Defining cell types

Recent articles

This series explores how new high-throughput technologies are changing the way we define brain-cell types—and the challenges that remain.

A playful cellular map features top-down and bottom-up views of the human brain arranged side-by-side as if they were the earth’s two hemispheres in an old-fashioned map of the world. The brains are colored to suggest land masses and bodies of water.

Knowledge graphs can help make sense of the flood of cell-type data

These tools, widely used in the technology industry, could provide a foundation for the study of brain circuits.

Where do cell states end and cell types begin?

High-throughput transcriptomics offers powerful new methods for defining different types of brain cells. But we need to think more explicitly about how we use these data to distinguish a cell’s permanent identity from its transient states.

This paper changed my life: John Tuthill reflects on the subjectivity of selfhood

Wittlinger, Wehner and Wolf’s 2006 “stilts and stumps” Science paper revealed how ants pull off extraordinary feats of navigation using a biological odometer, and it inspired Tuthill to consider how other insects sense their own bodies.
