It's the first noninvasive human-to-human brain interface to do so
Many new studies have shown that people can control things -- like video games or a cursor on a screen
-- only with their thoughts, but a new project takes this to the next
level: people controlling other people with their thoughts.
A new study by University of Washington researchers -- led by Rajesh Rao
and Andrea Stocco -- created the first human-to-human brain interface
that is noninvasive. It allowed the thoughts of one researcher to
manipulate movement of another.
The study used electroencephalography (EEG) -- which is used to record
brain activity noninvasively from the scalp -- and transcranial magnetic
stimulation, which is a noninvasive way of delivering stimulation to
the brain to obtain a response.
Rao sat in his laboratory, where he wore a cap hooked up to electrodes.
The electrodes were connected to an electroencephalography machine in
order to read the electrical activity in his brain.
Meanwhile, Stocco was in his laboratory across campus with a swim cap
marked with the stimulation site for the transcranial magnetic
stimulation coil. The coil was positioned over his left motor cortex,
which controls hand movement. There was a Skype connection between the
two labs for coordination purposes, but neither Stocco nor Rao could see
the Skype screens.
Rao was playing a video game with his mind,
where he had to imagine moving his right hand in order to fire a cannon
at a specific target. When he did this correctly, a cursor would hit
the "fire" button.
Other researchers on the team (computer science and engineering
undergraduates Matthew Bryan, Bryan Djunaedi, Joseph Wu and Alex Dadgar,
along with bioengineering graduate student Dev Sarma) wrote the
computer code for the study, which translated Rao’s brain signals into a
command for Stocco’s brain.
While Rao did this, Stocco -- who ore noise-canceling earbuds and wasn’t
looking at a computer screen back in his own laboratory --
involuntarily moved his right index finger to push the space bar on the
keyboard in front of him (as if firing the cannon in the game).
“It was both exciting and eerie to watch an imagined action from my
brain get translated into actual action by another brain,” Rao said.
“This was basically a one-way flow of information from my brain to his.
The next step is having a more equitable two-way conversation directly
between the two brains.”
Previous studies have successfully connected the brains of two rats as well as a human and a rat, but never two humans.
The researchers assured that their technology could never allow one
person to control another without their consent, and that it could one
day be used for people with disabilities who cannot communicate in other ways.
“The Internet was a way to connect computers, and now it can be a way to
connect brains,” Stocco said. “We want to take the knowledge of a brain
and transmit it directly from brain to brain.”
Federal judge: Bitcoin, “a currency,” can be regulated under American law
Bitcoin Savings and Trust's founder has been accused of running a Ponzi scheme.
In the case of a Texas man accused
of massive Bitcoin-based fraud, a federal judge has ruled that bitcoins
are “a currency or form of money," and are therefore subject to
relevant US laws.
The case revolves around Bitcoin Savings and Trust (BTCST), a virtual Bitcoin-based hedge fund that many suspected of being a scam. BTCST shut down in August 2012, and the Securities and Exchange Commission (SEC) last month formally charged founder Trendon Shavers with running a Ponzi scheme.
As we previously reported, the SEC has said Shavers “raised at least 700,000 bitcoins in BTCST investments, which amounted to more than $4.5 million based on the average price of bitcoins in 2011 and 2012 when the investments were offered and sold.”
Shavers did not immediately respond to our request for comment.
In a four-page memorandum opinion issued on Tuesday, Judge Amos Mazzant wrote (PDF) to determine whether his court has jurisdiction in the case.

However, the question currently before the Court is whether the BTCST investments in this case are securities as defined by Federal Securities Laws. Shavers argues that the BTCST investments are not securities because Bitcoin is not money, and is not part of anything regulated by the United States. Shavers also contends that his transactions were all Bitcoin transactions and that no money ever exchanged hands. The SEC argues that the BTCST investments are both investment contracts and notes, and, thus, are securities.Earlier this year, a US federal agency, the Financial Crimes Enforcement Network (FinCEN), published new guidelines stipulating that Bitcoin-related businesses should be considered as Money Services Businesses under US law.
. . .
It is clear that Bitcoin can be used as money. It can be used to purchase goods or services, and as Shavers stated, used to pay for individual living expenses. The only limitation of Bitcoin is that it is limited to those places that accept it as currency. However, it can also be exchanged for conventional currencies, such as the U.S. dollar, Euro, Yen, and Yuan. Therefore, Bitcoin is a currency or form of money, and investors wishing to invest in BTCST provided an investment of money.
