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 the laboratory is the study of microscopic blood flow driven by perception and awareness, and occurring during disease states
