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.


Time FliesFor 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.

    The days of thinking of time as a river—evenly flowing, always advancing—are over. Time perception, just like vision, is a construction of the brain.

    The shootings at Sandy Hook sparked debate ranging from gun control to bulletproof windows. But the most fruitful approach may be to prioritize our discussion of mental illness.
