The brain is bombarded by information about the physical proportions of our bodies. The most familiar sensations, such as a puff of wind or the brush of our own shirt sleeve, serve to constantly remind the brain of the bodys outer bounds, creating a sense of what is known as proprioception. In a new study, researchers report this week that the brains ability to interpret external signals and update its sense of bodily self is more dynamic than had been previously thought and that such updates can happen very quickly, altering within a matter of seconds how body parts and individual touch sensations are perceived.
The work is reported by researchers Frederique de Vignemont, Henrik Ehrsson, and Patrick Haggard at University College London.
The information that is integrated in the course of proprioception comes from several different senses, including touch, pain, vision, information from muscles, and so on. The brain must combine all these information inputs to accurately perceive the external world through our bodys interaction with it and also to produce a coherent sense of self. Because all these signals carry such different kinds of information, the brain must perform a constant juggling act in order to make sense of the body and the world.

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...
