In The Wall Street Journal, (Personal Journal section, page D 3) there is an article entitled "Mysterious Brain Circuitry Becomes Viewable". "Researchers at Stanford University for the first time recorded 1,000 neurons working together in a LIVING brain for a month." (I capitolized living for emphasis)
All I can say is WOW!
But Stanford is not the only ones lighting the brain up. There is innovation exploding around the world. For example, scientists are wrapping the brain in soft sheets of microsopic sensor circuits, using cell sized diodes, turning the brain into a wireless transmittor.
Scientists want to transform crude forms of imaging, like functional MRI, into detailed pictures thhat can show details how the human brain's 100 billion neurons link into circuits through trillions of pathways.
