Close your eyes and acutely listen to the sounds around you, and youll find youre able not only to accurately place the location of sounds in space, but their motion. Imagine then that, strangely, you suddenly became unable to distinguish the motion of sounds, even while you retained the ability to pinpoint their location. Thats exactly the experience of a patient reported by Christine Ducommun and her colleagues, who used studies of the patient to demonstrate conclusively for the first time that the brain has a specialized region for processing sound motion.
While it was known that the visual system has a specialized region for perceiving motion, it wasnt known whether the auditory system has such a region--or whether sound location and motion are processed by the same circuitry. Previous studies of the capabilities of brain-damaged patients had found only that both their location and motion processing abilities were impaired, and animal and human neuroimaging studies had not been able to conclusively tease apart the two abilities.
Ducommun and her colleagues discovered the region by studying a woman who was to be operated on to alleviate intractable temporal lobe epilepsy. The operation would involve the removal of the affected regions of the right anterior temporal lobe and the right posterior superior temporal gyrus (STG).

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
