Six years and 32 million cells later, scientists have created the first full cellular map of a mammalian brain. In a set of 10 papers in Nature today, a network of researchers unveiled an atlas cataloging the location and type of every cell in the adult mouse brain. This relationship underscores how location shapes function, offering clues into the evolutionary history and intricate interactions of different brain regions. While the ancient ventral part features a mosaic of interrelated cells, the more recent dorsal part contains fewer but highly divergent cell types. This distinction could be a key to deciphering how different brain regions evolved unique roles, for example, the ventral part for basic survival and the dorsal part for adaptation, Zeng said. The atlas also uncovered how brain cells talk to each other via a diverse cast of signaling molecules, which carry messages from cell to cell. That diversity enables complex interactions between different cell types.

The Allen mouse brain atlas is a comprehensive digital resource that provides detailed information on the structure and function of the mouse brain. The Allen Mouse Brain Common Coordinate Framework is the backbone of spatially-focused workflows and tools that support spatial registration of new data to the atlas framework, semi-automatic analyses using the brain region hierarchy and delineations, and visualisation of extracted data in 3D. The atlas is incorporated in the QuickNII tool for spatial registration of serial 2D images, and employed in the QUINT workflow for extracting and quantifying labelled objects from images registered to the atlas. Originally built as a backend service for the interactive atlas viewer siibra-explorer, the API has been documented for connecting the brain atlases to other applications and web services.

Our focus on neuroscience began with the launch of the Allen Institute for Brain Science in , which led to the creation of the widely-used Allen Brain Atlases. This division has recently begun a new year phase focused on multimodal characterization of brain cell types. In , we launched the Allen Institute for Neural Dynamics , a new neuroscience division dedicated to understanding how dynamic neuronal signals across the entire brain perform fundamental computations and drive flexible behaviors. The Allen Institute practices open science, releasing our data, analysis tools, and other scientific resources publicly here at brain-map. We aim to accelerate research and education efforts across the world by lowering barriers to access and supporting collaboration.

The Allen Institute for Brain Science was established in with a goal to accelerate neuroscience research worldwide with the release of large-scale, publicly available atlases of the brain. Our research teams continue to conduct investigations into the inner workings of the brain to understand its components and how they come together to drive behavior and make us who we are. One of our core principles is Open Science: We publicly share all the data, products, and findings from our work. Here on brain-map. The potential uses of Allen Institute for Brain Science resources, on their own or in combination with your own data, are endless. Read below to learn about our major datasets and tools to determine which are the best fit for your needs.

Prior knowledge informed us that the transcription factor master plan is played out during development to generate cell types and brain regions in a stepwise manner. Each neuronal cluster is assigned to the most dominant region. Hnasko, T. Madisen, L. Maturation trajectories in dentate gyrus DG b , inner olfactory bulb c , and outer olfactory bulb d are highlighted. Nature thanks Seth Blackshaw and the other, anonymous, reviewer s for their contribution to the peer review of this work. Bar graphs on the top show number of cells per subclass, Gini coefficient and class assignment. Bar graphs on the left show the broad CCFv3 regions, proportion of neuronal versus glial cells per region of interest ROI , and proportion of neurotransmitter types per ROI. Moonsman, S. A comparison of gene regulatory programs across different species , including humans. The Allen Institute for Brain Science uses a unique approach to generate data, tools and knowledge for researchers to explore the biological complexity of the mammalian brain.
