Cdn. researcher: Cells can grow on silicon




CALGARY (CP) -- Researchers at the University of Calgary have found that nerve cells grown on a microchip can learn and memorize information which can be communicated to the brain.

"We discovered that when we used the chip to stimulate the neurons, their synaptic strength was enhanced," said Naweed Syed, a neurobiologist at the University of Calgary's faculty of medicine.

The nerve cells also exhibited memory traces that were successfully read by the chip, said Syed, co-author of the landmark study published in February's edition of Physical Review Letters, an international journal.

The research was done in collaboration with the Max Planck Institute for Biochemistry in Munich, Germany.

The team cultured nerve cells from a snail and placed them on a specially designed silicon chip. Using a microcapacitor on the chip, scientists stimulated one nerve cell to communicate with a second cell which transmitted that signal to multiple cells within the network.

A transistor located on the chip then recorded that conversation between cells.

Syed said the discovery is groundbreaking.

"We've made a giant leap in answering several fundamental questions of biology and neuro-electronics that will pave the way for us to harness the power of nanotechnology," he said.

The findings could help in the design of devices that combine electronic components and brain cells. That includes controlling artificial limbs or restoring sight for the visually impaired.

Future research will focus on interfacing silicon chips with the human brain to control artificial limbs and develop "thinking" computers.

So they created a stimulus <--> feedback situation, where the nerve cells acted as a conduit.

That's fucking awesome.

Sitting beside me on my desk is a 500-page book on neural nets and cognitive theory from MIT press; but I feel like it's so outdated now, with the awesome advances in technology I've been hearing about like this one.

We're moving ahead at a frightening pace, wouldn't you say?? :)

how wonderful that the Germans are working on technology to make Uber-humans, im sure theres no reason to suspect they may use this technology to build a "master" race of some sort... i mean that was like what 50 years ago...

hA!!

They're developing this technology so they can re-insert Hilters brain in to some host.

AHHHH! WHAT THE FUCK!?

That was a mouse that had a plastic frame in the shape of an ear put under its skin, and the skin grew around it.

Nothing too freaky, just stupid science at its best. And it gets people up in arms, since they think that somehow a human ear was grown on a mouse.

BTW there are mice that "glow in the dark". The have GFP (greeen flouresence protein) tagged to genes of interest and under the corerect stimuli theses genes can be visualized so that you can see where the the mouse is expressing the gene of interest.

We use them to track the expression of viral vectors used for gene therapy to ensure high levels of transcription.
