The National Institutes of Health (NIH) is offering the Imaging - Science Track Award for Research Transition (I/START), a federal grant aimed at supporting small research projects in neuroimaging methodologies. This funding opportunity encourages both new and established investigators to conduct "proof of concept" studies that advance understanding of central nervous system dysfunction related to substance use disorders, without the need for preliminary data. Eligible applicants include a wide range of organizations such as higher education institutions, nonprofits, and tribal governments, with a maximum funding amount of $150,000 available for one year. Applications are due by January 8, 2025, and interested parties can find more information and application details at the NIH grants website or contact the NIH OER Webmaster at grantsinfo@nih.gov.
