Cognitive Functions

Biomimetic Implant PDF Document "Boosting Our Gray Matter," Business Week, Sep 2007
Working with rats, University of Southern California's Theodore W. Berger learned how neurons responsible for memory react to varying patterns of electrical stimulation. His team has turned those reactions into equations on chips, which will soon be implanted in a rat's hippocampus.

Biomimetic Implant PDF Document "The Ideas Engine Needs A Tuneup," Washington Post, Jun 2007
David Ignatius reports from the Highlands Conference, a Pentagon-funded group that brings together defense officials and scientists for regular discussions. Dr. Berger's presentation and the Center for Neural Engineering research was particularly noted as "most impressive."

Biomimetic Implant PDF Document "The Memory Hacker," Popular Science, Apr 2007
Ted Berger has spent the past decade engineering a brain implant that can recreate thoughts. The chip would remedy everything from Alzheimer's to absent-mindedness — and reduce memory loss to nothing more than a computer glitch.

Biomimetic Implant PDF Document "Chipping In," SciAmerican, Feb 2007
Supplanting the human brain with computer power has been a staple of science fiction. Scientific American looks at the replacement of damaged brain tissue in rats with a neural prosthesis at the Neural Engineering Labs at USC.

The work of Jose Delgado, a pioneering star in brain-stimulation research four decades ago, goes largely unacknowledged today. What happened?

Biomimetic Implant PDF Document "Frontiers Of Science," Discover, October 2005
The bionic age begins. Neural implants treat tremors, paralysis, and even memory loss.

Biomimetic Implant PDF Document "A New Kind of Memory," Newsweek, October 2004
Ted Berger squints through a microscope at a slice of rat brain the size of an infant's fingernail. It's resting on an array of microelectrodes, which eavesdrops on the murmrs of nerve cells.

Biomimetic Implant PDF Document "Chips Coming to a Brain Near You," Wired, October 2004
In this era of high-tech memory management, next in line to get that memory upgrade isn't your computer, it's you.

Biomimetic Implant PDF Document "Brain Prosthesis Passes Live Tissue Test," NewScientist, October 2004
"The microchip, designed to model a part of the brain called the hippocampus, has been used successfully to replace a neural circuit in slices of rat brain tissue kept alive in a dish...The device could ultimately be used to replace damaged brain tissue which may have been destroyed in an accident, during a stroke, or by neurodegenerative conditions such as Alzheimer's disease. It is the first attempt to replace central brain regions dealing with cognitive functions such as learning or speech."

Biomimetic Implant PDF Document "Can An Electronic Device Replace Damaged Brain Circuits," Popular Science, June 2003.pdf
Biomedical engineer Theodore Berger has created a 2 mm-wide silicon chip that he hopes will one day substitute for damaged or diseased brain regions.

Biomimetic Implant PDF Document "World's First Brain Prosthesis Revealed," New Scientist, March 2003
The world's first brain prosthesis — an artifical hippocampus — is about to be tested in California. Unlike devices like cochlear implants, which merely stimulate brain activity, this silicon chip implant will perform the same processes as the damaged part of the brain it is replacing.

Biomimetic Implant PDF Document "Building the Bionic Brain" Trojan Family Magazine, Winter 2002
Neurons and silicon commingling in a soup of living, cognitively functioning "wetware"? It sounds like science fiction, but for Ted Berger and his crack team of USC neuroscientists, computer whizzes and biomedical and electrical engineers, it’s a break-through about to happen.

Biomimetic Implant PDF Document "USC Engineers Look to the Brain For the Next-Generation Computer,"USC News Service July 2002
USC Engineers are tapping the brain to develop the next generation of computer chip, a chip that will be more resilient to damage and better at a host of tasks involving pattern recognition.

Biomimetic Implant PDF Document "What's Next; A Chip That Mimics Neurons," New York Times, June 2002
One day, a computer chip may do some of the work of a damaged hippocampus, replacing living neurons with silicon ones.

Biomimetic Implant PDF Document "Brain Implantable Biomimetic Electronics," Proceedings of the IEEE, July 2001
An interdisciplinary miltilaboratory effort to devlop an implantable neural prosthetic that can coexist and bidirectionally communicate with living brain tissue is described.
