ERPs were recorded by neuroscan system and analyzed to uncover the follow results. In normal group, ERPs in response to dynamic red stimulus were characterized by frontal positive amplitudes with a latency of about 180 ms and the peak latency of the late positive potential (LPP) in a time window between 290 and 580 ms. In abnormal group and singularly individual of normal group, ERPs in response to dynamic red stimulus were fully lost and characterized by vanished amplitudes between 0 and 800 ms. ERPs of two groups in response to dynamic green and blue stimulus were the same as ERPs of the normal group in response to red stimulus. In comparison with, ERPs of the two groups in response to static red, green and blue stimulus were not different, which were only characterized by a peak latency of LPP in a time window between 350 and 650 ms. Our results firstly pointed to the view that a novel phenomena that the above some subjects could not completely apperceive a sort of dynamic red stimulus by ERPs was observed and called \"dynamic red blindness\". Furthermore, our results also suggested that low-frequency ERPs induced by \"sustained moving\" maybe a good and new method for testing dynamic color perception competence.","PeriodicalId":169717,"journal":{"name":"Proceedings. 2005 First International Conference on Neural Interface and Control, 2005.","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117058531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generally, various researches on visual prosthesis are mainly focused on two solutions according to the research emphasis. One type is different designs surrounding the hardware circuitry, the other type is function evaluation and physiological test of artificial retina. On the one hand, there are probably three aspects, which are elementary structure, important factors of structure and biocompatible consideration. Among them, main structure generally consists of about three parts in theory. Moreover, it is claimed that other factors such as electrode-retina interface and pulse shape, should be taken into account. And the last is material, electrode shape and production technique. On the other hand, in order to demonstrate that epiretinal stimulation actually helps construct a visual prosthesis, functional evaluation and physiological test of the artificial vision is required. At present, researchers mainly used several kinds of animals for vitro biocompatibility tests and vivo biocompatibility tests. Besides that, there are novel alternative which researchers attempted to find. This paper will begin with general considerations related to all or most of retinal prosthesis, and then concentrate on the epiretinal electrical design. At the end of the paper an outlook of the possible trend of epiretinal electrical stimulation in future is presented.","PeriodicalId":169717,"journal":{"name":"Proceedings. 2005 First International Conference on Neural Interface and Control, 2005.","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127946979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each of them has its predominance. BIS is formed by the subparameters of EEG in time domain, frequency domain and bispectrum domain by means of a nonlinear function. The process to setup the function is very complicated. This implies that its stability is not very good. AEP index is rather reliable, but the monotone click stimulus would make patients dysphoric. So it's necessary to study the consistency and complementarity between BIS's subparameters and AEP index. This is just the goal of this paper. Based on the clinic requirement, we develop a new instrument to do research. The prototype instrument is composed of two parts: SCM module and PC. The SCM module is the heart of the hardware, in charge of stimulation and data acquisition, which evokes the auditory potentials, sampling the EEG and AEP signal and communicating with PC. The operating software on PC is designed by the virtual instrument workbench-Lab VIEW, and the signal processing is completed on Matlab. Experiment method: 10 rabbits, the anaesthetic is 3% pentobarbitol sodium, the dosage is 0.5, 0.25, 0.25, 0.25ml/kg, the interval is 20 minutes, EEG and AEP is recorded 5 minutes after every injection. Then EEG and AEP is recorded with the interval of 10 minutes after the last injection, and total number is 3. Result: After the signal processing, it turns out that the consistency between BIS subparameters and AEP index is rather good.","PeriodicalId":169717,"journal":{"name":"Proceedings. 2005 First International Conference on Neural Interface and Control, 2005.","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114653150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A whole set of system is divided into three functional parts including EEG conditioning, wireless transmitting and power supply management, link three pieces of circuit together through connector. The EEG conditioning part consists of two analogue circuit modules, one for each channel of EEG. In general, each analogue circuit module carries out differential amplification, active low-pass and high-pass filtering, dc level adjustment and output amplification. The wireless transmitting part includes RF chip and EEPROM used in program store. Battery and power supply management part is composed of li-ion regulator and protection circuit, voltage monitor and power supply management circuit. In this paper, the development strategy of three functional parts is described respectively. In addition, in order to investigate system performance of gathering EEG signal, the test results were given for not only standard signal source with the same amplitude but different frequency but also actual spontaneous and evoked EEG signal. The test results showed that system could meet the demands in researching various kinds of routine EEG in laboratory.","PeriodicalId":169717,"journal":{"name":"Proceedings. 2005 First International Conference on Neural Interface and Control, 2005.","volume":"27 20","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113942041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
