In visual cortex, stimulation outside the classical receptive field can decrease neural activity and also decrease functional Magnetic Resonance Imaging (fMRI) signal amplitudes. Decreased fMRI amplitudes below baseline-0% contrast-are often referred to as \"negative\" responses. Using neural model-based fMRI data analyses, we can estimate the region of visual space to which each cortical location responds, i.e., the population receptive field (pRF). Current models of the pRF do not account for a center-surround organization or negative fMRI responses. Here, we extend the pRF model by adding surround suppression. Where the conventional model uses a circular symmetric Gaussian function to describe the pRF, the new model uses a circular symmetric difference-of-Gaussians (DoG) function. The DoG model allows the pRF analysis to capture fMRI signals below baseline and surround suppression. Comparing the fits of the models, an increased variance explained is found for the DoG model. This improvement was predominantly present in V1/2/3 and decreased in later visual areas. The improvement of the fits was particularly striking in the parts of the fMRI signal below baseline. Estimates for the surround size of the pRF show an increase with eccentricity and over visual areas V1/2/3. For the suppression index, which is based on the ratio between the volumes of both Gaussians, we show a decrease over visual areas V1 and V2. Using non-invasive fMRI techniques, this method gives the possibility to examine assumptions about center-surround receptive fields in human subjects.", "publicationTitle": "Journal of vision", "publisher": "", "place": "", "date": "2012", "volume": "12", "issue": "3", "section": "", "partNumber": "", "partTitle": "", "pages": "10", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "J Vis", "DOI": "10.1167/12.3.10", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1534-7362", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "eng", "libraryCatalog": "NCBI PubMed", "callNumber": "", "rights": "", "extra": "PMID: 22408041", "tags": [ { "tag": " Neurological", "type": 1 }, { "tag": "zrread" } ], "collections": [ "W95KP9WG" ], "relations": {}, "dateAdded": "2014-02-14T20:42:48Z", "dateModified": "2014-11-26T20:19:14Z" } }, { "key": "RVCDT66T", "version": 2922, "library": { "type": "user", "id": 512326, "name": "patrickmineault", "links": { "alternate": { "href": "https://www.zotero.org/patrickmineault", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/users/512326/items/RVCDT66T", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/patrickmineault/items/RVCDT66T", "type": "text/html" } }, "meta": { "creatorSummary": "Komban et al.", "parsedDate": "2014", "numChildren": 1 }, "data": { "key": "RVCDT66T", "version": 2922, "itemType": "journalArticle", "title": "Neuronal and Perceptual Differences in the Temporal Processing of Darks and Lights", "creators": [ { "creatorType": "author", "firstName": "Stanley Jose", "lastName": "Komban" }, { "creatorType": "author", "firstName": "Jens", "lastName": "Kremkow" }, { "creatorType": "author", "firstName": "Jianzhong", "lastName": "Jin" }, { "creatorType": "author", "firstName": "Yushi", "lastName": "Wang" }, { "creatorType": "author", "firstName": "Reza", "lastName": "Lashgari" }, { "creatorType": "author", "firstName": "Xiaobing", "lastName": "Li" }, { "creatorType": "author", "firstName": "Qasim", "lastName": "Zaidi" }, { "creatorType": "author", "firstName": "Jose-Manuel", "lastName": "Alonso" } ], "abstractNote": "Visual information is mediated by two major thalamic pathways that signal light decrements (OFF) and increments (ON) in visual scenes, the OFF pathway being faster than the ON.

For some animals, song structure can vary considerably from one rendition to the next; neural noise within pattern generating circuits is widely assumed to be the primary source of such variability, and statistical models that incorporate neural noise are successful at reproducing the full variation present in natural songs. In direct contrast, here we demonstrate that much of the pattern variability in Drosophila courtship song can be explained by taking into account the dynamic sensory experience of the male. In particular, using a quantitative behavioural assay combined with computational modelling, we find that males use fast modulations in visual and self-motion signals to pattern their songs, a relationship that we show is evolutionarily conserved. Using neural circuit manipulations, we also identify the pathways involved in song patterning choices and show that females are sensitive to song features.

