All ears: Genetic bases of mammalian inner ear evolution

Mammals have adapted to live in the darkest of caves and the deepest oceans, and from the highest mountains to the plains. Along the way, mammals have also adapted a remarkable capacity in their sense of hearing, from the ...

Mechanism helps explain the ear's exquisite sensitivity

The human ear, like those of other mammals, is so extraordinarily sensitive that it can detect sound-wave-induced vibrations of the eardrum that move by less than the width of an atom. Now, researchers at MIT have discovered ...

Determining fish age using inner ear structures

Biologists in Japan have identified four distinct zones in the otolith, a calcium carbonate structure in the inner ear, which can be used to determine age in fish.

Evolution of the inner ear: Insights from jawless fish

Researchers at the RIKEN Center for Biosystems Dynamics (BDR) and collaborators have described for the first time the development of the hagfish inner ear. Published in the journal Nature, the study provides a new story for ...

Connecting hearing helper molecules to the ear bone

Researchers at USC and Harvard have developed a new approach to repair cells deep inside the ear—a potential remedy that could restore hearing for millions of elderly people and others who suffer hearing loss.

Inner ear

The inner ear is the bony labyrinth, a system of passages comprising two main functional parts:

Inner ears are found in all vertebrates, with substantial variations in the form and function of their sensory organs. Each animal has two inner ears, one on each side of its head.
