Wonder about the latest research on how the brain works? You can tune in now to the June 6 Web stream of Technology Day, the intellectual centerpiece of Tech Reunions 2009. After remarks by President Susan Hockfield, three MIT faculty share their research from 9 a.m. until 12:45 p.m. EDT.

How the Brain Invents the Mind—Rebecca Saxe PhD ’03, Cognitive Neuroscience

When you look at other people, the features visible on the outside are only a small part of what you perceive. Many people are much more interested in seeing, or inferring, what’s going on inside: other people’s thoughts, beliefs and desires. How does the brain—an electrical and biological machine—construct abstract thoughts?

Indeed, no computer system even comes close to this level of proficiency. How do people acquire these impressive visual skills?

Can researchers ever understand what happened in human evolution well enough to build a truly intelligent machine?
