Newly discovered hair cells on squid may offer clues to understanding hearing loss in humans
Scientists have known for years that squid have cells with bundles of tiny, hairlike protrusions on their heads and arms, similar to those buried deep inside the human ear that allow us to hear. Now, researchers at Case Western Reserve University have discovered that these animals have hundreds more of these cells, called hair cells, lining the entire surface of their bodies. The discovery may…
Scientists have identified hundreds of previously unknown hair cells on the surface of squid's bodies, which may offer new insights into human hearing loss. These hair cells, called lateral lines, are an array of tiny, hairlike protrusions that detect changes in water pressure. The discovery was made by researchers at Case Western Reserve University, who used a state-of-the-art imaging technique called light sheet microscopy to map the cells' locations.
The team found that the length of each hair bundle varies, similar to the structure of hair cells in the human ear, which helps tune the ear to different frequencies. Understanding how these squid hair cells work could provide valuable information about how hearing loss occurs in humans, particularly when hair bundles are damaged.
