Stephen L. Macknik

Stephen L. Macknik serves as Professor of Ophthalmology, Neurology, and Physiology & Pharmacology at SUNY Downstate Health Sciences University's College of Medicine. His laboratory, co-directed with Susana Martinez-Conde, investigates fundamental mechanisms of visual perception and their clinical applications in neurological disorders.

His educational background includes:

• PhD in Neurobiology from Harvard University (advised by Margaret Livingstone)
• Postdoctoral Fellowship at Harvard Medical School (with David Hubel)
• Postdoctoral Fellowship at Cold Spring Harbor Laboratory (with Zachary Mainen)

Macknik's research centers on three interconnected domains: (1) The neurobiology of brightness/flicker perception through human/monkey psychophysics and physiology; (2) Advanced molecular imaging of abnormal blood flow in epilepsy, macular degeneration, and traumatic brain injury; (3) Neural links between attention, emotions, and autism/mood disorders. His work reveals how termination responses govern visual awareness and how microsaccades maintain perceptual stability, with significant clinical translation for Parkinson's and Alzheimer's diagnostics.

His publication history shows consistent focus on visual neuroscience, evolving from foundational studies on backward masking (1998-2000) to microsaccade mechanisms (2002-2013), with increasing clinical applications. Key trends include interdisciplinary integration of magic techniques for cognitive research, methodological innovation in eye-tracking diagnostics, and modular theories of visual awareness confined to occipital cortex.

Major recognitions include:

• EyeTrack Award for neurological disease diagnostics via eye movement signatures
• Prisma Prize for Best Book of the Year (2011) for Sleights of Mind: What the Neuroscience of Magic Reveals About Our Everyday Deceptions
• 2011 EyeTrack Prize–Tobii Technologies for progressive supranuclear palsy research

Macknik's advisory work includes collaborations with Ralph Adolphs (Caltech) and Dan Kennedy (Indiana University) on autism attentional processing, though specific advisees aren't listed. His laboratory develops advanced imaging techniques for neurological applications while maintaining strong theoretical contributions to visual neuroscience.

The Macknik-Martinez-Conde Laboratory pioneered the neuroscience of magic as research methodology, demonstrating how stage techniques exploit attentional limitations. Current work focuses on translating microsaccade signatures into clinical tools for early detection of neurodegenerative diseases and exploring blood flow dynamics in ophthalmological pathologies.
