Characterizing cellular diversity at different levels of biological organization and across data modalities is a prerequisite to understanding the function of cell types in the brain. Classification of neurons is also essential to manipulate cell types in controlled ways and to understand their variation and vulnerability in brain disorders. The BRAIN Initiative Cell Census Network (BICCN) is an integrated network of data-generating centers, data archives, and data standards developers, with the goal of systematic multimodal brain cell type profiling and characterization. Emphasis of the BICCN is on the whole mouse brain with demonstration of prototype feasibility for human and nonhuman primate (NHP) brains. Here, we provide a guide to the cellular and spatial approaches employed by the BICCN, and to accessing and using these data and extensive resources, including the BRAIN Cell Data Center (BCDC), which serves to manage and integrate data across the ecosystem. We illustrate the power of the BICCN data ecosystem through vignettes highlighting several BICCN analysis and visualization tools. Finally, we present emerging standards that have been developed or adopted toward Findable, Accessible, Interoperable, and Reusable (FAIR) neuroscience. The combined BICCN ecosystem provides a comprehensive resource for the exploration and analysis of cell types in the brain.

Radical surgery remains the primary treatment option for gall bladder cancer (GBC). Margin-negative liver resection is a critical component of radical cholecystectomy. Anatomical segment IVb and V resection is preferred in primary GBC with liver infiltration and incidental GBC patients with puckering of gall bladder (GB) bed. Despite the initial scepticism, minimally invasive radical cholecystectomy is recommended as a treatment option in selected GBC patients. However, anatomical Segment IVb and V resection using the minimally invasive approach is scarcely reported. The standardised technique of robotic (daVinci®XiTM) anatomical Segment IVb and V liver resection guided by indocyanine green fluorescence is described here. The systematic fluorescence-guided anatomical resection described in this report could facilitate minimally invasive Segment IVb and V resection with radical lymphadenectomy in selected patients with GBC.
