University of Washington researchers have demonstrated a non-invasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.

Previously, researchers at Duke University had demonstrated brain-to-brain communication between two rats. But University of Washington researchers Rajesh Rao and Andrea Stocco believe theirs is the first demonstration of human-to-human brain interfacing.

The technologies used by the researchers for recording brain signals and delivering them to the receiver are not new. Electroencephalography (EEG) is routinely used by clinicians and researchers to record brain activity non-invasively from the scalp.

To deliver the signal to the recipient, transcranial magnetic stimulation (TMS) was used. TMS is a non-invasive way of stimulating the brain to elicit a response. Its effect depends on where the scalp coil is placed; in this case, it was placed directly over the brain region that controls a person's right hand. By activating these neurons, the stimulation convinced the brain that it needed to move the right hand.

Co-researchers Matthew Bryan, Bryan Djunaedi, Joseph Wu, Alex Dadgar, and Dev Sarma, wrote the computer code that translates Rao's brain signals into a command for Stocco's brain.

The demonstration was carried out earlier this month, when Rao sat in his lab wearing a cap with electrodes hooked up to an electroencephalography machine. Stocco was in his lab across campus wearing a swim cap marked with the stimulation site for the TMS coil that was placed directly over his left motor cortex, which controls hand movement.

The team had a Skype connection set up so the two labs could coordinate, but neither Rao nor Stocco could see the Skype screens.

For the demonstration, Rao looked at a computer screen and played a simple video game with his mind. When he was supposed to fire a cannon at a target, he imagined moving his right hand (without actually move his hand), causing a cursor to hit the "fire" button. Almost instantaneously, Stocco, who was wearing noise-canceling earbuds and not looking at a computer screen, involuntarily moved his right index finger to push the space bar on the keyboard in front of him, as if firing the cannon.

Stocco compared the feeling of his hand moving involuntarily to that of a nervous tic.

"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."

Rao stressed the technology only reads certain kinds of simple brain signals, not a person's thoughts. "I think some people will be unnerved by this because they will overestimate the technology," Prat added. "There's no possible way the technology that we have could be used on a person unknowingly or without their willing participation."

The researchers next plan to conduct an experiment that would transmit more complex information from one brain to the other. Stocco said years from now the technology could be used, for example, by someone on the ground to help a flight attendant or passenger land an airplane if the pilot becomes incapacitated. Or a person with disabilities could communicate his or her wish, say, for food or water. The brain signals from one person to another would work even if they didn't speak the same language.

Build it into a rather large hat, equip with a hidden wireless transmitter and control your own zombie army.

The erectile reflex is originated in the local parasympathetic nerves, mediated at the spinal cord level and modulated by pathways originating in the raphe nuclei in the brain stem. The medial preoptic area and the paraventricular nucleus are integrating centers.

All this time and I thought they'd just use a USB cable.

Was thinking more eSATA, actually.

This sentence did nothing to stimulate my penis.

basically attach a neural stimulator at the brain stem and you can walk around with perminent erection.

Awesome. How can I hook that **** up to an xbox controller? I wish to perform a 50+ hit Ultra Combo on myself. (or get into a bit of multi player action, once I've learned the moves)
