Effective treatment of this visual disorder, amblyopia, with patching therapy is limited by a short and early critical period, as well as by poor compliance with prescribed treatment. Temporary pharmacological inactivation of the dominant eye has emerged as a means to rapidly correct the effects of monocular deprivation in animal models. Recovery occurs at older ages, and inactivation causes no apparent damage to neural connections within the primary visual pathway. It is unclear what mechanisms protect synaptic connections serving the inactivated eye. Astrocytes are important for the development and maintenance of synapses throughout the nervous system, and can compensate for a prolonged decrease in neural activity. The aim of the current study was to investigate a possible role for astrocytes in mediating the protection of neural connections following monocular inactivation. A significant increase in immunolabeling for glial fibrillary acidic protein (GFAP), a marker for astrocyte activation, was measured within inactivated-eye layers of the dorsal lateral geniculate nucleus from otherwise normal animals. Elevated levels of GFAP persisted even after the period of inactivation wore off, and GFAP was not significantly elevated following monocular deprivation by lid closure. These results implicate astrocyte activation as a possible mechanism that mediates the safeguarding of neural connections during monocular retinal inactivation. The viability of retinal inactivation as a safe and effective treatment for human amblyopia is facilitated by advancing the understanding of its effects within the visual system.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"230 ","pages":"Article 108583"},"PeriodicalIF":1.5,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143578757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The distinction between luminance and contrast processing is revealed in its most striking form by the contrast asynchrony paradigm: two discs with bright and dark surrounds modulate in luminance. When the discs modulate at 3–6 Hz, there is a percept of antiphase flicker even though the luminance modulation of the patches is in phase. To establish the neural basis of this perceptual phenomenon, we conducted a study using steady-state visual evoked potentials (SSVEPs) aiming to identify specific contrast and luminance signals. Deconstructing contrast asynchrony into its constituent elements, we displayed eight discs modulating sinusoidally from dark to bright on one of three backgrounds (bright, midgray, dark).

With lower contrast modulation at 3 Hz, SSVEP amplitudes and phases correspond to the temporal signatures of contrast — not luminance — modulation. However, at higher frequencies and/or contrasts, this orderly pattern was largely replaced by more complex patterns that no longer directly corresponded to the luminance or contrast of the stimulus.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"230 ","pages":"Article 108567"},"PeriodicalIF":1.5,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143561802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The evidence from cortical evoked responses also supports the concept that the cortex does away with the strict segregation of color and luminance signals, and of red-green vs blue-yellow signals, that is present in its thalamic input. Rather, all combinations of cardinal direction signals are used by the population of spatially-tuned, color-responsive cortical neurons in the visual cortex. The neural populations that combine color signals are sometimes called Higher Order Color Mechanisms. These fundamental findings about color processing in the cortex challenge the classical theory of opponent colors.

However, several psychophysical studies found no compelling association between these illusions, calling this hypothesis into question. Here we ask if these discrepant reports could arise from methodological differences between these studies. We ran a battery of visual size illusion and basic discrimination tasks with carefully matched geometric properties, using a classic forced-choice design. In our small, homogenous sample, the Ebbinghaus and Delboeuf illusion magnitudes were strongly correlated, consistent with the idea that they reflect the same underlying mechanism when other sources of individual differences are minimised. Ponzo illusion magnitude also correlated with these two illusions, although less strongly in the case of the Ebbinghaus. Interestingly, the classic arrowhead version of the Mueller-Lyer illusion did not correlate with any of the other illusions or even with the objective ability to discriminate line length. This suggests that an altogether separate process underlies this perceptual effect. We further demonstrate that presenting stimuli briefly with central fixation critically affects measurements of the Ebbinghaus illusion. Additionally, we found that measuring illusion magnitude via adjustment is less reliable compared to two-alternative forced-choice procedures. Taken together, our findings suggest that different tasks probe separable processes determining illusion measurements. They further highlight the importance of the experimental design when testing relationships between perceptual effects and their links to neural processing.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"229 ","pages":"Article 108566"},"PeriodicalIF":1.5,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143479947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
