NIH Highlighted Topic: Neural Exposome Factors that Affect Brain Health and Neurological Disorders
Below is a brief summary. Please check the full solicitation before applying (link in resources section).
Executive Summary:
The National Institutes of Health (NIH) is seeking innovative research proposals through the SBIR Program focused on understanding how environmental, behavioral, biological, and psychosocial exposures influence brain health and neurological disease across the lifespan. NIH is particularly interested in technologies and research platforms that investigate the “Neural Exposome” — the cumulative interaction of genetic and nonheritable factors affecting neurological function, disease progression, and long-term brain health.
While genetics have provided major insights into neurological disorders, many conditions cannot be explained by genetics alone. NIH is encouraging interdisciplinary projects that examine how environmental toxins, stress, sleep, microbiome activity, metabolism, diet, substance use, epigenetic changes, and other exposome factors interact with biological systems to influence neurological outcomes. Companies developing AI-enabled analytics tools, biomarkers, computational models, organoids, neuroimaging platforms, environmental health technologies, digital health systems, or advanced neuroscience research tools may be strong candidates for funding.
NIH is especially interested in projects involving longitudinal cohort analysis, gene-environment interaction modeling, exposome biomarker discovery, human-relevant disease models, organoid systems, computational neuroscience, and preventative intervention strategies. Research focused on women’s health, aging, substance use, neuroimmune interactions, and multi-organ system relationships impacting brain health is also encouraged.
Through the NIH SBIR Program, U.S. small businesses may apply for up to $323,090 in Phase I funding and up to $2,153,927 in Phase II funding to support research, development, validation, and commercialization activities. Applications are accepted on January 5th, April 5th, and September 5th annually, with funding typically beginning approximately 9 months after submission.
This highlighted topic is supported primarily by the National Institute of Neurological Disorders and Stroke (NINDS), the National Heart, Lung, and Blood Institute (NHLBI), the National Institute on Drug Abuse (NIDA), the National Institute on Aging (NIA), the National Eye Institute (NEI), and the Office of Research on Women’s Health (ORWH), all of which may give special consideration to high-impact applications advancing environmental neuroscience, exposome science, neurological disease prevention, and translational brain health technologies.
How much funding would I receive?
Awards provide up to $323,090 for Phase I projects (up to 2 years) and $2,153,927 for Phase II projects (up to 3 years). Some topics approved by NIH may exceed these limits. Fast-Track and Phase IIB (follow-on) options allow continuous or extended funding beyond Phase II.
What could I use the funding for?
Funding may support the research, development, validation, and commercialization of technologies and research platforms focused on neural exposome science, brain health, and neurological disease prevention.
Eligible activities may include:
AI and machine learning platforms analyzing gene-environment interactions and neurological risk factors
Biomarker discovery technologies for detecting neurological effects of environmental and behavioral exposures
Longitudinal cohort studies integrating exposome and neurological health data
Computational models evaluating composite environmental impacts on brain function and disease progression
Organoid systems, in vitro models, and human-relevant neuroscience platforms for exposome research
Neuroimaging and sensor technologies for studying environmental effects on the nervous system
Digital health tools monitoring sleep, stress, substance use, environmental exposures, and neurological outcomes
Research into neuroimmune interactions and multi-organ system effects on brain health
Studies evaluating effects of toxins, microbiome changes, metabolism, diet, and psychosocial stressors on neurological function
Precision medicine approaches integrating genomic, behavioral, and environmental health data
Women’s health-focused research investigating hormonal, environmental, and neurological interactions across the lifespan
Substance use and addiction-related exposome research
Aging-related neurological health studies and preventative intervention strategies
Development of preventative therapeutics and intervention technologies targeting modifiable neurological risk factors
Validation studies, translational research, prototype development, and regulatory preparation activities
Commercialization planning and scale-up activities for brain health and exposome-related technologies
Funding may also support personnel, laboratory testing, software development, computational infrastructure, prototype fabrication, data integration systems, intellectual property protection, commercialization strategy development, and other research and development activities necessary to advance a commercially viable solution aligned with NIH priorities.
Are there any additional benefits I would receive?
Beyond the formal funding award, awardees gain several strategic advantages:
Government Validation and Credibility:
Being selected for an NIH-backed SBIR grant signals technical excellence and alignment with national health and biomedical priorities. This validation builds investor and partner confidence.Enhanced Visibility and Market Recognition:
Awardees are featured in NIH and HHS announcements, helping attract partnerships, media attention, and future contracting opportunities.Access to the Federal Innovation Ecosystem:
Recipients join a national network of researchers and agencies advancing life science innovation, often opening doors to collaborations with NIH laboratories and federal health programs.Stronger Commercial and Exit Potential:
By maturing technology through nondilutive funding, companies strengthen valuation, de-risk commercialization, and increase attractiveness for acquisition or follow-on private investment.
What is the timeline to apply and when would I receive funding?
Applications are accepted each year on January 5th, April 5th, and September 5th. Funding is received approximately 9 months after submission.
Where does this funding come from?
Funding comes from the U.S. Department of Health and Human Services, with statutory set-asides requiring NIH, CDC, and FDA to devote portions of their extramural R&D budgets (3.2% for SBIR, 0.45% for STTR) to support small business innovation.
Who is eligible to apply?
Applicants must be U.S. small business concerns (SBCs) that:
Are organized for profit with a U.S. place of business.
Have ≤ 500 employees including affiliates.
Are > 50% owned by U.S. citizens or permanent residents, qualifying U.S. entities, or combinations thereof.
What companies and projects are likely to win?
Projects that demonstrate:
A clear unmet medical or public-health need,
Strong scientific rationale and feasibility,
High commercialization potential, supported by a realistic market and regulatory strategy, and
Alignment with an NIH Institute’s or CDC/FDA Center’s specific research mission (e.g., infectious disease, digital health, diagnostics, therapeutics, or data analytics).
Competitive applicants often have an early prototype, preliminary data, and a defined path to market adoption.
Are there any restrictions I should know about?
Companies must complete multiple federal registrations (SAM.gov, Grants.gov, eRA Commons, SBA Company Registry) before applying.
Foreign entities are not eligible.
Disclosure of foreign affiliations and compliance with national security screening are mandatory. Currently we do not recommend any sort of foreign affiliation.
How long will it take me to prepare an application?
For a first-time applicant, preparing a competitive submission will likely take 120–200 hours in total.
