Lebedev (Михаил Альбертович Лебедев) is a Russian-born (1963) Neuroscientist known for his neurophysiological studies of cerebral cortex. Lebedev underwent undergraduate education at Moscow Institute of Physics and Technology, where he received a M.Sci degree in Physics of Living Systems in 1986. His diploma advisor was Victor Gurfinkel. Lebedev proceeded to work at Gurfinkel's laboratory (1986-1991) where he conducted studies in the field of human motor control. En 1991 he went to the USA to learn neurophysiological techniques of single-unit recordings from the brain of awake, behaving animals - the techniques pioneered by Edward Evarts. In pursue of this goal, Lebedev joined the laboratory of Randall Nelson at the University of Tennessee, Memphis, y, after conducting a series of studies of the primary somatosensory cortex, received a PhD degree in Neurobiology in 1995. He continued to study neurophysiology of somatosensory cortex with Mathew Diamond at SISSA, Italia (1995-1997). En 1997-2002 Lebedev investgated neuronal mechanisms of premotor and prefrontal cortex with Steven Wise at NIMH, Bethesda, Maryland. He currently works with Miguel Nicolelis at Duke University, where he applies multielectrode recording techniques to a range of neurophysiological problems, including brain computer interfaces. Lebedev's research of human motor control conducted in Russia includes studies of postural automatisms, Kohnstamm's phenomenon, neck reflexes, ischemic suppression of muscle fibers and effects of vibratory stimulation on posture and electromyographic activity (tonic vibration reflex). His neurophysiological research addresses cortical plasticity, neural oscillations, neural correlates of cognition and brain-computer interfaces. In the study of neuronal encoding of attention and memory in prefrontal cortex (Atención versus memoria en la corteza prefrontal), Lebedev and his colleagues challenged the working memory theory of prefrontal cortex. Lebedev and colleagues recently demonstrated cortical plasticity during operation of brain-machine interfaces.
