In vivo images of the photoreceptor mosaic acquired using an Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO) are systematically distorted by eye motion. Most methods to extract FEMs from AOSLO data rely on comparison to a motion-free reference, giving eye-position as a function of time. MS are subsequently identified using adaptive velocity thresholds (Engbert & Kliegl, 2003). We use computer vision and machine learning (ML) for detection and characterisation of MS directly from raw AOSLO images. For training and validation, we use Emulated Retinal Image CApture (ERICA), an open-source tool to generate synthetic AOSLO datasets of retinal images and ground-truth velocity profiles (Young & Smithson, 2021). To classify regions of AOSLO images that contain a MS, images were divided into a grid of 32-by-32-pixel sub-images. Predictions from rows of sub-images aligned with the fast-scan of the AOSLO were combined, giving 1ms resolution. Model performance was high (F1 scores >0.92) across plausible MS displacement magnitudes and angles, with most errors close to the velocity threshold for classification. Direct velocity predictions were also derived from regression ML models. We show that ML models can be systematically adapted for generalisation to real in vivo images, allowing characterisation of MS at much finer spatial scales than video-based eye-trackers.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"5"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144039692","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}

In change-detection tasks, items are encoded into memory and, after a retention period, are compared against a test set. Loss of information can occur from attentional interference or prioritizing some items over others. But what happens to the memory representations after the change-detection task is completed? The current article examines the fate of a memory item after its behavioral purpose has been fulfilled. Participants encoded a single item in memory for a difficult change-detection task. Visual search trials were presented both before and after the memory test was completed. Singleton distractors were present in these search trials that could match or not the memory item. In Experiment 1, memory-driven capture (the memory-matching distractors led to longer search response times than the unrelated distractor) was observed in the pre-memory test and, in a weaker form, the post-test search trials. In Experiment 2, we introduced cues that indicated the memory test would not occur on a subset of trials, controlling for re-exposure to the memory stimulus. Memory-driven capture was again observed for these post-cue search trials, but only at a short time interval, at a longer interval this effect was attenuated. These results suggest that the memory representations only linger briefly in the visual system.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 4","pages":"7"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12011125/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144054431","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}

Melanopsin activation takes longer to peak and has a prolonged response relative to cone photoreceptors. Recent evidence suggests that melanopsin-driven signals may influence vision (through cone photoreceptor modulation), but it is unclear whether melanopsin can directly stimulate visual cortex (e.g. V1), in addition to subcortical pathways. Our lab recently observed unusual fMRI time course responses in V1 for S-cone isolating stimuli, where the response was maintained for the duration of the stimulus 'off' period - it did not return to baseline after stimulus offset (at 12 seconds). We hypothesised that this was due to an effect of lingering melanopsin activation, which was activated by the S-cone isolating stimuli because we did not explicitly silence melanopsin in that study. In the present study, we used a custom-made multi-primary LED system, to create S-cone isolating stimuli that either activated or silenced melanopsin. Stimuli were presented in a block design, 15s ON / 30s OFF to allow time for a sustained response to return to baseline between conditions. Here we present evidence from 11 participants of melanopsin-driven responses in cortical area V1 - where the S-cone melanopsin-active condition showed a larger response after stimulus offset than the S-cone melanopsin-silenced condition.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"22"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144054830","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}

A stable neuronal representation of light intensity is grounded in a specialised retinal output channel, found in humans and other mammals, and arising from intrinsically photosensitive retinal ganglion cells (ipRGCs). These are a rare class of retinal ganglion cells with autonomous sensitivity to light, thanks to their expression of the photopigment melanopsin. Melanopsin photoreception is optimised to encode low-frequency changes in the light environment and, as a result, extends the temporal and spatial range over which light is detected by the retina. ipRGCs innervate many brain areas, and this allows melanopsin light responses to be used for diverse purposes, ranging from the synchronization of the circadian clock with the solar day to light's regulation of mood, alertness, and neuroendocrine and cognitive functions. There is now also abundant evidence that ipRGCs also make an important contribution to the processes of perceptual vision, via their projection to the visual thalamus. Here I will discuss ongoing research exploring how melanopsin extends the spatial and temporal range over which light is detected by the retina, and the role this plays in augmenting the detection of patterns in brightness.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"53"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144038424","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}

The goal is to characterise the flow of information across the brain from sensory input areas through to motor outputs, and the way that this information flow can be modulated by priors. Our lab is translating the IBL task to humans using a combination of psychophysics and neuroimaging. Here we describe the results from a pilot study using a novel type of neuroimaging (OPM-MEG). We first describe the adaptations necessary to alter the original rodent task to make it appropriate for human subjects. We then present behavioral and neuroimaging data obtained using this modified paradigm. Human psychophysical responses recapitulate key features of the rodent behavioural data - including the effect of perceptual priors or 'bias'. Psychophysical response functions have the same form and bias dependency as those obtained from mice. Using the MEG data we are able to decode key features of the IBL paradigm including visual stimuli, responses, bias blocks and feedback in a time-resolved manner. We show that OPM-MEG responses are consistent with fMRI responses obtained in our lab using the same paradigm. We conclude that multimodal neuroimaging techniques (OPM-MEG and fMRI) can be applied to the IBL task allowing us to relate neuronal-level recordings in rodents with whole-brain population responses in humans.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"15"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144058554","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 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}
