Whole Mouse Brain Atlas
A collection of nine new papers (and one previously published) from BICCN researchers reports the first complete cell type atlas of a mammalian brain, with over 30 million cells profiled from the adult mouse brain using a combination of single-cell transcriptomic, epigenomic, and spatial transcriptomic approaches, identifying over 5,300 cell types in the entire mouse brain. These studies achieve brain-wide cross-modality integration between transcriptomic profiles and epigenomic, spatial, or connectional properties, as well as certain aspects of evolutionary conservation and divergence, and uncover multitudes of organizing principles of the extraordinary cell type diversity across the brain. Read more about the Whole Mouse Brain Atlas at BICCN, at the Allen Institute and at Nature.

Human and Non-Human Primate Cell Atlas
The human brain contains more than 100 billion cells, but exactly how these cells are organized into types and how these cell types differ between brain regions and species is an open question. BICCN researchers coordinately worked on a collection of studies defining and characterizing the underlying gene expression, gene regulatory, and morphoelectric features of cell types in the human and non-human primate (NHP) brain. Read more about the Human and Non-Human Primate Cell Atlas and this includes several packages of data now available at the Human Cell Atlas site as well.

Cell Types Knowledge Explorer
The Cell Types Knowledge Explorer is an interactive tool that aggregates rich, multimodal BICCN data at the level of individual cell types across mouse, human and marmoset. Developed in collaboration with the Allen Institute for Brain Science, the J. Craig Venter Institute, and the European Bioinformatics Institute, the Cell Types Explorer integrates the work of many BICCN laboratories and presents knowledge about cell types from the primary motor cortex in the form of intuitive data visualizations and text summaries. The Cell Types Explorer also serves as an entry point to the BICCN’s many freely available datasets and analysis tools and is powered by a data-driven ontology linking BICCN data to a well-established body of knowledge on neurobiology.

Cell Census of the Primary Motor Cortex
A major milestone in the effort to create a census of all brain cell types has been achieved. Dozens of research teams supported by the National Institutes of Health’s BRAIN Initiative Cell Census Network (BICCN) built a highly-detailed map of the motor cortex (MOp or M1). The resulting open-access data collection includes multimodal details of the cells found in the human, marmoset and mouse motor cortex including coordinated large-scale analyses of single-cell transcriptomes, chromatin accessibility, DNA methylomes, spatially resolved single-cell transcriptomes, morphological and electrophysiological properties, and cellular resolution input-output mapping, integrated through cross-modal computational analysis. The results establish a unified and mechanistic framework of neuronal cell type organization.

Controlled access to human sequencing data available
BICCN includes a growing number of datasets providing RNA sequence-level information in human brain, which is considered potentially identifiable. The consortium encourages use of tissue that is collected with the least restrictive consents, but datasets may consist of tissue collected under different patient consent conditions. Some datasets may be accessed without restrictions, including gene expression summarized as gene counts or otherwise aggregated to anonymize base sequences, and may be accessed directly from the NeMO data archive. Human sequence data collected under open access consent language may also be obtained directly from NeMO archive.
For human sequence level datasets collected under controlled access consent language, we announce a new process for data access. NeMO data archive has partnered with the NIMH Data Archive to provide a platform for application for and approval of human data access. Data access approvals will be managed at a dataset level by the NeMO data archive, and work is in progress to get each of the restricted access human datasets into the NDA platform. Please see detailed instructions here.

BICCN Highlighted as Collaborative Neuroscience "Method to Watch"
BICCN was highlighted in a recent "Methods to Watch" article from Nature Methods:
"Large-scale initiatives like these generate a wealth of data, resources and tools, and making these available to the community is bound to multiply their impact. We look forward to these efforts bearing fruit."
October 2019
Transcriptomics Explorer Launch
The Transcritpomics Explorer is a new tool that allows users to easily access cell-type information from mouse and human brains and to explore several custom-built visualizations of the data. Data supported by the U19 Zeng and U01 Lein BICCN grants is now available for visualization and analysis in the Transcriptomics Explorer.

BICCN Steering Committee Meeting
The fourth BICCN Steering Committee meeting was held at the Marriott Marquis Chicago on October 18, 2019 in advance of the Society for Neuroscience conference. Attendees heard progress updates from across the consortium, as well as presentations from the new BICCN grant awardees for 2019. Breakout sessions focused on topics including renewable antibody resources for proteomic phenotyping of the brain, consortium data infrastructure, and future planning for joint analysis opportunities.

BICCN Workshop
A workshop was held September 23-25, 2019 in Jackson Hole, WY to facilitate joint analysis of anatomical and morphological data from across the BICCN. Co-organized by Dr. Pavel Osten and the BCDC, the workshop brought together BICCN researchers and external experts in neuroanatomy to tackle the challenge of establishing standardized data analysis approaches.

BICCN Steering Committee Meeting & Workshop
The third BICCN Steering Committee meeting was held on NIH Campus in Bethesda, MD on April 10, 2019 in advance of the 5th annual BRAIN Initiative Investigators Meeting. Additionally, the BCDC lead coordination of a concurrent Data Mapping Workshop. In addition to moderated presentations and discussion from each major group within BICCN, the Steering Committee meeting included breakout sessions on: transgenic and viral tools; human and non-human primate progress and planning; and cloud-native pipelines.
The Data Mapping Workshop was a hands-on hack-a-thon style event to address the myriad challenges in accurate image modality definition, registration, and mapping, with the specific outcome of getting spatial features suitable to support inclusion of BICCN data into the Integrated Data Set.
