Web-crawling the brain
The brain is a black box. A complex circuitry of neurons fires information through channels, much like the inner workings of a computer chip. But while computer processors are regimented with the deft economy of an assembly ...

Neurobiologists find that weak electrical fields in the brain help neurons fire together
The brain -- awake and sleeping -- is awash in electrical activity, and not just from the individual pings of single neurons communicating with each other. In fact, the brain is enveloped in countless overlapping ...
