Stephen Macknik, PhD
Principal Investigator
Laboratory of Behavioral Neurophysiology

The Macknik laboratory is dedicated to studying the neural underpinnings of visual and sensory awareness and perception. A number of neurobiological techniques are employed so as to study the neural correlates of sensory experience, such as psychophysics (quantified measurements of behavior), electrophysiology of neuronal activity, and brain imaging such as functional magnetic resonance imaging and macroscopic as well as microscopic optical imaging. A special interest in our laboratory is the study of microscopic blood flow driven by perception and awareness and occurring in neurological disease.

Dr. Stephen Macknik received his PhD at Harvard University in the laboratory of Professor Margaret Livingstone. He went on to complete a postdoctoral fellowship with Nobel-laureate Professor David Hubel at Harvard Medical School, and also with Professor Zach Mainen at Cold Spring Harbor Laboratory. Dr. Macknik led his first laboratory at University College London, and has since moved on to lead the Behavioral Neurophysiology laboratory at Barrow Neurological Institute.

Dr. Macknik's research and scientific outreach activities have been featured in the New York Times, Time Magazine, The New Yorker, The Wall Street Journal, the Chicago Tribune, the Boston Globe, the Los Angeles Times, NPR, BBC, PRI, ABC News, Fox News, MSNBC, Nova: Science Now, the Times (London), and Der Spiegel, among hundreds of other media outlets. He is board member of Scientific American, where he has published several feature articles and for which he writes a column titled Illusions, and a free online blog called Illusion Chasers. His other publication credits include contributions to Nature, Nature Neuroscience, Neuron, Nature Reviews Neuroscience, and Proceedings of the National Academy of Science.
