Review

39. In June, 2000, a team of researchers at the Massachusetts Institute of Technology and Bell Labs reported that they had created an electronic circuit based on the cerebral cortex, the brain’s centre of intelligence. Lauded as the first artificial circuit to mimic brain activity, it was modelled on the much larger network of natural neurons and feedback loops in the human brain. Use several sources to research artificial intelligence or neuromorphic engineering, and find out how this circuitry works. Search for information in newspapers, periodicals, CD-ROMs, and on the Internet.

Artificial Intelligence
Artificial Intelligence is a Web site published for students by the American Association of Artificial Intelligence. Loads of information is offered, with news stories, tons of links, and some interactive activities.

Electronic Circuit that Mimics the Brain
In 2000, the MIT press office released the news that researchers had developed an Electronic Circuit that Mimics the Brain. Read the breaking story here.

When will computer hardware match the human brain?
When will computer hardware match the human brain? asks this journal article. The conclusion: New developments in hardware technology should allow researchers to build robotic brains that match our own in a couple of decades.

Electronic Circuit Replicates Brain Activity
Electronic Circuit Replicates Brain Activity is an article explaining MIT's groundbreaking research. Several related links are listed at the bottom of the page.

Artificial Brains
