DOI: 10.1016/j.visres.2019.09.010
Abstract: Both luminance contrast and character size are critical factors affecting reading performance. Previous studies reported on the effect of luminance contrast on the reading-speed function, that is, the relationship between reading speed and character size.… read more here.

DOI: 10.1038/s41467-022-28249-0
Abstract: Hue and luminance contrast are basic visual features. Here we use multivariate analyses of magnetoencephalography data to investigate the timing of the neural computations that extract them, and whether they depend on common neural circuits.… read more here.

DOI: 10.1038/s41598-020-62165-x
Abstract: A fundamental assumption of nearly all functional magnetic resonance imaging (fMRI) analyses is that the relationship between local neuronal activity and the blood oxygenation level dependent (BOLD) signal can be described as following linear systems… read more here.

DOI: 10.1038/s41598-020-65754-y
Abstract: An apparent and common feature of aposematic patterns is that they contain a high level of achromatic (luminance) contrast, for example, many warning signals combine black spots and stripes with a lighter colour such as… read more here.

DOI: 10.1098/rsos.220567
Abstract: The perception of depth from retinal images depends on information from multiple visual cues. One potential depth cue is the statistical relationship between luminance and distance; darker points in a local region of an image… read more here.

DOI: 10.1162/jocn_a_01852
Abstract: Visual working memory (WM) enables the use of past sensory experience in guiding behavior. Yet, laboratory tasks commonly evaluate WM in a way that separates it from its sensory bottleneck. To understand how perception interacts… read more here.

DOI: 10.1523/eneuro.0515-22.2023
Abstract: Abstract There is substantial variation in the mean and variance of light levels (luminance and contrast) in natural visual scenes. Retinal ganglion cells maintain their sensitivity despite this variation using two adaptive mechanisms, which control… read more here.
