Hearing is made possible when hair bundles protruding from the tops of hair cells capture the energy of sound waves, converting them into electrical signals that stimulate the auditory nerve to the brain. These hair bundles ...

Loud noise, trauma, infections, plain old aging—many things can destroy hair cells, the delicate sensors of balance and sound within the inner ear. And once these sensors are gone, that's it; the delicate hair cells don't ...

Using a sensitive new technology called single-cell RNA-seq on cells from mice, scientists have created the first high-resolution gene expression map of the newborn mouse inner ear. The findings provide new insight into how ...

Johns Hopkins researchers have identified a novel cell signaling pathway in mice through which mammals—presumably including people—can regenerate hair follicles and skin while healing from wounds.

Unlike birds and amphibians, mammals can't recover lost hearing. In people, the cells of the inner ear responsible for detecting sound and transmitting those signals to the brain form during early stages of development and ...

Conventional wisdom has long blamed age-related hearing loss almost entirely on the death of sensory hair cells in the inner ear, but research from neuroscientists at Johns Hopkins has provided new information about the workings ...
