Stanford study of owls finds link in brain between sight and sound

Just imagine listening to someone talk and also hearing the buzz of the overhead lights, the hum of your computer and the muffled conversation down the hallway. To focus on the person speaking to you, your brain clearly can't give equal weight to all incoming sensory information. It has to attend to what ...

World first research to speed up cure for ear infections

...e commonly known as an ear infection ?which causes hearing loss and can lead to more serious disorders such as meningitis. Ear infections can occur when ear drums burst as a result of a loud explosion, trauma or most commonly by infection spread by a common cold or sore throat. LEHI's Senior Research Scien...

Chemical signaling helps regulate sensory map formation in the brain

...ought to regulate other sensory systems -- such as hearing and touch, as well as motor systems -- but the visual system has been the predominant model system for studying the development of such maps and the gradients of guidance molecules that control their formation. Scientists have searched for these gra...

Research tracks whales by listening to sounds

... complexities of communicating." Scientists began hearing whale sounds several years ago on a U.S. Navy hydrophone network. The hydrophone system ?called the Sound Surveillance System, or SOSUS ?was used by the Navy during the Cold War to monitor submarine activity in the northern Pacific Ocean. As the Cold...
