Federal Project Grant Award Summary

The Allen Institute received a $1.88 million Project Grant from the National Institute of Mental Health (NIMH) under the Mental Health Research Grants program (CFDA 93.242), awarded on March 13, 2026, with completion targeted for December 31, 2028. This award supports the creation of a refined, high-resolution cellular atlas of the brainstem using integrated single-cell and spatial transcriptomic profiling methodologies. The project deliverables include comprehensive characterization of brainstem cell types through single-cell transcriptomic analysis, spatial transcriptomic mapping, and functional projection pattern analysis to resolve the complex cellular heterogeneity and anatomical organization of this critical brain region. This research directly advances NIMH's mission to transform understanding of mental illnesses through basic neuroscience by establishing fundamental knowledge of brainstem neural circuits that regulate essential bodily functions including heart rate, blood pressure, and digestion—processes integral to mental health and homeostasis.

The Allen Institute, a non-profit neuroscience research organization headquartered in Seattle, will deliver open-access research data and tools that enable future investigations into brainstem function in both normal physiology and disease contexts. As an established recipient of substantial federal research funding from NIMH, the National Institute of Neurological Disorders and Stroke, and other NIH institutes, the Allen Institute is positioned to generate the sophisticated scientific outputs and collaborative research infrastructure characteristic of its prior foundational neuroscience work. The project supports the broader Mental Health Research Grants program objective of funding hypothesis-driven, translational investigations into the etiology and underlying mechanisms of mental illnesses through rigorous basic science inquiry.
