Time perception
To understand the neural mechanisms of time perception, we combine psychophysical, behavioral, and computational approaches to address the relationship between the timing of perception and the timing of neural signals. We are currently engaged in experiments that explore temporal encoding, time warping, manipulations of the perception of causality, time perception in schizophrenia, and time perception in high-adrenaline situations. We use this data to explore how neural signals processed by different brain regions come together for a temporally unified picture of the world.

For a popular-science essay that lays out the mysteries of time perception, see my essay Brain Time (published in What's Next? Dispatches on the Future of Science. M. Brockman, Ed).
For a more detailed explanation of the how and why of our scientific approach, see our experimental questions.

Disinformation and "fake news"
Lately we've heard the concern about the ease with which disinformation spreads -- the problem of fake news. But is our era meaningfully different from previous eras?

Silicon Immortality: Downloading Consciousness into Computers
Well before we understand how brains work, we may find ourselves able to digitally copy the brain's structure and able to download the conscious mind into a computer. What are the possibilities and challenges?
