Unlike conventional computer hardware, the word positronic implies that electrical current is carried in the wires of these robots’ brains by positrons, the antimatter counterpart of the familiar electron. Though the advantage of antimatter here is anyone’s guess, the stories of I, Robot may have introduced the positron to the public. And as bizarre as Asimov’s fantasy sounds, neuroimaging has given the term “positronic brain” yet another meaning.
This weekend, I attended a special event at NASA’s Jet Propulsion Laboratories in Pasadena, CA to celebrate the Juno spacecraft’s July 4th arrival at the planet Jupiter. Planetary scientists study outer space, while neuroscientists such as myself study inner space. But as my visit to JPL revealed, the goals and challenges of each discipline are far more similar than you might think. So, what is Juno, and how does its mission mirror that of many neuroscientists?Continue reading
