Here we compiled data from two labs (UC Berkley[1] & MCW) to create an AOSLO-specific deviation mapping tool for measures of the foveal cone mosaic. Foveal cones were identified for 87 normative regions of interest (ROIs) (26M, 61F; 13-67 yrs, median=26 yrs) and for 5 pathological ROIs (2 Bornholm Eye Disease, 3 Albinism; 1M, 4F; 16-50 yrs, median=42 yrs). ROIs were cropped and resized to a common scale for comparison. Density and nearest neighbor distance (NND) maps were generated for each ROI, and the cone density centroid[2] (CDC) was determined for each map. Normative maps were aligned using these CDC locations, and average and standard deviation (SD) maps were created for both density and NND. Pathology maps were compared to these normative composite maps. At the CDC, average (SD) density was 1.79E+5 (2.55E+4) cones/mm^2 and average (SD) NND was 2.08 (0.16) µm. For pathological ROIs, the percentage of pixels within 1 SD of the normative data was comparable for density and NND except in two individuals where density was more deviant than NND (consistent with mosaic irregularity and/or random cone loss). Deviation mapping applied to foveal AOSLO data can be used to assess the normality of individual foveal ROIs. Comparing deviation maps across different metrics may provide valuable insight into the underlying properties of the cone mosaic in various retinal pathologies. 1) PMID:31348002 2) PMID:34343479.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"27"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144013257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we investigate the colour statistics of objects, and the brain regions that are responsive to these statistics. First, we analysed the Natural Scenes Dataset (NSD), a 7T dataset in which 8 participants viewed up to 10,000 natural scenes. Our analysis of the chromaticities of the 80 segmented object classes and backgrounds confirmed that object pixels were warmer, redder, more saturated and darker than background pixels. The probability that pixels were from objects rather than backgrounds (the 'Object Colour Probability', OCP) was calculated for 240 hue bins. The mean OCP of images correlated with NSD BOLD responses mostly in the ventral visual pathway. Other image statistics (e.g., number of food pixels) better explained the responses of correlated voxels. A second fMRI study, in which colours were shown as a single patch on a grey background, was analysed to study whether ventral visual pathway is responsive to OCP in the absence of other scene statistics. To constrain our analyses to functionally relevant areas, we used independent functional localizers to identify colour- and object-selective areas and combined these with NSD defined OCP responsive areas. The OCP of the colour patches significantly correlated with BOLD in colour-selective but not object-selective visual regions. Implications for the role of colour in object vision are discussed.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"38"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144006117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the decision processes that humans use in covert (single fixation) search with briefly presented displays having well-separated potential target locations. Performance was compared with the Bayesian-optimal decision process under the assumption that the information from the different potential target locations is statistically independent. Surprisingly, humans performed slightly better than optimal, despite humans' substantial loss of sensitivity in the fovea (\"foveal neglect\") and the implausibility of the human brain replicating the optimal computations. We show that three factors can quantitatively explain these seemingly paradoxical results. Most importantly, simple and fixed heuristic decision rules reach near optimal search performance. Second, foveal neglect primarily affects only the central potential target location. Finally, spatially correlated neural noise can cause search performance to exceed that predicted for independent noise. These findings have broad implications for understanding visual search tasks and other identification tasks in humans and other animals.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 4","pages":"5"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12007678/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144036764","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}

Past studies, however, have not varied the intensity of those colors to determine how the perception of temperature is influenced. To test this, we used four colored lights that were varied over five intensity levels. 20 young healthy subjects with normal color vision were tested. An optical system with a Xenon-arc light source, interference filters (peak l = 470, 516, 572, 652 nm), and a circular neutral density wedge to vary intensity were used. Temperature perception was assessed using an ordinal scale from - 5 (coolest) to +5 (warmest). The order of the colors used and the intensity levels were varied randomly. Considering the average across power levels, B (-1.87) and Y (+1.09) were considered the coolest, whereas G (+2.1) and R (+3.75) were considered the warmest colors. All colors, however, warmed with increasing intensity. A linear regression fit to the averaged data across luminance explained the majority of the variance: B (r2 = 0.78), Y (r2 = 0.93), G (r2 = 0.98) and R (r2 = 0.92). For example, the average rating for B went from -2.3 at the lowest intensity to -1.6 at the highest intensity. Like others, our data show that color is significantly (p<0.001) linked with temperature perception. Increasing the luminance of colors, however, consistently skews the perception toward increased warmth.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"44"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144036767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in blind humans functional properties of neurons cannot be tested directly by measuring neural responses to visual input. A possible solution is based on the idea that functionally similar neurons tend to be more correlated also in the resting condition. Here we present a method to infer the orientation preference map from spontaneous activity recorded with a Utah array from the primary visual cortex of non-human primates. We validated this methods first in a detailed model of primary visual cortex, and subsequently on Utah array recordings from macaque V1. Finally, we applied this method to recordings from blind human volunteers implanted with a cortical visual prosthesis and found that both spatial and functional properties of the set of stimulated electrodes affect perception. Particularly, discrimination between two stimuli becomes easier the more spatially and functionally separated the two sets of stimulated sites are, demonstrating the functional relevance of the decoded visual representations on electrically evoked human perception.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"10"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144029024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These outcomes are known to affect healthy aging and can be associated with accelerated cognitive decline. Here, we explore how cognitive and physical changes in central vision loss compare with sighted controls. Participants with macular-affecting pathologies (MAP) and age-matched sighted controls were recruited in both the USA and UK. Cognitive function was assessed using an adapted version of the Montreal Cognitive Assessment validated for the visually impaired, the MoCA-Blind. Physical and lifestyle activity levels were evaluated using several measures, including the Timed Up-and-Go functional balance instrument and/or the augmented Victoria Longitudinal Study (aVLS) activities questionnaire. Information about the nature and extent of visual impairment was also collected. Preliminary findings reveal a complex relationship between these variables; visual status (MAP vs sighted control) and physical and lifestyle activity levels - as assessed by the aVLS questionnaire - predicted MoCA-Blind scores, with the MAP group scoring significantly lower on aVLS activity measures. Interestingly, MoCA-Blind scores were not predicted by the Timed Up-and-Go test after controlling for age.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"42"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144041847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
