The contribution

Longuet-Higgins considered memory for patterns that unfold over time, such as words and behavioral sequences. He proposed a temporal counterpart to holographic storage as a way to think about recognizing and recalling those patterns, extending the question of associative memory from static inputs to sequences.

What this does not establish

The letter presents a proposed model and a possible experimental implication. It does not establish that the brain uses a literal optical hologram or that the proposed mechanism is a complete account of recall.

Why this date?

The Nature letter was published on 6 January 1968. The publisher lists H. C. Longuet-Higgins and page 104; these are used instead of the differing initials and page range in the extracted Hopfield reference.
