Multiple gamma rhythms carry distinct spatial frequency information in primary visual cortex

C Han, T Wang, Y Yang, Y Wu, Y Li, W Dai… - PLoS …, 2021 - journals.plos.org
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 …

Luminance contrast shifts dominance balance between ON and OFF pathways in human vision

H Rahimi-Nasrabadi, V Moore-Stoll, J Tan… - Journal of …, 2023 - jneurosci.org

Cortical mechanisms of visual brightness

R Mazade, J **, H Rahimi-Nasrabadi, S Najafian… - Cell reports, 2022 - cell.com
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 …

Cortical balance between ON and OFF visual responses is modulated by the spatial properties of the visual stimulus

M Jansen, J **, X Li, R Lashgari, J Kremkow… - Cerebral …, 2019 - academic.oup.com
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 …

S Poudel, H Rahimi-Nasrabadi, J **… - Journal of …, 2023 - tvst.arvojournals.org
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 …

Voltage-sensitive dye imaging of transcranial magnetic stimulation-induced intracortical dynamics

V Kozyrev, UT Eysel, D Jancke - Proceedings of the National Academy of …, 2014 - pnas.org

neuroscience. Additionally, it has become a powerful tool to drive plastic changes in …

Functional specialization of ON and OFF cortical pathways for global-slow and local-fast vision

R Mazade, J **, C Pons, JM Alonso - Cell Reports, 2019 - cell.com
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 …
