Identity-Preserving Sensorimotor and Neuromodulatory Embodiment Subsystems for Artificial Consciousness Transfer Substrates, and Methods for Determining Embodiment Requirements Using a Hierarchical Identity Metric

A method and apparatus for preserving personal identity during consciousness transfer from a biological brain to an artificial substrate embedded in a robotic or prosthetic body. A hierarchical identity metric derived from the brain's coupling matrix is used to determine which sensorimotor and neuromodulatory subsystems of the biological body are identity-load-bearing for a given individual. The artificial body is equipped with functional equivalents of each identity-load-bearing subsystem, comprising sensory transducer arrays mapped to the coupling matrix's cortical representation, neuromodulatory emulation layers reproducing hormonal and neurotransmitter cascade effects on coupling gains, and actuators closing sensorimotor feedback loops. A real-time monitor verifies identity preservation throughout transfer and ongoing operation. The invention enables consciousness transfer to bodies of arbitrary morphology while maintaining personal identity within a specified tolerance. The invention concerns the target body and its embodiment subsystems; the consciousness transfer mechanism itself is outside the scope of this disclosure.
