Claim and evidence Close ×
Bray (Journal of Theoretical Biology, 22 March 1990) describes a procedure by which a parallel distributed processing (PDP) network could simulate a cell signalling pathway, and states that the analogy with PDP networks shows how living cells can recognise combinations of environmental influences.

Date 1990-03-22 · publication Records dated 1990 → Role Earliest located Register (kind of text) Nonfiction Scope of the passage A proposed network model of a signalling pathway, not of a whole cell. Scope and limits The record documents what this text states, in its register; it is not evidence that the proposition is true and implies no influence on or from any other text. Read in the abstract as PubMed reproduces it; the publisher’s text was not read. A proposed model of one signalling pathway, not a simulation of a whole cell; the criterion covers a cell’s responses, and the cross-family check applied its “machine-learning or other AI model” to a PDP (neural) network. The research pack had headlined a 2018 text; this one holds the role from the admission (maintainer decision of 2026-10-30). Earliest located for this proposition among the texts found by the searches described under “How we searched”; not a claim that no earlier text exists.

An exploratory record that no editor has accepted. This status does not say whether a person has read any linked passage. Each evidence record above shows how it was checked.
Relation. A passage of the document meets the proposition’s criterion. The record documents what the text states, in its register (fiction and satire are labelled); it is not evidence that the proposition is true and implies no influence on or from another text.
Date. Date of the journal issue in the PubMed citation (J Theor Biol 1990 Mar 22;143(2):215–231).
