Building a Silicon Brain. prostoalex tips us to an article in MIT's Technology Review on a Stanford scientist's plan to replicate the processes inside the human brain with silicon. Quoting: "Kwabena Boahen, a neuroengineer at Stanford University, is planning the most ambitious neuromorphic project to date: creating a silicon model of the cortex. The first-generation design will be composed of a circuit board with 16 chips, each containing a 256-by-256 array of silicon neurons. Groups of neurons can be set to have different electrical properties, mimicking different types of cells in the cortex. Engineers can also program specific connections between the cells to model the architecture in different parts of the cortex."[Slashdot] 10:11:22 PM      Google It!.

Recognizing Scenes Like the Brain Does. Roland Piquepaille writes "Researchers at the MIT McGovern Institute for Brain Research have used a biological model to train a computer model to recognize objects, such as cars or people, in busy street scenes. Their innovative approach, which combines neuroscience and artificial intelligence with computer science, mimics how the brain functions to recognize objects in the real world. This versatile model could one day be used for automobile driver's assistance, visual search engines, biomedical imaging analysis, or robots with realistic vision. Here is the researchers' paper in PDF format." [Slashdot] 1:13:01 PM      Google It!.

The brain scan that can read people's intentions. A team of world-leading neuroscientists has developed a powerful technique that allows them to look deep inside a person's brain and read their intentions before they act. The team used high-resolution CT brain scans to identify patterns of activ... [KurzweilAI.net Accelerating Intelligence News] 12:55:12 PM      Google It!.
