Examples of Neuroinformatics

Neuroinformatics is the convergence of neuroscience and informatics, focusing on the organization, analysis, and sharing of complex data related to the structure and function of the brain.

The Human Connectome Project (HCP): The HCP is an extensive effort to understand and map the neural pathways of the human brain. This project collects and shares data related to the brain’s connectivity, gathered using state-of-the-art neuroimaging techniques such as diffusion tensor imaging (DTI) and functional magnetic resonance imaging (fMRI). Researchers can access this detailed and organized database to develop new insights into the functioning of the human brain, and to explore connections between neural networks, behavior, and cognition.

The Allen Brain Atlas: This open-access resource provides highly detailed genome-level data that characterize gene expression levels and distribution in the mammalian brain, including humans and mice. The atlas presents information on thousands of individual genes, enabling researchers to identify genes that are specifically expressed in certain brain regions or cell types, and investigates how these genes contribute to brain structure, function, and disease. The Allen Brain Atlas has been instrumental in revealing gene expression patterns linked to various neurological disorders, such as autism and Alzheimer’s disease.

The Blue Brain Project: This ambitious project, led by the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, aims to create a digital reconstruction of the mammalian brain, with a primary focus on the neocortex. Neuroinformatics techniques are employed to integrate data from numerous sources, such as electrophysiological recordings, morphological analyses, and gene expression patterns. Simulations of the detailed digital model can help researchers understand the complex dynamics of neural circuits and their roles in cognition, perception, and behavior. Additionally, the Blue Brain Project contributes to the development of better tools and methods for analyzing and modeling large-scale brain data.
