Sound localization in the horizontal plane is mainly determined by interaural time differences (ITD) and interaural level differences (ILD). Both cues result in an estimate of sound source location and in many real-life situations these two cues are roughly congruent. When stimulating listeners with headphones it is possible to counterbalance the two cues,(More)
Fetal bovine serum (FBS) or other mammal-derived factors are extensively supplemented as growth factor into culture medium. Since mammal-derived factors arouses the concern about the risk of zoonosis, serum-and mammal-free culture is strongly required. We focused on sericin hydrolysates, originating from silkworm, and reported that sericin is effective as(More)
Localization of sound sources is critical for an appropriate behavioral response. This is not only true for localization in the horizontal plane but also for localization in depth. Depth ranging of sound sources implicates various distance cues, among others sound intensity. In this study, we measured human electroencephalography and compared mismatch(More)
This research shows a novel method for hazard identification of a chemical and UV light on a single cell level with a laser probe beam. The laser probe beam was passed through interface of cell membrane/culture medium of a cultured human hepatoblastoma cell line HepG2. Deflection of the laser probe beam, which was induced by changes in concentration(More)