In particular, the invariance of complex cell responses in primary visual cortex against small translations is commonly interpreted as a signature of an invariant coding strategy possibly originating from an unsupervised learning principle. Various models have been proposed to explain the response properties of complex cells using a sparsity or a slowness criterion and it has been concluded that physiologically plausible receptive field properties can be derived from either criterion. Here, we show that the effect of the two objectives on the resulting receptive field properties is in fact very different. We conclude that slowness alone cannot explain the filter shapes of complex cells and discuss what kind of experimental measurements could help us to better asses the role of slowness and sparsity for complex cell representations.", "publicationTitle": "PLoS Comput Biol", "publisher": "", "place": "", "date": "2014", "volume": "10", "issue": "3", "section": "", "partNumber": "", "partTitle": "", "pages": "e1003468", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "PLoS Comput Biol", "DOI": "10.1371/journal.pcbi.1003468", "citationKey": "", "url": "http://dx.doi.org/10.1371/journal.pcbi.1003468", "accessDate": "2014-03-17T20:26:12Z", "PMID": "", "PMCID": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "PLoS Journals", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "W95KP9WG" ], "relations": {}, "dateAdded": "2014-03-17T20:26:12Z", "dateModified": "2014-03-20T16:25:38Z" } }, { "key": "35AD9CKH", "version": 2818, "library": { "type": "user", "id": 512326, "name": "patrickmineault", "links": { "alternate": { "href": "https://www.zotero.org/patrickmineault", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/users/512326/items/35AD9CKH", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/patrickmineault/items/35AD9CKH", "type": "text/html" } }, "meta": { "creatorSummary": "Heitz et al.", "parsedDate": "2008", "numChildren": 0 }, "data": { "key": "35AD9CKH", "version": 2818, "itemType": "conferencePaper", "title": "Cascaded Classification Models: Combining Models for Holistic Scene Understanding.", "creators": [ { "creatorType": "author", "firstName": "Geremy", "lastName": "Heitz" }, { "creatorType": "author", "firstName": "Stephen", "lastName": "Gould" }, { "creatorType": "author", "firstName": "Ashutosh", "lastName": "Saxena" }, { "creatorType": "author", "firstName": "Daphne", "lastName": "Koller" } ], "abstractNote": "", "proceedingsTitle": "NIPS", "conferenceName": "", "publisher": "Vancouver, BC", "place": "", "date": "2008", "eventPlace": "", "volume": "1", "issue": "", "numberOfVolumes": "", "pages": "2", "series": "", "seriesNumber": "", "DOI": "", "ISBN": "", "citationKey": "", "url": "https://papers.nips.cc/paper/3472-cascaded-classification-models-combining-models-for-holistic-scene-understanding.pdf", "accessDate": "2014-03-19T02:01:49Z", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "Cascaded Classification Models", "language": "", "libraryCatalog": "Google Scholar", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [ "W95KP9WG" ], "relations": {}, "dateAdded": "2014-03-19T02:01:49Z", "dateModified": "2014-03-20T16:25:27Z" } }, { "key": "62NVC3EB", "version": 2817, "library": { "type": "user", "id": 512326, "name": "patrickmineault", "links": { "alternate": { "href": "https://www.zotero.org/patrickmineault", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/users/512326/items/62NVC3EB", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/patrickmineault/items/62NVC3EB", "type": "text/html" } }, "meta": { "creatorSummary": "Neumann and Sepp", "numChildren": 2 }, "data": { "key": "62NVC3EB", "version": 2817, "itemType": "journalArticle", "title": "Recurrent V1–V2 interaction in early visual boundary processing", "creators": [ { "creatorType": "author", "firstName": "Heiko", "lastName": "Neumann" }, { "creatorType": "author", "firstName": "Wolfgang", "lastName": "Sepp" } ], "abstractNote": "A majority of cortical areas are connected via feedforward and feedback fiber projections. In feedforward pathways we mainly observe stages of feature detection and integration. The computational role of the descending pathways at different stages of processing remains mainly unknown. Based on empirical findings we suggest that the top-down feedback pathways subserve a context-dependent gain control mechanism. We propose a new computational model for recurrent contour processing in which normalized activities of orientation selective contrast cells are fed forward to the next processing stage. There, the