In order to further elucidate the hypothesis that the telencephalon of ectothermic vertebrates functions primarily as a non-specific arousal mechanism, facilitating lower brain areas, (the Arousal Hypothesis) the South African clawed frog, Xenoous laevis, was studied in four behavioral situations before and after telencephalon ablation, olfactory bulb ablation or sham surgery. Particular attention was paid to measurements of the temporal aspects of the behaviors studied.
The behaviors studied were:
1. Habituation to an acoustic-vibratory stimulus
2. The optomotor response
3. Escape from shallow water
4. Feeding behavior
In the habituation experiment no changes were found in the number of …
