We held the fourth biennial Patricia Levy Zusman International Workshop on Neuroregeneration from March 7-10, 2023. There, 35 speakers presented on a wide array of topics and over twenty trainees exhibited their research during the poster presentation and poster blitz session. In addition, participants were encouraged to team up and brainstorm potential projects based on the ideas exchanged during the Zusman Workshop. AS a result, we were able to fund three teams whose projects focused on topics ranging from gut and brain health, double stranded DNA breaks, and spinal stimulation. These collaborations represent the heart of the Zusman Workshop. Funding for this workshop was made possible by the Patricia Levy Zusman Endowment and an NIH R13 grant.
