| Outline of Final Research Achievements |
Two-frame movies presented with an inter-stimulus interval (ISI) between the first and second frames often induce sensation of motion in the opposite direction to the actual image shift. This phenomenon seems due to temporal filters with biphasic impulse response functions embedded in visual system. Recently, it was reported that this two-frame movie induced ocular following responses (OFRs) in the reversed direction in human, and temporal filters based on the observed data was estimated by assuming a motion energy model underlying the OFR-generation. To understand the neural substrates underlying the visual motion detectors to elicit the OFRs, it is critical to have an adequate animal model. In the present study, we applied this experimental paradigm on monkeys to disclose the temporal characteristics of the visual system and studied how similar the visual systems of humans and non-human primates are.
