The photoreceptor is called ipRGC (intrinsically photosensitive retinal ganglion cell). The cells contain a photopigment called melanopsin, which has been reported to contribute to circadian rhythms and the pupillary light reflex. It has been also reported to contribute to mood, migraine pain and glare perception. Previous studies have used genetically modified animals to investigate the function of the cells in the brain. On the other hand, there are few studies on humans. In this talk, we will introduce the studies that have examined the effects of melanopsin cells on brightness perception in human and outline the research questions for future research.<\/p>\n\n\n\n<p>CV: Professor Sei-ichi Tsujimura<\/p>\n\n\n\n<p>Professor Tsujimura\u2019s research work is concerned primarily with the analysis and understanding of human vision and has been carried out mainly through psychophysical investigations, non-invasive measurement of involuntary signals and mathematical modelling of visual mechanisms. Recently, he has focused more on the investigation of a functional role of melanopsin cells (ipRGC) in the brain, which play an important role for adjustment of circadian rhythm, brightness perception, pupillary light reflex, mood and working memory.<\/p>\n\n\n\n<p>Professional experience<br>\u30fb Professor in Nagoya City University, Japan<br>\u30fb Professor in Kagoshima University, Japan<br>\u30fb Associate Professor in Kagoshima University Japan<br>\u30fb Research assistant in Max Plank Institute for brain research, Germany<br>(Johann Wolfgang Goethe-Universit\u00e4t Frankfurt am Main)<br>\u30fb Research Fellow in Department of Clinical Sciences, SUNY College of Optometry<br>\u30fb Postdoctoral research fellow in Aston University in UK<br>\u30fbAssociate researcher in Tsukuba University in Japan<br>\u30fb Engineer of digital signal processing, Toshiba Co., Japan<br>\u30fb National Defense Academy, Japan<\/p>\n\n\n\n<p>Qualifications<br>Ph.D.: University of Tsukuba, March 1999<br>MA: Engineering: University of Tsukuba, March 1995<\/p>\n\n\n\n<p>Awards (English)<br>Loewenfeld lecture (Key-note speech), International Pupil Colloquium, Morges, Switzerland, 2017<\/p>\n","protected":false},"featured_media":0,"template":"","acf":[],"_links":{"self":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/event\/1130"}],"collection":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/event"}],"about":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/types\/event"}],"wp:attachment":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/media?parent=1130"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
