报告人简介: Dr. Barry E. Stein is professor and chairman in Department of Neurobiology and Anatomy, Wake Forest School of Medicine, Winston-Salem, NC. He got his Ph.D. in Neuroscience in City University of New York in 1971 and received his postdoctoral training at the University of California Los Angeles. He started his career as an assistant professor in Medical College of Virginia/Virginia Commonwealth University in 1975 and was promoted to associate professor in 1977 and professor in 1982. In 1994, he moved to Wake Forest School of Medicine and became chairman in department of neurobiology and Anatomy till now. Dr. Stein was the author of nearly 200 papers published in peer-reviewed journals such as Science, Nature, PNAS, etc and wrote/edited 36 books. His research interest is to understand the neural basis by which the brain is able to integrate information from multiple senses.
报告内容简介: A remarkable feature of the brain is its ability to synthesize information from different senses to detect, identify, and localize external events. This process of “multisensory integration” is unconscious, and takes place in multisensory neurons in many locations in the brain. However, this process has been studied most intensely in the midbrain superior colliculus (SC) because of its high incidence of such neurons and their direct link to overt behavior (attentive/orientation). Three sensory representations (visual, auditory, somatosensory) are present in the SC, with neurons exhibiting all cross-modal convergence patterns. These neurons respond to cross-modal stimuli derived from the same event with striking enhancements in activity, thereby increasing the likelihood of SC-mediated behaviors. However, the circuitry underlying these integrative abilities must be formed during postnatal life. Its formation involves extensive interactions between the SC and association cortex that are based on cross-modal experiences. The protracted nature of this maturational process ensures that the operational features of multisensory integration are well adapted to the environment in which it will be used. The development and experiential factors involved in this process, as well as the applicability of this model to human perception and behavior will be discussed.
