| Research Abstract |
We studied structure and function of the avian retinopetal system, the isthmo-optic (IO) system, by means of various methods. We revealed that lesions of ION impair target selection for visually guided beak-reaching. Furthermore, we clarified that the IO neurons fire before onset of head saccades toward their receptive field. Additionally, we indicated the possibility that bipolar cell could be the target for the IO target cells. Thus these results indicate how selective attention may contribute to visually guided behavior via the IO system.
