报告人简介: J. David Dickman Ph.D, Professor and Vivian L. Smith Endowed Chair, Department of Neuroscience, Baylor College of Medicine; Neuroscience Program Director, Rice University. Member of Society for Neuroscience; Member of Association for Research in Otolaryngology; Member of Royal Institute of Navigation. His research focuses on understanding the neural bases of vestibular information processing and magneto reception in spatial orientation and navigation.
报告简介：It has been known for several decades that many animals can use the Earth Magnetic Field for spatial orientation and navigation functions. The mechanisms of magnetic field transduction and the neural correlates that contribute this amazing sense are only beginning to be investigated. We have identified neurons in the pigeon brain that encode magnetic field direction, intensity, and polarity that can be used for orientation and possible maps of earth location. Recent work has shown these neurons are multisensory and encode magnetic space in allocentric Earth fixed coordinates. We have also traced the flight patterns of pigeons and using GPS and found that they appear to follow a magnetic memory signature of their navigation routes.
