In the songbird, the timing of a highly stereotyped song motif is attributed to the cortical nucleus HVC, and to feedback to HVC from downstream nuclei in the song motor pathway. Control of the acoustic structure appears to be shared by various structures, whose functional connectivity is largely unknown. Currently there exists no model for functional synaptic architecture that links HVC to song output in a manner consistent with experiments. Here we build on a previous model of HVC in which a","authors_text":"Eve Armstrong","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.NC","submitted_at":"2018-01-18T20:27:21Z","title":"Computational model of avian nervous system nuclei governing learned song"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1801.06226","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:09b6cca9835effeeff3616bf6b9c0318ed34b4cd96d452d3e690cf7583d5aeff","target":"record","created_at":"2026-05-18T00:25:33Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"b627d5903a19d83a2ca1c0606dad8f7281af8827a14458424d2dfe6ee12b7ac1","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.NC","submitted_at":"2018-01-18T20:27:21Z","title_canon_sha256":"5bd608d92e8ddb98c9b07313083988089312b9f040c93dbc031938891fdf125e"},"schema_version":"1.0","source":{"id":"1801.06226","kind":"arxiv","version":1}},"canonical_sha256":"cbcd1204f3485c6489fe08966dcee18062c7841658fec86a3b857a700471d4b0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cbcd1204f3485c6489fe08966dcee18062c7841658fec86a3b857a700471d4b0","first_computed_at":"2026-05-18T00:25:33.107129Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:25:33.107129Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HgtN8sv26b8oPVKJTxxkKE6THP1U51i1RuNHUejJpysBIX9vx59dlU0krtHGU/iRrVApcKSdsAAJ9hHPzGKPCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:25:33.107857Z","signed_message":"canonical_sha256_bytes"},"source_id":"1801.06226","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:09b6cca9835effeeff3616bf6b9c0318ed34b4cd96d452d3e690cf7583d5aeff","sha256:940cd236072a442852349ab34f96d8cfdd34927a8bca9b72eddd236251d3607d"],"state_sha256":"29b64ce32c6faf8bc021f284fe3d6350d3b44f0ae83555cd66e0affc116e6bdb"}
