...close this window" button. If your desktop is overcrowded with windows, you can hit an icon that will line them all up for you, tilted at an angle, so you can pluck out the one that you need. Nice - but at the same time, it breaks with the visual metaphor of a flat desktop...
...everybody loves a show-off, of course. Natalie Jeremijenko, assistant professor at the Department of Visual Arts at the University of California, San Diego, says we should use robots to find creative solutions to the world around us rather than seeking a pleasing yap and wag at the push of a button. Working with teams of high school students, she tricks out toy robots - she calls them "feral robot dogs" - with all-terrain wheels and pollution sensors in their noses and sends them into landfills and industrial areas to search for toxins. These are robots with a social conscience. "Suddenly...
Monkeys experience binocular rivalry. They can learn to press a button every time their perception flips, while their brains are impaled with electrodes that record any change in activity. Neuroscientist Nikos Logothetis found that the earliest way stations for visual input in the back of the brain barely budged as the monkeys' consciousness flipped from one state to another. Instead, it was a region that sits further down the information stream and that registers coherent shapes and objects that tracks the monkeys' awareness. Now this doesn't mean that this place on the underside of the brain...
...first discoveries of neuroplasticity came from studies of how changes in the messages the brain receives through the senses can alter its structure and function. When no transmissions arrive from the eyes in someone who has been blind from a young age, for instance, the visual cortex can learn to hear or feel or even support verbal memory. When signals from the skin or muscles bombard the motor cortex or the somatosensory cortex (which processes touch), the brain expands the area that is wired to move, say, the fingers. In this sense, the very structure of our brain--the relative...
...past few years has overthrown the dogma. In its place has come the realization that the adult brain retains impressive powers of "neuroplasticity"--the ability to change its structure and function in response to experience. These aren't minor tweaks either. Something as basic as the function of the visual or auditory cortex can change as a result of a person's experience of becoming deaf or blind at a young age. Even when the brain suffers a trauma late in life, it can rezone itself like a city in a frenzy of urban renewal. If a stroke knocks...
