Scientists used a stimulation technique to improve the sensitivity of peoples fingertips, and then gave them drugs that either doubled or deleted this effect. Similar skin stimulation/drug treatment combinations may eventually help the elderly or stroke victims button shirts and aid professional pianists according to the authors of a paper appearing in the 04 July issue of the journal Science, published by AAAS, the science society.
Finger stimulations and drugs can temporarily reorganize parts of the human brain. This stimulation, called co-activation, shuffles the synapses that link neurons. The stimulated area becomes more sensitive as more neurons are recruited to process encountered tactile information. The scientists showed that amphetamine doubled stimulation-induced gains in tactile acuity. In the presence of an alternate drug, an NMDA blocker, the improvements in tactile acuity, or perceptual learning, gained via finger stimulations were lost.
Dinse said that related treatments could improve a persons ability to read Braille and that drug-mediated muscle stimulation could help the elderly and chronic pain patients perform everyday tasks.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