arrangement of input activation is matched against local patterns of contour shape. The resulting activities are subsequently fed back to the previous stage to locally enhance those initial measurements that are consistent with the top-down generated responses. In all, we suggest a computational theory for recurrent processing in the visual cortex in which the significance of local measurements is evaluated on the basis of a broader visual context that is represented in terms of contour code patterns. The model serves as a framework to link physiological with perceptual data gathered in psychophysical experiments. It handles a variety of perceptual phenomena, such as the local grouping of fragmented shape outline, texture surround and density effects, and the interpolation of illusory contours.", "publicationTitle": "Biological Cybernetics", "publisher": "", "place": "", "date": "1", "volume": "81", "issue": "5-6", "section": "", "partNumber": "", "partTitle": "", "pages": "425-444", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Biol Cybern", "DOI": "10.1007/s004220050573", "citationKey": "", "url": "http://link.springer.com/article/10.1007/s004220050573", "accessDate": "2014-03-12T03:09:32Z", "PMID": "", "PMCID": "", "ISSN": "0340-1200, 1432-0770", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "link.springer.com", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "_tablet" } ], "collections": [ "W95KP9WG" ], "relations": {}, "dateAdded": "2014-03-12T03:09:32Z", "dateModified": "2014-03-20T16:25:16Z" } }, { "key": "BB4K9ZIV", "version": 2808, "library": { "type": "user", "id": 512326, "name": "patrickmineault", "links": { "alternate": { "href": "https://www.zotero.org/patrickmineault", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/users/512326/items/BB4K9ZIV", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/patrickmineault/items/BB4K9ZIV", "type": "text/html" } }, "meta": { "creatorSummary": "Liu et al.", "parsedDate": "2010", "numChildren": 2 }, "data": { "key": "BB4K9ZIV", "version": 2808, "itemType": "conferencePaper", "title": "Single image depth estimation from predicted semantic labels", "creators": [ { "creatorType": "author", "firstName": "Beyang", "lastName": "Liu" }, { "creatorType": "author", "firstName": "S.", "lastName": "Gould" }, { "creatorType": "author", "firstName": "D.", "lastName": "Koller" } ], "abstractNote": "We consider the problem of estimating the depth of each pixel in a scene from a single monocular image. Unlike traditional approaches, which attempt to map from appearance features to depth directly, we first perform a semantic segmentation of the scene and use the semantic labels to guide the 3D reconstruction. This approach provides several advantages: By knowing the semantic class of a pixel or region, depth and geometry constraints can be easily enforced (e.g., “sky” is far away and “ground” is horizontal). In addition, depth can be more readily predicted by measuring the difference in appearance with respect to a given semantic class. For example, a tree will have more uniform appearance in the distance than it does close up. Finally, the incorporation of semantic features allows us to achieve state-of-the-art results with a significantly simpler model than previous works.", "proceedingsTitle": "2010 IEEE Conference on

Use of a single image set to systematically compare free viewing to other tasks has never been performed. We investigated the effect of task differences on the ability of three models of saliency to predict the performance of humans viewing a novel database of 800 natural images. We introduced a novel task where 100 observers made explicit perceptual judgments about the most salient image region. Other groups of observers performed a free viewing task, saliency search task, or cued object search task. Behavior on the popular free viewing task was not best predicted by standard saliency models. Instead, the models most accurately predicted the explicit saliency selections and eye movements made while performing saliency judgments. Observers' fixations varied similarly across images for the saliency and free viewing tasks, suggesting that these two tasks are related. The variability of observers' eye movements was modulated by the task (lowest for the object search task and greatest for the free viewing and saliency search tasks) as well as the clutter content of the images. Eye movement variability in saliency search and free viewing might be also limited by inherent variation of what observers consider salient. Our results contribute to