Introduction
Biccn is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
The BRAIN Initiative Cell Census Network (BICCN) was a landmark collaborative effort funded by the NIH BRAIN Initiative that aimed to create a comprehensive cell type census of the mammalian brain. Launched in 2017 and completed in 2023, this consortium of over 30 institutions worldwide produced groundbreaking resources for understanding brain cell types across species, with profound implications for neurodegenerative disease research [@brain]. [@biccn2021]
Historical Context and Funding
The BICCN emerged from the recognition that understanding brain function requires knowing its fundamental building blocks - the diverse populations of [neurons](/entities/neurons) and glia that comprise neural circuits. The NIH BRAIN Initiative provided substantial funding to support this ambitious goal, with the Allen Institute serving as the lead coordinating institution. [@biccn2022]
The consortium brought together diverse expertise from:
Major research universities
National laboratories
Private research institutes
Technology companies
This collaborative approach enabled the integration of multiple modalities and the standardization necessary for creating a truly comprehensive cell census.
Consortium Structure and Institutions
Primary Institutions
The BICCN included numerous leading institutions:
