Researchers have demonstrated that a genetic switch for organ regeneration exists, after restoring damaged outer ears in mice ...

Firstly, and perhaps crucially, the folds in the pinna assist in determining the direction of sound (localization). This ...

Research led by the National Institute of Biological Sciences in Beijing has discovered that switching on a single dormant ...

The ear’s outer flap, called the pinna, acts as a sound-gatherer, “a bit like a horn,” Dr. Ricketts says. That horn is pointed slightly to the front, allowing the ear to gather more sound ...

Scientists discovered that human subjects who shifted their gaze to the left or right weakly activated a muscle within the posterior wall of the outer ear, or pinna.

The subtle movements of the ears were made visible by applying computer-based motion magnification techniques. Depending on the type of aural stimulus used, the researchers were able to observe ...

The scientists, co-led by Wei Wang, PhD, and colleagues, performed a side-by-side genetic comparison between mammal species—including rabbits—that can regenerate ear tissue and those ...

The outer ear (pinna) is designed by nature to work like an acoustic antenna. It helps the brain localize and tune in to a particular sound, for example when listening to a specific voice in a ...

In a sense, the inner ear bones of the Lufengpithecus is a missing link in the evolutionary history of human locomotion. It all comes down to bipedalism, or the fact that humans walk on two legs.
