Direct-application search returned a bounded negative: [[claim-no-amari-1977-neural-field-application-to-morphogenesis-found]] finds no application of Amari's 1977 model to developmental-biology morphogenesis (Cook et al. 2022 applications survey runs through neuroscience; zebrafish-skin Turing review cites no Amari), held [unverified] as absence-of-evidence. The reverse direction is affirmatively documented — [[claim-amari-1977-neural-field-paper-rooted-in-reaction-diffusion-morphogenesis-literature]] (Amari cites Turing 1952 + Maginu 1975) — and the Turing toolkit later reached the Amari-family formalism toward neuroscience, not morphogenesis ([[claim-ermentrout-cowan-1979-applied-neural-field-bifurcation-to-visual-hallucinations]], via [[claim-wilson-cowan-and-amari-neural-field-formulations-are-the-same-object]]). LEFT OPEN (not forced closed): unchecked leads remain — the formal Amari↔reaction-diffusion equivalence (arXiv:1504.07523), the login-gated Springer encyclopedia entry, Cartwright 2002 cortical folding, and Amari-type cortical-map self-organization."]

The vault's Amari-in-developmental-biology search
([[claim-no-amari-application-to-developmental-biology-found-pre-2016]]) was
scoped narrowly to Amari's **1972 associative-memory** architecture and found no
application to cell-fate / Waddington-landscape modeling. It deliberately did
**not** cover Amari's separate **1977 neural-field / lateral-inhibition
equations** — a distinct body of work with the mathematical structure (local
excitation, lateral inhibition, continuous spatial fields) that resembles
Turing-style reaction-diffusion patterning.

**The question:** was Amari's 1977 neural-field formalism ever applied to
reaction-diffusion morphogenesis or spatial pattern formation in developmental
biology? If so, it would open a second, structurally different Amari→biology
thread — spatial pattern formation rather than cell-fate attractors — with its
own priority/citation genealogy to trace.

**What would answer it:** a citation search for morphogenesis / pattern-formation
papers referencing Amari (1977, *Biological Cybernetics* 27:77–87, "Dynamics of
pattern formation in lateral-inhibition type neural fields") in a
developmental-biology (not neuroscience) context; and a check of whether the
Turing / reaction-diffusion modeling literature cites Amari's neural-field work
at all. Raised by the 2026-07-12 capture
(10-inbox/raw/2026-07-12-was-amaris-1972-associative-memory-model-ever-independently.md),
which flagged this as "a separate, unresearched thread."
