This field is referred to as the \"nonclassical receptive field\" (nCRF). It has been reported in monkey that the extent of CRF and/or nCRF of V1 neurons is not fixed but varies with stimulus contrast. We reexamined the contrast dependence of V1 neurons in cat to determine whether this differs from previous studies in macaque. By fitting the spatial summation curves obtained at different contrasts with a difference of Gaussians model, we estimated quantitatively the effect of contrast on the spatial extent of the CRF and nCRF as well as the strength of surround suppression. Our results showed that both the CRF and nCRF expanded at low contrast, but the expansion is more marked for the CRF than for the nCRF. Although the effect of contrast on surround suppression was varied, the overall suppression increased significantly at high contrast. Moreover, the contrast-dependent change in the extent of CRF is independent of the change in suppression strength. Overall, our results in cat are in agreement with those obtained in macaque money.","is_dataset_classified":null,"base_score":3.332204510175204,"endowment":3.332204510175204,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"22302117","pmcid":null,"openalex_id":"https://openalex.org/W2119704728","authors":[],"funders":[],"total_grants":0,"fwci":1.543,"citation_percentile":0.81576598,"influential_citations":0,"citation_trend":[{"year":2014,"count":4},{"year":2015,"count":8},{"year":2016,"count":2},{"year":2018,"count":1},{"year":2019,"count":1},{"year":2020,"count":2},{"year":2021,"count":1},{"year":2022,"count":3},{"year":2023,"count":2},{"year":2024,"count":2},{"year":2026,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://academic.oup.com/cercor/article-pdf/23/2/283/795813/bhs012.pdf","host_type":"publisher"},{"url":"https://doi.org/10.1093/cercor/bhs012","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/22302117","host_type":"repository"}],"fields_of_study":["Visual perception and processing mechanisms","Neural dynamics and brain function","Retinal Development and Disorders"],"mesh_terms":["Action Potentials","Animals","Cats","Neurons","Visual Cortex","Contrast Sensitivity","Single-Cell Analysis"],"keywords":["Receptive field","Macaque","Surround suppression","Contrast (vision)","Visual cortex","Neuroscience","Stimulus (psychology)","Summation","Inhibitory postsynaptic potential","Excitatory postsynaptic potential","Psychology","Physics","Visual perception","Optics","Cognitive psychology","Stimulation","Perception"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-16T14:36:41.591725Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
