How memory-related brain regions, such as the medial-temporal lobe, influence sensory cortex to support this process remains unclear. Here, we used two-photon calcium imaging of axonal projections from the perirhinal (PRh) cortex to the auditory cortex during learning and generalization of an auditory discrimination task. PRh input in the auditory cortex increased during learning and influenced performance in a categorization task. Chemogenetically silencing PRh input selectively disrupted the activity of auditory cortex layer 2\/3 pyramidal neurons, and PRh photoactivation drove behavior toward overgeneralization. These findings highlight PRh input as a key modulatory pathway that shapes cortical dynamics underlying auditory learning and memory-guided sensory perception.<\/jats:p>","DOI":"10.1126\/sciadv.aed4808","type":"journal-article","created":{"date-parts":[[2026,5,22]],"date-time":"2026-05-22T17:58:41Z","timestamp":1779472721000},"update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":0,"title":["Perirhinal input to auditory cortex supports memory-guided sensory perception"],"prefix":"10.1126","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9060-8500","authenticated-orcid":true,"given":"Luca","family":"Godenzini","sequence":"first","affiliation":[{"name":"Florey Institute of Neuroscience and Mental Health, Parkville, Victoria 3000, Australia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6032-6502","authenticated-orcid":true,"given":"Ann-Sofie","family":"Bjerre","sequence":"additional","affiliation":[{"name":"Florey Institute of Neuroscience and Mental Health, Parkville, Victoria 3000, Australia."},{"name":"School of Medicine, University of Tasmania, Hobart, Tasmania 7000, Australia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0913-4270","authenticated-orcid":true,"given":"Yi","family":"Hu","sequence":"additional","affiliation":[{"name":"Florey Institute of Neuroscience and Mental Health, Parkville, Victoria 3000, Australia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3676-657X","authenticated-orcid":true,"given":"Lucy M.","family":"Palmer","sequence":"additional","affiliation":[{"name":"Florey Institute of Neuroscience and Mental Health, Parkville, Victoria 3000, Australia."},{"name":"Florey Department of Neuroscience and Mental Health, University of Melbourne, Parkville, Victoria 3000, Australia."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"221","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-020-15534-z"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-025-62949-7"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-022-04724-y"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-023-42609-4"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2016.10.029"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.celrep.2022.111394"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tins.2018.08.011"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1038\/ncomms13217"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cub.2019.03.003"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-021-03452-z"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-025-59342-9"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2018.10.002"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2019.06.004"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1038\/nn.4061"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2023.09.041"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tins.2022.11.001"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-021-24754-w"},{"key":"e_1_3_2_19_2","doi-asserted-by":"crossref","unstructured":"G.
