# DARPA N3 acoustic and ultrasound branch **Aliases:** DARPA N3 acoustic/ultrasound branch **Entity class:** Organization or institution **Collections:** [[collections/Neurotech|Neurotech]] · [[collections/Consciousness Continuity|Consciousness Continuity]] ## Definition **DARPA N3 acoustic and ultrasound branch** is an organization or institution. The technical comparison identifies a convergence: [[wiki/Merge Labs|Merge Labs]] provides a technical overlay for **DARPA N3 acoustic and ultrasound branch**. N3 explored focused ultrasound. acousto-optical. and acousto-magnetic routes years before Merge’s commercial stack. The entry centers on the organization's documented work, partners, users, and institutional lineage, so its own role remains distinct from the roles of adjacent programs and technologies. ## Relationships <!-- BEGIN HUMANIZED RELATIONSHIPS 2026-09-11 --> This entry is routed through [[collections/Neurotech|Neurotech]] and [[collections/Consciousness Continuity|Consciousness Continuity]]. Its source context is developed in [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]]. Status-qualified source edges are preserved in the terminal Research Edges section. ### Additional Documented Relationships - The technical comparison identifies a convergence: [[wiki/Merge Labs|Merge Labs]] provides a technical overlay for **DARPA N3 acoustic and ultrasound branch**.
