In the retina, many OFF ganglion cells exhibit responses to ON stimulation outside their receptive field center. However, disentangling the pathways and cell types contributing to these responses has been challenging with traditional experimental approaches. Here, we combined optogenetics, two-photon holographic stimulation, and multielectrode array recordings to identify the intermediate retinal cell types involved in this circuit. We found that the pathway consisting of rod bipolar cells and AII amacrine cells\u2014one of the primary relays of rod-driven signals under low-light conditions\u2014plays a key role in mediating this surround modulation. Specifically, crossover inhibition exploits the same amacrine cells responsible for surround suppression to disinhibit distant ganglion cells. This suggests that the retina repurposes existing circuits for surround modulation, optimizing resources through multifunctional inhibitory pathways.<\/jats:p>","DOI":"10.1073\/pnas.2532792123","type":"journal-article","created":{"date-parts":[[2026,8,24]],"date-time":"2026-08-24T19:02:04Z","timestamp":1787598124000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":1,"title":["The rod bipolar cell pathway contributes to surround responses in OFF retinal ganglion cells"],"prefix":"10.1073","volume":"123","author":[{"given":"Giulia","family":"Spampinato","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02en5vm52","id-type":"ROR","asserted-by":"publisher"}],"name":"Institut de la Vision, Sorbonne Universit\u00e9, INSERM, CNRS, 17 Rue Moreau","place":["Paris, France"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7368-4146","authenticated-orcid":false,"given":"Francesco","family":"Trapani","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02en5vm52","id-type":"ROR","asserted-by":"publisher"}],"name":"Institut de la Vision, Sorbonne Universit\u00e9, INSERM, CNRS, 17 Rue Moreau","place":["Paris, France"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4170-0754","authenticated-orcid":false,"given":"Victor","family":"Calbiague-Garcia","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02en5vm52","id-type":"ROR","asserted-by":"publisher"}],"name":"Institut de la Vision, Sorbonne Universit\u00e9, INSERM, CNRS, 17 Rue Moreau","place":["Paris, France"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Buffet","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02en5vm52","id-type":"ROR","asserted-by":"publisher"}],"name":"Institut de la Vision, Sorbonne Universit\u00e9, INSERM, CNRS, 17 Rue Moreau","place":["Paris, France"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7120-2481","authenticated-orcid":false,"given":"Elaine","family":"Orendorff","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/02en5vm52","id-type":"ROR","asserted-by":"publisher"}],"name":"Institut de la Vision, Sorbonne Universit\u00e9, INSERM, CNRS, 17 Rue Moreau","place":["Paris, France"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9983-3605","authenticated-orcid":false,"given":"B.
