal plane, because it is not fixed line of reference.

Post-lesion frogs exhibit the same bias to displace to the ipsilateral side of the prey-line, as was observed in the frontal trials, where the prey line and mid-sagittal plane were aligned.
