The time course of chromatic adaptation under immersive illumination

G Gupta, N Gross, R Pastilha, A Hurlbert - BioRxiv, 2020 - biorxiv.org
Chromatic adaptation is a major contributory mechanism to constancy, yet its extent
depends on many factors-spectral, spatial and temporal-which vary between studies and …

[HTML][HTML] fMRI representational similarity analysis reveals graded preferences for chromatic and achromatic stimulus contrast across human visual cortex

E Goddard, KT Mullen - NeuroImage, 2020 - Elsevier
Human visual cortex is partitioned into different functional areas that, from lower to higher,
become increasingly selective and responsive to complex feature dimensions. Here we use …

[HTML][HTML] Visual mode switching: Improved general compensation for environmental color changes requires only one exposure per day

Y Li, KEM Tregillus, SA Engel - Journal of vision, 2022 - jov.arvojournals.org
When the visual environment changes, vision adapts in order to maintain accurate
perception. For repeatedly encountered environmental changes, the visual system may …

[HTML][HTML] Reconstructing sources location of visual color cortex by the task-irrelevant visual stimuli through machine learning decoding

Y Wu, Y Zhang, Y Mao, K Feng, D Wei, L Song - Heliyon, 2022 - cell.com
Visual color sensing is generated by electrical discharges from endocranial neuronal
sources that penetrate the skull and reach to the cerebral cortex. However, the space …

[HTML][HTML] Attention selectively enhances stimulus information for surround over foveal stimulus representations in occipital cortex

E Goddard, KT Mullen - Journal of Vision, 2021 - jov.arvojournals.org
By attending to part of a visual scene, we can prioritize processing of the most relevant
visual information and so use our limited resources effectively. Previous functional magnetic …
