Unveiling the Intricate Wireless Maps of Brain-Cell 'Antennae' and Worm's Nervous System

Scientists have created a detailed 3D map of the primary cilia, tiny hairlike structures found on the surface of brain cells, across the human cortex. These cilia act as antennae, sensing signals from the environment and passing them to the cell's nucleus. The map, which details 56,000 cells, could guide research into ciliopathies, diseases caused by disruptions in cilia function. The study revealed that cilia differ in size and shape depending on the cell type and cortical layer, and they are embedded in the brain's connectome. Further research will explore how primary cilia influence neural circuits and their potential use in treating neurological disorders.
