Neuroscience Needs Behavioral “Wind Tunnels” for Real-Life Translation

Le résumé fourni par la source

Neuroscience has advanced rapidly over the past century by applying reductionist methods to dissect brain function at molecular, cellular, and circuit levels, primarily in animal models. While this approach has generated extraordinary insights, the field now faces an epistemological bottleneck: efforts to build holistic models of human cognition from fragmented reductionist data are failing to capture the complexity of real-world brain function. Current translational pathways are dominated by a clinical mission-using dysfunction to model normal function-which limits ecological validity and reinforces blind spots. We argue that neuroscience must broaden its ontological mission beyond treatment of DSM-defined disorders to include functional misalignments and productivity in everyday life, encompassing education, workplaces, and social contexts. To achieve this, we propose the concept of behavioral "wind tunnels," an analogy to the facilities that transformed aerodynamics. Like wind tunnels, such environments would provide a controlled yet naturalistic middle ground between laboratory reductionism and the uncontrolled complexity of real-world settings. They would enable scalable capture of cognitive traits and states across wide populations, long time horizons, and multiple functional dimensions, yielding ecologically valid feedback loops essential for both theory and application. Embedding neuroscience into real-world contexts would align the field with pressing societal needs-optimizing human skills in an AI-disrupted economy, fostering resilience to global crises, and advancing brain health as an economic and societal asset. Just as wind tunnels transformed aviation from theory to reliable practice, neuroscience must now adopt analogous infrastructures to realize its full potential for humanity.
