A team of global scientists has successfully charted the genetic, cellular, and structural composition of both human and nonhuman primate brains. Supported by the National Institutes of Health’s Brain Research Through Advancing Innovative Neurotechnologies® Initiative, commonly referred to as The BRAIN Initiative®, this analysis enhances our comprehension of brain function at the cellular level. This advanced understanding could eventually lead to the development of precision therapeutics for various brain and mental disorders. The research results can be found in 24 papers spread across journals like Science, Science Advances, and Science Translational Medicine.
Joshua A. Gordon, M.D., Ph.D., director of the National Institute of Mental Health commented, “Mapping the brain’s cellular landscape is a critical step toward understanding how this vital organ works in health and disease.” He further added, “These new detailed cell atlases of the human brain and the nonhuman primate brain offer a foundation for designing new therapies that can target the specific brain cells and circuits involved in brain disorders.”
The extensive collection from the BRAIN Initiative Cell Census Network (BICCN) elaborates on the intricate variety of cells in the brains of both humans and nonhuman primates. The research touched upon various topics, such as:
- The unveiling of the first cellular atlas of the adult human brain, discussing the transcriptional and epigenomic aspects. This looks at the entire set of gene readouts in cells and how the DNA and chromosomes of a cell undergo chemical modifications affecting gene expression.
- An analysis comparing cellular and molecular properties across the brains of different primates, including chimpanzees, gorillas, macaques, and marmosets. The results showcased the subtle genetic shifts that enabled the human brain to have superior adaptability, learning, and change capabilities.
- A deep dive into marmoset brain regions unveiled how cell properties in the adult brain can be traced back to the developmental stages. This discovery might reshape our understanding of brain development and function across different life stages.
- A study on the outermost layer of the neocortex, responsible for cognitive functions and language, displayed distinct differences between human and mouse brains. These differences might indicate an evolutionary evolution in humans to handle intricate brain circuits.
John Ngai, Ph.D., director of the NIH BRAIN Initiative, expressed his admiration, stating, “This suite of studies represents a landmark achievement in illuminating the complexity of the human brain at the cellular level. The scientific collaborations forged through BICCN are propelling the field forward at an exponential pace; the progress—and possibilities—have been simply breathtaking.”
This extensive research is not just a milestone in understanding brain cells but also sets the groundwork for other large-scale projects under The BRAIN Initiative, aiming to overhaul neuroscience research by addressing core principles controlling behavior and innovating treatments for brain disorders.
