Objective To review clinical and pre-clinical evidence supporting the role of visual pathways,
from the eye to the cortex, in the development of photophobia in headache disorders …

Our visual system uses contextual cues to estimate the brightness of surfaces: brightness
can shift towards (assimilation) or away from (contrast) the brightness of the surround. We …

Mechanisms of light adaptation have been traditionally explained with reference to
psychophysical experimentation. However, the neural substrata involved in those …

We explored the complexity of the light adaptation process, assessing adaptation recovery
(Ar) at different eccentricities and light levels. Luminance thresholds were obtained with …

We assessed how rod excitation (R) affects luminance (L+ M+ S) and chromatic [L/(L+ M)]
reaction times (RTs). A four-primary display based on the overlapped images of two …
