Multiple gamma rhythms carry distinct spatial frequency information in primary visual cortex
Gamma rhythms in many brain regions, including the primary visual cortex (V1), are thought
to play a role in information processing. Here, we report a surprising finding of 3 narrowband …

Image luminance changes contrast sensitivity in visual cortex
Accurate measures of contrast sensitivity are important for evaluating visual disease
progression and for navigation safety. Previous measures suggested that cortical contrast …

Cortical mechanisms of visual brightness
The primary visual cortex signals the onset of light and dark stimuli with ON and OFF cortical
pathways. Here, we demonstrate that both pathways generate similar response increments …

[HTML][HTML] Differences in visual stimulation between reading and walking and implications for myopia development
Visual input plays an important role in the development of myopia (nearsightedness), a
visual disorder that blurs vision at far distances. The risk of myopia progression increases …

Cortical balance between ON and OFF visual responses is modulated by the spatial properties of the visual stimulus
The primary visual cortex of carnivores and primates is dominated by the OFF visual
pathway and responds more strongly to dark than light stimuli. Here, we demonstrate that …

Luminance contrast shifts dominance balance between ON and OFF pathways in human vision
H Rahimi-Nasrabadi, V Moore-Stoll, J Tan… - Journal of …, 2023 - Soc Neuroscience
Human vision processes light and dark stimuli in visual scenes with separate ON and OFF
neuronal pathways. In nature, stimuli lighter or darker than their local surround have different …

Induction of excitatory brain state governs plastic functional changes in visual cortical topology
Adult visual plasticity underlying local remodeling of the cortical circuitry in vivo appears to
be associated with a spatiotemporal pattern of strongly increased spontaneous and evoked …

Functional specialization of ON and OFF cortical pathways for global-slow and local-fast vision
Visual information is processed in the cortex by ON and OFF pathways that respond to light
and dark stimuli. Responses to darks are stronger, faster, and driven by a larger number of …
