[LINK] “Brains of rats connected allowing them to share information via internet”
The Guardian‘s Ian Sample reports on a rather remarkable new technological development. The paper’s title is “A Brain-to-Brain Interface for Real-Time Sharing of Sensorimotor Information”, but I’ve seen people on Facebook talking about rat telepathy, too.
Scientists have connected the brains of a pair of animals and allowed them to share sensory information in a major step towards what the researchers call the world’s first “organic computer”.
The US team fitted two rats with devices called brain-to-brain interfaces that let the animals collaborate on simple tasks to earn rewards, such as a drink of water.

Led by Miguel Nicolelis, a pioneer of devices that allow paralysed people to control computers and robotic arms with their thoughts, the researchers say their latest work may enable multiple brains to be hooked up to share information.

The scientists first demonstrated that rats can share, and act on, each other’s sensory information by electrically connecting their brains via tiny grids of electrodes that reach into the motor cortex, the brain region that processes movement.
The rats were trained to press a lever when a light went on above it. When they performed the task correctly, they got a drink of water. To test the animals’ ability to share brain information, they put the rats in two separate compartments. Only one compartment had a light that came on above the lever. When the rat pressed the lever, an electronic version of its brain activity was sent directly to the other rat’s brain. In trials, the second rat responded correctly to the imported brain signals 70% of the time by pressing the lever.
Remarkably, the communication between the rats was two-way. If the receiving rat failed at the task, the first rat was not rewarded with a drink, and appeared to change its behaviour to make the task easier for its partner. In further experiments, the rats collaborated in a task that required them to distinguish between narrow and wide openings using their whiskers.
In the final test, the scientists connected rats on different continents and beamed their brain activity back and forth over the internet. “Even though the animals were on different continents, with the resulting noisy transmission and signal delays, they could still communicate,” said Miguel Pais-Vieira, the first author of the study, in a statement. “This tells us that we could create a workable network of animal brains distributed in many different locations.”

Noel, do you have any insights on the situation described in this New York Times article?
For a start-up that has a hit video game for the iPhone, the new loft-style offices of Ironhide Game Studio are exactly what one would expect — a newly hired staff labors feverishly on software updates not far from a pinball machine and custom-built monster arcade cabinet intended for letting off steam.
But the company, a success in the fiercely competitive field of video game development, stands out from other high-tech ventures in one respect: its unconventional location, which frequently confuses people abroad. “They politely ask, ‘Where is Uruguay?’ ” said Álvaro Azofra, one of the three founders of Ironhide, the company behind Kingdom Rush, a lucratively popular game in the United States that involves a cartoonish kingdom under attack by marauding yetis and ogres.
Squeezed between Brazil and Argentina and long dependent on commodities exports, Uruguay may be better known for its flocks of sheep and herds of cattle. But attention is now shifting to the country’s growing constellation of start-ups that are engineering video games for computers and hand-held devices.
Developers point to a variety of reasons that Uruguay has been able to compete with South America’s larger economies, whether the creativity of its engineers and commercial artists or its relatively relaxed immigration rules and extensive use of computers in schools.

Gaming studios have also emerged in São Paulo and Rio de Janeiro, Brazil’s two largest cities, but developers there complain of byzantine tax regulations and labor rules that make hiring employees costlier than in some rich industrialized countries. In Argentina, dozens of game-developing start-ups have been founded in Buenos Aires.
But while Argentina has traditionally had more companies in the industry, some of the momentum is seen shifting across the border to Uruguay as Argentine ventures struggle with abrupt changes in economic policy, including the tightening of currency controls that have complicated operations for exporters.
