Description
This thesis presents the first characterisation of the spatial and temporal visual response of the melanopsin photopigment in the human eye. To measure the spatiotemporal response of a single-photoreceptor class, a novel five-primary display and psychophysical methodology was developed which can perform pixel-by-pixel, five-photoreceptor silent substitution. The outcomes show that melanopic-mediated visual responses, independent of the canonical rod and cone pathways, can perceive spatiotemporal patterns at lower frequencies but which does not translate to conscious form vision. Melanopsin’s role is therefore to signal broad and slow visual information, creating the background upon which cone vision fills in the details.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads:
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
