The line between living organisms and machines has just become a whole lot blurrier. European researchers have developed "neuro-chips" in which living brain cells and silicon circuits are coupled together.

The achievement could one day enable the creation of sophisticated neural prostheses to treat neurological disorders or the development of organic computers that crunch numbers using living neurons.




To create the neuro-chip, researchers squeezed more than 16,000 electronic transistors and hundreds of capacitors onto a silicon chip just 1 millimeter square in size.

They used special proteins found in the brain to glue brain cells, called neurons, onto the chip. However, the proteins acted as more than just a simple adhesive.

"They also provided the link between ionic channels of the neurons and semiconductor material in a way that neural electrical signals could be passed to the silicon chip," said study team member Stefano Vassanelli from the University of Padua in Italy.

The proteins allowed the neuro-chip's electronic components and its living cells to communicate with each other. Electrical signals from neurons were recorded using the chip's transistors, while the chip's capacitors were used to stimulate the neurons.

t could still be decades before the technology is advanced enough to treat neurological disorders or create living computers, the researchers say, but in the nearer term, the chips could provide an advanced method of screening drugs for the pharmaceutical industry.

"Pharmaceutical companies could use the chip to test the effect of drugs on neurons, to quickly discover promising avenues of research," Vassanelli said.

The researchers are now working on ways to avoid damaging the neurons during stimulation. The team is also exploring the possibility of using a neuron's genetic instructions to control the neuro-chip.

i herad about this shit they said with this in the future they will be able to find out all your thoughts and memories from this and probably control wut u do. It will cure disease and get rid of crime and violence but take away peoples individuality. im cool off this shit the gov't aint puttin a chip in my head even if it will cure cancer.

Paralyzed Man Moves Computer Cursor With His Mind

A Paralyzed man has been able to move a computer cursor, open e-mail and control a robotic device simply by thinking about doing it, a team of scientists said on Wednesday.

They believe a new brain sensor, called BrainGate, could offer new hope to people Paralyzed by injuries or illnesses.

"This is the first step in an ongoing clinical trial of a device that is encouraging for its potential to help people with paralysis," said Dr Leigh Hochberg, of Massachusetts General Hospital.

The 25-year-old man who suffered paralysis of all four limbs three years earlier completed tasks such moving a cursor on a screen and controlling a robotic arm.

He is the first of four patients with spinal cord injuries, muscular dystrophy, stroke or motor neurone disease testing the brain-to-movement system.

"This is the dawn of major neurotechnology where the ability to take signals out of the brain has taken a big step forward. We have the ability to put signals into the brain but getting signals out is a real challenge. I think this represents a landmark event," said Professor John Donoghue of Brown University in Rhode Island.

The scientists implanted a tiny silicon chip with 100 electrodes into an area of the brain responsible for movement. The activity of the cells was recorded and sent to a computer which translated the commands and enabled the patient to move and control the external device.

"This part of the brain, the motor cortex, which usually sends its signals down the spinal cord and out to the limbs to control movement, can still be used by this participant to control an external device, even after years had gone by since his spinal cord injury," added Hochberg, a co-author of the study published in the journal Nature.

Although it is not the first time brain activity has been used to control a cursor, Stephen Scott of Queen's University in Ontario, Canada said it advances the technology.

"This research suggests that implanted prosthetics are a viable approach for assisting severely impaired individuals to communicate and interact with the environment," he said in a commentary in the journal.

Paralyzed man moves computer cursor through thought



A Paralyzed man using a new brain sensor has been able to move a computer cursor, open e-mail and control a robotic device simply by thinking about doing it, a team of scientists said on Wednesday.

They believe the BrainGate sensor, which involves implanting electrodes in the brain, could offer new hope to people Paralyzed by injuries or illnesses.

"This is the first step in an ongoing clinical trial of a device that is encouraging for its potential to help people with paralysis," Dr Leigh Hochberg, of Massachusetts General Hospital, said in an interview.

The 25-year-old man who suffered paralysis of all four limbs three years earlier completed tasks such moving a cursor on a screen and controlling a robotic arm.

He is the first of four patients with spinal cord injuries, muscular dystrophy, stroke or motor neurone disease testing the brain-to-movement system developed by Cyberkinetics Neurotechnology Systems Inc <CYKN.OB> in Massachusetts.

In a separate study, researchers from Stanford University Schools of Medicine and Engineering described a faster way to process signals from the brain to control a computer or prosthetic device.

"Our research is starting to show that, from a performance perspective, this type of prosthetic system is clinically viable," Stephen Ryu, an assistant professor of neurosurgery at Stanford, said in as statement.

^^I think I posted a related article some months back. I know a couple of years ago I posted an aritcle about monkies controlling robotic arms with their minds as well.

It's really exciting to think about all the great possabilities these technologies can lead us to.

Look at the anatomy of a neuron. the ions do not pass from neuron to neuron. Neurotransmitters pass from neuron to neouron. Ions spread the information intracellularly. So how can ions which only propogate the action potential convey the intended signal to an outside source without interfering with the signals propogation?
