System Development Of Morris Experiments For Brain Function Evaluation

Morris Water Maze (MWM) is a device in which rats learn to escape from opaque water onto a hidden platform. The brain function, like memory ability is evaluated by analyzing the time and distance spent in finding the hidden platform. It’s widely used in medical science, biology, etc. Though there are many design scheme, this experimental design has its own advantages, compared to the other system. The major work of this article is listed as follow:Based on the research of this experiment’s theory and technique, a system using a programmable language Lab VIEW is designed with digital camera、computer and image acquisition card. The system can save and analyze data from the experiment with more functions、 lower cost、precisely. In addition, the user could add new parameters and index.Firstly, to reduce the experimental costing, this system uses the image acquisition card typed SDK2000, other than the one NI corporation produced that has high price. This ensures the high accuracy and the easy operation, and at the same time provides the basis for mass production of equipment and low the budget of scientific research. So it has high popularizing rate.Secondly, some of the existing index can not meet the request with the time goes on, so this experiment add some new parameters and index to analyze the experimental results and estimate the brain function more comprehensively, like vibration.Finally, with the science and technology developed, based on LabVIEW programming language, it’s very easy to upgrade the software, expand the system function or to use it by connecting with other experimental equipment.In brief, this experimental device improve the defect of other same ones, and at the same time, posses its own feature and advantage, and has high applied value and vast prospect.
