By reexamining 3D images used to map the connections between brain cells, researchers are uncovering new information about a small, elusive, and often overlooked cellular appendage.

Cilia drive fluid flow in development and physiology, but this requires that all cilia in a tissue orient the same way. Earlier studies indicated that both planar cell polarity (PCP) signalling ...

They provide nanometer-scale views of all the cells and structures in a volume of tissue—including cilia. "Every time you look into these large-scale volume data sets, you are seeing new biology ...
