To articulate this theory, we describe stimulus-evoked activity of a neural population based on the maximum entropy principle with constraints on two types of overlapping activities, one that is controlled by stimulus conditions and the other, termed internal activity, that is regulated internally in an organism. We demonstrate that modulation of the internal activity rea","authors_text":"Hideaki Shimazaki","cross_cats":["physics.bio-ph","physics.data-an"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.NC","submitted_at":"2015-12-24T16:40:01Z","title":"Neurons as an Information-theoretic Engine"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1512.07855","kind":"arxiv","version":2},"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":"sha256:1267c6a16785bbbca4d46b5261ce01926c4d8c11be3dc7342a78465cdcb4aa5f","target":"record","created_at":"2026-05-18T00:27:10Z","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":"3c83500a95503f061347e12ef124eb986a59f1111c7a9a49ec42258f3d94d2aa","cross_cats_sorted":["physics.bio-ph","physics.data-an"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.NC","submitted_at":"2015-12-24T16:40:01Z","title_canon_sha256":"6336f053e9800f44d1a2ea7921238fdd13b0143d65c755c11eb48240620cdd43"},"schema_version":"1.0","source":{"id":"1512.07855","kind":"arxiv","version":2}},"canonical_sha256":"cb53a890cdef90a6712a27868f1dd33f6ce53eb5d61bc6aa63a4f2ecf7de48c2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cb53a890cdef90a6712a27868f1dd33f6ce53eb5d61bc6aa63a4f2ecf7de48c2","first_computed_at":"2026-05-18T00:27:10.205163Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:27:10.205163Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"x3OT00D1Oy7b7Y24J1dtezLHTbksTP4Au7Clzre/fJm5/sScSELAXBwrPaAfmghtfwJDQMZQUWW/gonCFUpEDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:27:10.205737Z","signed_message":"canonical_sha256_bytes"},"source_id":"1512.07855","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1267c6a16785bbbca4d46b5261ce01926c4d8c11be3dc7342a78465cdcb4aa5f","sha256:63299ecaf60da6d5bd52963da202e84a65764ce0172053d0baa3a653a9cb56c9"],"state_sha256":"94fef8e32083bef661482eeb07fd1a55b73f3c04f2a430adac364b4de317abad"}
