A new framework for consciousness is introduced based upon traditional artificial neural network models. This framework reflects explicit connections between two parts of the brain: one global working memory and distributed modular cerebral networks relating to specific brain functions. Accordingly this framework is composed of three layers,physical mnemonic layer and abstract thinking layer,which cooperate together through a recognition layer to accomplish information storage and cognition using algorithms of how these interactions contribute to consciousness:(1)the reception process whereby cerebral subsystems group distributed signals into coherent object patterns;(2)the partial recognition process whereby patterns from particular subsystems are compared or stored as knowledge; and(3)the resonant learning process whereby global workspace stably adjusts its structure to adapt to patterns' changes. Using this framework,various sorts of human actions can be explained,leading to a general approach for analyzing brain functions. 相似文献

INTRODUCTION In the theory of partial differential equations,Schwartz distribution theory and Sobolev spacesplay a very important role. But one shortcoming ofdistribution theory, however, is its inability to solvenonlinear problems because the product of distri-butions may not be a distribution. The need to de-fine the product of distributions also arises withproblems in Dirac’s quantum theory of an elec-tromagnetic field. It is impossible to introduce anassociate multiplication i… 相似文献

路在何方——由《现场》九年历程透视民生新闻的发展方向 总被引:1,自引:0,他引:1
民生新闻以其内容贴近生活、表达方式自然亲切在电视新闻竞争中脱颖而出,然而,在日后的节目制作中,不约而同地出现了选题雷同、表现方式陈旧的尴尬.民生新闻走到今天,势必要重新思考、重新定位,走出一条崭新的道路.本文以福建省广播影视集团电视新闻频道的重点民生新闻栏目<现场>为分析对象,梳理九年来该栏目的发展和定位,从中探寻未来民生新闻在选题、节目制作等方面应遵循的轨迹. 相似文献
