    Among vertebrates, birds have a particularly well-developed retinopetal system, i.e., the centrifugal system projecting from the brain to the retina. Primary, secondary and tertiary neurons of the retinopetal system connect serially in a one-to-one-to-one fashion, thereby assembling several thousand retinopetal modules projecting in parallel to the retina. The signal conveyed by the retinopetal system enhances the visual responses of retinal ganglion cells (RGCs), and each retinopetal module may facilitate the RGCs in a topographically restricted area. We investigated how the retinopetal signal contributes to visual search by first training Japanese quail to search and peck a target stimulus presented on one of three touch-sensor monitors around the bird and then examining the effect of retinopetal signal blockage on the task. Our results indicate that the retinopetal signal improves both stimulus detectability and target discriminability. Thus, this study confirms that the avian retinopetal system functions specifically in attentional facilitation of the retina; this new finding suggests that this system benefits early detection and late selection phases of visual search. The fast and precise target detection facilitated by the retinopetal signal may be transformed into quick and correct orienting to the target through visuomotor transformation mechanisms implemented in the optic tectum.

    Birds have a well-developed retinopetal system projecting from the midbrain to the contralateral retina. The signal sent to the retina through the retinopetal system facilitates visual responses of the retinal ganglion cells (RGCs), and the retinopetal signals function as attentional signals during visual search. Thus, the retinopetal signal somehow reaches and facilitates visual responses of the RGCs. However, the tertiary neuron of the retinopetal system, the isthmo-optic target cell (IOTC), is unlikely to contact most RGCs directly, because the IOTCs form axon terminals localized in the outermost sublayer (lamina 1) of the inner plexiform layer (IPL) where few RGC dendrites terminate. Therefore, some other intrinsic retinal neurons must be involved in the centrifugal attentional enhancement of visual responses of the RGCs. We investigated connections of the target cells of the IOTCs in chicken and quail, using light and electron microscopic immunohistochemistry. We show that axon terminals of the IOTC make synaptic contacts with protein kinase Cα (PKCα)-immunoreactive (ir) bipolar cells (PKCα-BCs) in lamina 1 of the IPL. Furthermore, with prolonged electrical stimulation of the isthmo-optic nucleus (ION) on one side, whose neurons send their axons to the contralateral retina and make synaptic contacts there with IOTCs, phosphorylation of cAMP response element-binding protein was observed in the PKCα-BCs in the contralateral retina, but not in the ipsilateral retina. This suggests that electrical stimulation of ION activated PKCα-BCs through synapses from IOTCs to PKCα-BCs, thus stimulating transcription in PKCα-BCs. Thus, centrifugal attentional signals may facilitate visual responses of RGCs via the PKCα-BCs.

    Active Learning is a generic term for teaching and learning method that incorporates the active participation of students. We have created 50 or more preparation videos for active learning using Information and Communication Technology (ICT). In this study, we will report on how to create a preparation videos, the delivery method of them and the flipped classroom using them.

    The avian brains have a well-developed centrifugal control system (the isthmo-optic system) of the contralateral retina. Various evidences revealed that the isthmo-optic signals sending to the retina enhance retinal outputs locally and transiently, functioning as spatial attention. In the present study, we reversibly blocked the isthmo-optic signals by pharmacological inactivation of the isthmo-optic neurons. We assembled three touch displays to present a target letter and distracters in a very wide visual field of quail, and trained quails to reach the target letter with a beak. Blocking of the isthmo-optic signals decreased selection accuracy of the targets that were presented in the visual field contralateral to the injection side (= affected side of inactivation), but increased that of the targets that were presented in the visual field ipsilateral to the injection side. Thus, the isthmo-optic systems of both sides may compete with each other for enhancement of the retinal output of a particular side.
