In the periphery, a transmission bottleneck constrains performance; thus efficient coding implies that natural signal components with a predictably wider range should be compressed. In a different regime—when sampling limitations constrain performance—efficient coding implies that more resources should be allocated to informative features that are more variable. We propose that this regime is relevant for sensory cortex when it extracts complex features from limited numbers of sensory samples. To test this prediction, we use central visual processing as a model: we show that visual sensitivity for local multi-point spatial correlations, described by dozens of independently-measured parameters, can be quantitatively predicted from the structure of natural images. This suggests that efficient coding applies centrally, where it extends to higher-order sensory features and operates in a regime in which sensitivity increases with feature variability."}],"title":"Variance predicts salience in central sensory processing","publisher":"eLife Sciences Publications","publication_status":"published","month":"11","oa_version":"Published Version","year":"2014","file":[{"relation":"main_file","creator":"system","access_level":"open_access","file_name":"IST-2016-420-v1+1_e03722.full.pdf","date_updated":"2020-07-14T12:45:20Z","date_created":"2018-12-12T10:12:04Z","checksum":"766ac8999ac6e3364f10065a06024b8f","content_type":"application/pdf","file_id":"4922","file_size":5117086}],"oa":1,"file_date_updated":"2020-07-14T12:45:20Z","_id":"1886","doi":"10.7554/eLife.03722","pubrep_id":"420","day":"14","author":[{"last_name":"Hermundstad","full_name":"Hermundstad, Ann","first_name":"Ann"},{"full_name":"Briguglio, John","first_name":"John","last_name":"Briguglio"},{"last_name":"Conte","full_name":"Conte, Mary","first_name":"Mary"},{"last_name":"Victor","full_name":"Victor, Jonathan","first_name":"Jonathan"},{"last_name":"Balasubramanian","first_name":"Vijay","full_name":"Balasubramanian, Vijay"},{"first_name":"Gasper","full_name":"Tkacik, Gasper","last_name":"Tkacik","orcid":"0000-0002-6699-1455","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87"}],"has_accepted_license":"1","article_number":"e03722","status":"public","type":"journal_article","publist_id":"5209","department":[{"_id":"GaTk"}],"ddc":["570"],"tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"citation":{"chicago":"Hermundstad, Ann, John Briguglio, Mary Conte, Jonathan Victor, Vijay Balasubramanian, and Gašper Tkačik. “Variance Predicts Salience in Central Sensory Processing.” <i>ELife</i>. eLife Sciences Publications, 2014. <a href=\"https://doi.org/10.7554/eLife.03722\">https://doi.org/10.7554/eLife.03722</a>.","short":"A.
