Scientists are attempting to map the wiring of the nearly 100 billion neurons in the human brain. Are we close to uncovering the mysteries of the mind or are we only at the beginning of a new frontier?

Imagine navigating the globe with a map that only sketched out the continents. That’s pretty much how neuroscientists have been operating for decades. But one of the most ambitious programs in all of neuroscience, the Human Connectome Project, has just yielded a “network map” that is shedding light on the intricate connectivity in the brain. Join leading neuroscientists and psychologists as they explore how the connectome promises to revolutionize treatments for psychiatric and neurological disorders, answer profound questions regarding the electrochemical roots of memory and behavior, and clarify the link between our upbringing and brain development.

A second doesn't always feel like a second—time can seem to slow down if you're riding a death-defying roller coaster, or speed up while you're having a night out on the town. But just what's going on inside our heads to skew our perception of time? Neuroscientists Lila Davachi, Dean Buonomano, David Eagleman, and Kia Nobre discuss findings from the latest scientific investigations into the intricacies of our internal clocks in "The Deceptive Watchman," a program in the Big Ideas series at the 2014 World Science Festival.
