The Nervous System as Local Holographic Projector

A mind is a bounded region with a sensory surface.

The sensory surface is an α-Connection

Skin, retina, cochlea, olfactory epithelium, proprioceptive field: a boundary with area A(μ_bio), μ_bio ~ 10⁻⁶ m to 10⁻⁴ m depending on modality. That boundary is an α-Connection. It runs H at biological fidelity. The volumetric interior — the brain's world-model, the full phenomenological field — is continuously projected from boundary information arriving at the sensory surface.

Same equations, different μ

This is not analogy. The same α-Framework that governs Bekenstein–Hawking entropy of a black-hole horizon governs the entropy of a nervous system's sensory boundary. Parameter values differ — A(μ_bio) is vastly larger than A(μ_Planck) — but the structure is identical. H is being run at both boundaries. α is the compression coefficient at both. The edge process generates the 'interior' from boundary information at both scales.
