Abstract Neurotrauma, such as traumatic brain injury (TBI) and spinal cord injury (SCI), impacts over 60 million people per year globally with an estimated fiscal burden of $400 B/year. The National Neurotrauma Society (NNS) is committed to the promotion of neurotrauma research by enhancing communication, providing a forum for scientific exchange, and increasing national and international support for neurotrauma research and clinical advances. Every year, the society holds a symposium to meet this goal and provide a forum for researchers, clinicians, and trainees from around the world to meet and discuss the latest breakthroughs to improve the lives of individuals living with TBI and SCI related disability. The 41st Annual Neurotrauma Symposium, jointly sponsored by the NNS and the American Association of Neurological Surgeons/Congress of Neurological Surgeons (AANS/CNS) Joint Section on Neurotrauma and Critical Care will be held in San Francisco, CA, June 9 - June 14, 2024. This meeting will focus on showcasing the latest technological innovations in the neurotrauma field while celebrating the foundational biomedical research that continues to influence emerging knowledge and tools to improve neurotrauma research and clinical care. Broad objectives of the Symposium include: 1) updating attendees on current and timely topics in basic and clinical neurotrauma, 2) facilitating exchange of information among participants, 3) building new scientific collaborations, with a foundation in rigor, reproducibility, transparency, and translation, and 4) fostering active engagement of trainees and young investigators through our travel awards, poster competition, data blitz oral presentations, workshops and activities developed and supported by the Training, Education and Mentoring (TEAM) Committee. NIH funding for previous NNS Symposia has provided invaluable support for scientific sessions and for enhancing our ability to reach graduate students, postdoctoral researchers, residents, and young investigators. NIH support helps the NNS to provide travel awards to continue to promote trainee attendance, including underrepresented minorities (URM), women, and persons with disabilities. This application seeks funding to support 30 pre-and-postdoctoral trainees to present their ongoing work, attend scientific sessions, and to network with peers and faculty. Of the 30 trainees, at least 10 will meet the NIH definition of persons underrepresented in the biomedical workforce, including URMs, women, and individuals with disabilities as the society strives to continue to promote and retain diversity. In addition, we request support for programming for trainee and young investigator development sessions, sponsored by the TEAM Committee. Finally, we request support to continue our unique Local Scholars Program (LSP), successfully initiated in 2022, which provides support for undergraduate students who come from under- served backgrounds and who attend local universities ...
