Abstract


Visual system of humans and most mammals the most important channels of access to environmental information , the process of visual image information in the animal brain , however , is extremely complex , and that most of the process we are poorly understood . This article as Brain and Cognitive Sciences laboratory animal vision research experiments preliminary work , mainly to carry out the design and construction of the work of the the visual experimental platform acquisition technology based on the endogenous optical imaging and microelectrode array , expand the experimental study of animal vision for the next laid a good foundation for hardware and software . First of finishing and read a lot of literature , carefully research the research status and development of the visual system at home and abroad , and the physiology of the visual system based on the simple introduction . Then , according to the laboratory conditions , the authors designed the overall structure of the visual research platform hardware system to build a the visual experiment data acquisition system based on endogenous optical and microelectrode array two research means . The same time , the authors of visual stimulation and animal physiological state , maintaining and monitoring system to system design and construction , and proposed synchronized between systems solutions . Secondly , based on the research needs of the primary visual cortex , Cambridge graphical generate the system prepare specific visual stimuli graphics program . The program is mainly used for animal visual cortex neurons receptive field integration fields and functions to build observation. At the same time , the the endogenous optical data preprocessing links , based on a network of blood vessels extraction arteriovenous separation method , independent component analysis and clustering algorithm visual cortex . Finally , research on the visual system , the direction and goal of the next step .
