Was Amari's 1977 neural-field / lateral-inhibition work ever applied to Turing-style reaction-diffusion morphogenesis?

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."
