Cells in retina change their duties to help the brain detect motion
To see under starlight and moonlight, the retina of the eye changes both the software and hardware of its light-sensing cells to create a kind of night vision. Retinal circuits that were thought to be unchanging and programmed for specific tasks are adaptable to different light conditions, say the Duke scientists who identified how the retina reprograms itself for low light.
Esta es sólo una forma de intentar describir algo muy inexplicable para la mente…la Conciencia ..,,
Sólo una experiencia directa de la conciencia permite que saboreemos su realidad pero sólo en el nivel que estemos…habiendo una gran cantidad de niveles de Conciencia, tal vez infinitos …. Leer Más

Balance is extraordinarily important in your life. Whether you’re older than 65 years or younger, both your body and mind require balance to achieve optimal health. Unfortunately, many spend hours behind a desk each day, increasing their risk of impairing muscle development and losing strength and balance.
Not content with being a half-a-trillion-dollar company with 2 billion users worldwide, Facebook casually announced this week it hadinvented a new unit of time. The “flick,” at 1/705,600,000th of a second, is longer than a nanosecond (1/1,000,000,000th of a second), and is designed to measure the time individual video frames appear on screen.
The architecture of the downtown Cleveland Clinic Lou Ruvo Center for Brain Health is brilliantly designed by architectural ace Frank Gehry to resemble a scrambled brain that indicates dementia — an ever increasing problem in our society, especially as the population ages.
Dos estudios diferentes señalan cuál es el deporte más adecuado para prevenir enfermedades como la demencia senil más grave.
Scientists have linked physical exercise to brain health for many years.
In fact, there’s compelling evidence that physical exercise helps build a brain that not only resists shrinkage, but increases cognitive abilities1 by promoting neurogenesis, i.e. your brain’s ability to adapt and grow new brain cells. Leer Más
“Get up and move.” That’s the take-home message from a new study from Ezra Fishman, a doctoral candidate in demography at the University of Pennsylvania, and colleagues from Johns Hopkins University, the National Cancer Institute, the National Institute on Aging and others. Leer Más
