Abstract

This paper proposes a cautious, developmentally grounded hypothesis about the functional role of the rose‑hip neuron, a recently identified and potentially human‑specific inhibitory interneuron in cortical layer 1. Drawing on its distinctive morphology, selective targeting of distal pyramidal dendrites, and unique genetic profile, the paper suggests that the rose‑hip neuron may contribute to the fine‑grained gating of relational integration in the human cortex. This interpretation does not claim a definitive function; instead, it offers a coherent framework that links existing empirical findings with a structural account of how organized meaning emerges. The paper outlines testable predictions concerning developmental timing, compartment‑specific modulation, context‑dependent activation, and possible human‑specific contributions, providing a conceptual foundation for future empirical work.
