On the (sound) track of anesthetics
03-06-2007 · EurekAlert!Danish scientists challenge the accepted scientific views of how nerves function and of how anesthetics work. Their research suggests that action of nerves is based on sound pulses and that anesthetics inhibit their transmission.

A new study has found how one of the most commonly used anesthetics may produce Alzheimer's-like changes in the brain. Researchers from Massachusetts General Hospital and colleagues describe the mechanism by which the anesthetic isoflurane may induce both the cell-death process known as apoptosis and the generation of amyloid-beta protein in cultured neural cells.

- Mapping the selective brain
11-21-2007 · EurekAlert!
Researchers have added a new piece to the puzzle of how the brain selectively amplifies those distinctions that matter most from the continuous cascade of sights, sounds, and other sensory input. Whether recognizing a glowering face among smiling ones or the unmistakable sound of a spouse calling one's name, such "categorical perception" is central to sensory function.
