We find that blowfly photoreceptors, up to frequencies of 50-100 Hz and photon capture rates of up to about 3*10^5/s, operate well within an order of magnitude from ideal photon counters. Photoreceptors signals are transmitted to LMCs through an array of chemical synapses. We quantify a lower bound on LMC reliability, which in turn provides a lower bound on synaptic vesicle release rate, assuming P","authors_text":"Rob de Ruyter van Steveninck, William Bialek","cross_cats":["q-bio.NC"],"headline":"","license":"","primary_cat":"physics.bio-ph","submitted_at":"2002-02-05T06:47:32Z","title":"Timing and Counting Precision in the Blowfly Visual System"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"physics/0202014","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:ddfaa414ae4a55129a8a64f62f58f7f0ccf6ad5ad38ea86d9eaed68bb038eadb","target":"record","created_at":"2026-07-04T14:43:35Z","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":"460628536beb557d3df104cf47c9831cc1e053094c2217159bedb867e5ff29ff","cross_cats_sorted":["q-bio.NC"],"license":"","primary_cat":"physics.bio-ph","submitted_at":"2002-02-05T06:47:32Z","title_canon_sha256":"79a0736154a1b0ab74223d21fa6844eb90820c620452439669e51315cf365bc7"},"schema_version":"1.0","source":{"id":"physics/0202014","kind":"arxiv","version":1}},"canonical_sha256":"75064ce9d5225f2f84659ccfd88ecd334a072b47368e5ff460858882b0aa7ce9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"75064ce9d5225f2f84659ccfd88ecd334a072b47368e5ff460858882b0aa7ce9","first_computed_at":"2026-07-04T14:43:35.143809Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T14:43:35.143809Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"B8b2zgDtf7H0qVHbKJHqi207VYa3OPg0vTDFgPgN42QjGYshAWWDrHmde2p4H3tNzN0fLu5D5fkB0ohLfMi4Dg==","signature_status":"signed_v1","signed_at":"2026-07-04T14:43:35.144193Z","signed_message":"canonical_sha256_bytes"},"source_id":"physics/0202014","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ddfaa414ae4a55129a8a64f62f58f7f0ccf6ad5ad38ea86d9eaed68bb038eadb","sha256:cba140848091920d368b3126cc80ab51565e8143a4fefc08b426c49c8be70d04"],"state_sha256":"e60328a623c1505382062f42a0456b54ccc9bfa69e075651bee06375e432a12c"}
