These responses are recorded non-invasively by placing the surface electrodes at the scalp, and observed as a reading on an electroencephalogram (EEG). This generated potential is smaller in amplitude compared to the EEG signal, which is in the range of 1 to 20μV compared to 1 to 100μV of the latter. The VEP signal has been widely used for the diagnostics of ocular diseases in patients having vision related problems. The main parameters that were considered for the diagnostics of these diseases are the amplitude and the latency values. This field of study is gaining interest from researches all over the world. Researches now are focusing on analyzing these electrical signals in time-frequency domain to extract more information. This paper is intended to give a brief review of the theory and techniques that has been used by the previous researches in analyzing VEP for the investigation of ocular diseases. 2014-05-04T21:25:09Z 2014-05-04T21:25:09Z 2011-12 Working Paper p. 123-127 978-1-4673-0099-5 http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6148720 http://dspace.unimap.edu.my:80/dspace/handle/123456789/34222 http://dx.doi.org/10.1109/SCOReD.2011.6148720 en Proceeding of The Student Conference on Research and Development 2011 (SCOReD 2011); IEEE Conference Publications |
