Progress Toward Defining Innovations
Optical Noninvasive Brain–Computer Interface Development: Challenges and Opportunities
The Defense Advanced Research Projects Agency’s Revolutionizing Prosthetics program demonstrated the potential for neural interface technologies, enabling patients to control and feel a prosthetic arm and hand, and even pilot an aircraft in simulation. These landmark achievements required invasive, chronically implanted penetrating electrode arrays, which are fundamentally incompatible with applications for the able-bodied warfighter or for long-term clinical applications. Noninvasive neural recording approaches have not been as effective, suffering from severe limitations in temporal and spatial resolution, signal-to-noise ratio, depth penetration, portability, and cost. To help close these gaps, researchers at the Johns Hopkins University Applied Physics Laboratory (APL) are exploring optical techniques that record correlates of neural activity through either hemodynamic signatures or neural tissue motion as represented by the fast optical signal. Although these two signatures differ in terms of spatiotemporal resolution and depth at which the neural activity is recorded, they provide a path to realizing a portable, low-cost, high-performance brain–computer interface. If successful, this work will help usher in a new era of computing at the speed of thought.

Special Features
APL’s New Campus Master Plan
The Johns Hopkins University Applied Physics Laboratory (APL) has had a long history of campus land planning, beginning with its purchase of a 290-acre property in Laurel, Maryland in 1952. With the APL campus currently encompassing nearly 500 acres including owned and leased properties, the Laboratory faces several challenges in planning for future development. First it is hitting ceilings on available land on which to build. The continued tightening of government regulations, including environmental and zoning requirements, limits APL’s property development potential to approximately 250 acres. Second is the increasing complexity of the facilities APL requires today. Facilities often need to be uniquely tailored to meet specific sponsor or program needs, limiting their ability to be repurposed later. Third is the continued land planning efforts necessary to address the ever-evolving workplace requirements and needs of APL staff. Beyond simply indicating where staff are to work, development plans must fully consider how staff need to work. In response to these challenges, the Laboratory undertook a new master planning effort for its campus. The subsequent new Campus Master Plan, developed during the Campus Development Process, is grounded in the Laboratory’s core values and addresses the evolving aspects of technology, sponsor needs, environmental and regulatory requirements, and workplace culture and effectiveness.
