The National Institutes of Health (NIH) is offering a federal grant opportunity titled "Neural Ensembles & Used Substances (NExUS) Collaboratory," aimed at building a multimodal inventory of cell ensembles that encode the effects of addictive substances. This initiative seeks to advance the understanding of neural cell populations and their alterations due to substance-related experiences, with specific goals including the collection of granular datasets, integration of various data modalities, and the development of analytical tools for ensemble activity. The grant, which has a funding ceiling of $700,000 and anticipates awarding four grants, is open to a diverse range of applicants, including tribal governments, federal agencies, and non-domestic entities. Interested parties can reach out to Olivier Berton at olivier.berton@nih.gov or by phone at 301-827-7771 for further information, with applications expected to be submitted by June 2, 2026, and project start dates anticipated for April 1, 2027.
