Human right half brain has an advantage over the perception of local geometric properties, study says

the latest study by the National Key Laboratory of Brain and Cognitive Sciences of the Institute of Biophysics of the Chinese Academy of Sciences found that the left hemisphere of the human brain has the advantage of perception of the wide range of topological properties, and the right hemisphere has the advantage of the perception of local geometric propertiesThe findings were published in the Proceedings of the National Academy of Sciences on December 26, 2007 and are featured in the current issue's Guide book columnThe cognitive science and brain imaging team led by Academician Chen Wei of the Institute of Biophysics of the Chinese Academy of Sciences has created the theory of topological perception of "wide-ranging first", challenging the theory of "local first" which has dominated for half a century, emphasizing that the perceptual process is started by the unchanging nature of large-scale topology, which provides a new way of thinking for the study of the differences between the brainsYoung scholars such as Wang Bo applied the theory of topological perception of "wide-ranging first" to the study of asymmetry in the hemisphere of the brainAfter more than 6 years of extensive experiments, they systematically tested various topological properties (such as the number of holes, internal and external relationships, etc.) and other geometric properties (such as orientation, distance, size, symmetry, parallelity, linearity, etc.) and consistently revealed the dominant perception of the left-brain topology of the right-handed person; Some experts believe that the conclusion of the study "the upper-tempo nature of the left hemisphere perception is dominant, the right hemisphere local geometric nature of the perception of the dominant", to solve the vision of the left and right brain relations of various controversial issues to provide a unified theoretical framework, at the same time for the understanding of the brain, the development of the brain provides a basic scientific basisThe reviewer spent years in the Proceedings of the National Academy of Sciences noting that this is an important and confusing area that has been widely studied for many years; Chen and his group provide strong evidence that the topological nature of the whole range can be clarified, if not completely and sufficiently(Chen Yu, Tang Yu)
