The perceived configuration of a face can be strongly biased by prior adaptation to a face with a distorted configuration. These aftereffects have been found to be weaker when the adapt and test faces differ along a number of dimensions. We asked whether the adaptation shows more transfer between faces that share a common identity, by comparing the strength(More)
Sustained vertebrate vision requires that opsin chromophores isomerized by light to the all-trans form be replaced with 11-cis retinal to regenerate the visual pigment. We have characterized the early receptor potential (ERP), a component of the electroretinogram arising from photoisomerization-induced charge displacements in plasma membrane visual pigment,(More)
To quantify the response dynamics of fast adaptation mechanisms of the scotopic ERG in younger and older adults using full-field m-sequence flash stimulation. Scotopic ERGs were measured for a series of flashes separated by 65 ms over a range of 260 ms in 16 younger (20–26, 22.2 ± 2.1; range mean ±1 SD) and 16 older (65–85, 71.2 ± 7) observers without(More)
An earlier reported trial suggests that omega-3 fatty acids in fish oil supplements at 6 g/day with administration commencing at the time of engraftment may reduce acute CsA renal dysfunction. When started at the time of renal transplant, there are improvements in renal hemodynamics and blood pressure, and a decrease in rejection episodes. To examine the(More)
Purpose To investigate the topographic changes of the dark-adapted multifocal electroretinogram (mfERG) across adulthood in the central retina and compare the topography between macular versus extramacular, nasal versus temporal, and inferior versus superior retinal areas. Methods Sixty-five subjects (18-88 years) received a comprehensive dilated eye(More)
