9 Conclusion
In this work we have examined the question if subliminal attacks to users of EEG-based braincomputer
interfaces (BCIs) are feasible. We have designed a proof-of-concept experiment in which
the attacker tries to infer if the user knows a particular person or not, without the user noticing that
she is being attacked. We hid visual stimuli in form of portrait photos of Barack Obama in a video
as well as other visual stimuli that serve as a contrast. In an experiment with 27 subjects we find that
our naive attack strategy is able to obtain 66% accuracy in predicting that a subject is familiar with
Barack Obama, while an advanced attack strategy that incorporates confidence levels is able to improve
the accuracy to 90%. The subjects achieved different levels of recognition in terms of detecting
the manipulation of the video. At each recognition level, the attack was successful for most users
including the users that did not notice any manipulation.

Our subliminal attacks have been carried out in a controlled setting to demonstrate their feasibility.
Future research directions include exploration of different pathways for improving the attack,
such as more sophisticated hiding mechanisms and internal subliminal validation techniques. The
findings presented in this work suggest that BCI software with the full access to raw EEG data of
users constitutes a new attack vector to user privacy and user secrets (arXiv:1312.6052v1 [cs.CR] 20 Dec 2013).

Direct Brain-to-Brain Communication in Humans: A Pilot Study
“We have demonstrated the first human brain-to-brain interface for a very simple form of transfer of information,” Rao said. Moreover, the prior brain-to-brain interfaces involved electrodes implanted directly into rat brains, “so this is the first noninvasive brain-to-brain interface as well.”
“I felt a bit like Alexander Graham Bell working on the first telephone,” said Rajesh Rao, the computational neuroscientist whose brain sent the signal (Washington Post).

Exo-hand. Extended cognition and embodiment is one way that we will work on Mars, from Earth, even with up to 16 minute radio signal delay. This video also nicely illustrates the awkwardness that substrate independent minds will encounter in various prosthetic configurations. Patience and perseverance won’t just be noble character traits, they will be among the most essential characteristics for long term post human adaptation and survival.

Scientific American:
A Countdown to a Digital Simulation of Every Last Neuron in the Human Brain. Building a vast digital simulation of the brain could transform neuroscience and medicine and reveal new ways of making more powerful computers. By the year 2020 digital brains may be able to represent the inner workings of a single brain cell or even the whole brain.
Including, as long promised here, the emergence of neuroprosthetics, mind-machine interfaces, and hybrid human and machine minds. Now, things can begin to get interesting.

Researchers have been improving upon BrainGate — a brain-machine interface that allows users to control an external device with their minds — for years, but what you see here is the most advanced incarnation of the implant system to date. It is nothing short of remarkable.

The author’s site lists this article as Waiting for the Bionic Man, so maybe Wired applied some kind of proprietary troll-baiting re-title algorithm to bump up the irritated enthusiast click through rate, or something: “A True Bionic Limb Remains Far Out of Reach.” Whatever. @MikeChorost‘s report is a fanstastic reality update to the previous post and indeed, all the content of this blog. We need much more of this to Get There!
From the article:
- Hypothetically, a neurally controlled prosthesis would begin with a brain interface, a chip capable of picking up complex signals from the user’s brain.
- A computer would translate those signals into orders for the arm—”move up,” “bend my elbow,” “turn my wrist.”
- Motors in the joints would move the arm smoothly in response to commands from the computer.
- Sensors in the arm would feed information on its position and movement through the computer and into the chip in the user’s brain.

Finally, someone else articulating this truth with the scientific authority that might be better heard and received.
