| Abstract: | In this paper, a system with two linked computers for visual evoked potentials(VEP) testing is discussed. One of the linked computers produces various stimulus patterns while the other collects and processes data. Some additive procedures provide the simultaneity of data sampling and "On"/"Off"signals of the stimulus patterns. The experimental results are similar to those obtained from the commonly used VEP system. However,being distinct from the common VEP system, this system with two linked computers can flexibly produce a great deal of stimulus patterns. It is a cheap, convenient and nexible VEP experimental system. |
