For the human-level intelligence simulation we should simulate it from the essence of intelligence and with the research results of brain science  cognitive science  artificial intelligence and others. In our study  a mental imagery knowledge representation mode had been established based on cognitive mechanism of human. Two kinds of table named mental imagery concept attributes table and concept attribute value ranges table had been used together to represent mental imagery knowledge in system. Mental imagery concept attributes table which formed by the thought of concept lattice was used to decide relations among concepts and attributes under the circumstance of coarse granularity. While concept attribute value ranges table was used to record differences of individual objects belong to the same concept under the circumstance of fine granularity. The concrete structured method of tables and decision-making process of system were described in the paper. Finally  the validity and feasibility of the knowledge representation mode are illustrated with real examples. 2009 Springer Berlin Heidelberg.

In this paper  in order to be more sensitive to the volumetric changes of capillaries in the skin  the photon propagation process in human brain tissue and skin tissue with various source and detector separation distances were simulated based on the Monte Carlo method. The human brain model and the skin model that were used in our experiments have five layers and seven layers  the separation distance of source and detector should be approximately eight millimeters. Future work was discussed at the end of the paper. 2009 IEEE.  respectively. The backscattered intensity from every layer of the human tissue model was obtained by marking the deepest layer that every photon can reach. The simulation results of brain model indicated that the source-detector separation distance should be selected at three centimeters for studies on the actions of the brain nerve cells