understanding the tasks and behavioral measures for which saliency models are best suited as predictors of human behavior, the relationship across various perceptual tasks, and the factors contributing to observer variability in fixational eye movements.", "publicationTitle": "Journal of Vision", "publisher": "", "place": "", "date": "03/11/2014", "volume": "14", "issue": "3", "section": "", "partNumber": "", "partTitle": "", "pages": "14", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "J Vis", "DOI": "10.1167/14.3.14", "citationKey": "", "url": "http://www.journalofvision.org/content/14/3/14", "accessDate": "2014-03-17T20:28:02Z", "PMID": "", "PMCID": "", "ISSN": ", 1534-7362", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "en", "libraryCatalog": "www.journalofvision.org", "callNumber": "", "rights": "", "extra": "PMID: 24618107", "tags": [ { "tag": "Attention", "type": 1 }, { "tag": "_tablet" }, { "tag": "eye movements", "type": 1 }, { "tag": "real scenes", "type": 1 }, { "tag": "saliency", "type": 1 }, { "tag": "visual search", "type": 1 } ], "collections": [ "W95KP9WG" ], "relations": {}, "dateAdded": "2014-03-17T20:28:02Z", "dateModified": "2014-03-17T20:28:02Z" } }, { "key": "2TQH73F4", "version": 2780, "library": { "type": "user", "id": 512326, "name": "patrickmineault", "links": { "alternate": { "href": "https://www.zotero.org/patrickmineault", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/users/512326/items/2TQH73F4", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/patrickmineault/items/2TQH73F4", "type": "text/html" } }, "meta": { "creatorSummary": "Zhou et al.", "parsedDate": "2000", "numChildren": 3 }, "data": { "key": "2TQH73F4", "version": 2780, "itemType": "journalArticle", "title": "Coding of Border Ownership in Monkey Visual Cortex", "creators": [ { "creatorType": "author", "firstName": "Hong", "lastName": "Zhou" }, { "creatorType": "author", "firstName": "Howard S.", "lastName": "Friedman" }, { "creatorType": "author", "firstName": "Rüdiger von der", "lastName": "Heydt" } ], "abstractNote": "Areas V1 and V2 of the visual cortex have traditionally been conceived as stages of local feature representations. We investigated whether neural responses carry information about how local features belong to objects. Single-cell activity was recorded in areas V1, V2, and V4 of awake behaving monkeys. Displays were used in which the same local feature (contrast edge or line) could be presented as part of different figures. For example, the same light–dark edge could be the left side of a dark square or the right side of a light square. Each display was also presented with reversed contrast.\nWe found significant modulation of responses as a function of the side of the figure in >50% of neurons of V2 and V4 and in 18% of neurons of the top layers of V1. Thus, besides the local contrast border information, neurons were found to encode the side to which the border belongs (“border ownership coding”). A majority of these neurons coded border ownership and the local polarity of luminance–chromaticity contrast. The others were insensitive to contrast polarity. Another 20% of the neurons of V2 and V4, and 48% of top layer V1, coded local contrast polarity, but not border ownership. The border ownership-related response differences emerged soon (<25 msec) after the response onset. In V2 and V4, the differences were found to be nearly independent of figure size up to the limit set by the size of our display (21°). Displays that differed only far outside the conventional receptive field could produce markedly different responses. When tested with more complex displays in which figure-ground cues were varied, some neurons produced invariant border ownership signals, others failed to signal border ownership for some of the displays, but neurons that reversed signals were rare.\nThe influence of visual stimulation far from the receptive field center indicates mechanisms of global context integration. The short latencies and incomplete cue invariance suggest that the border-ownership effect is generated within the visual cortex rather than projected down from higher levels.", "publicationTitle": "The Journal of Neuroscience", "publisher": "", "place": "", "date": "2000", "volume": "20", "issue": "17", "section": "", "partNumber": "", "partTitle": "", "pages": "6594-6611", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "J.

In the model, neurons have spatially local classical receptive fields, are tuned to orientation, and receive information (from V1) about the location and orientation of borders.
