| pubmed-article:6584309 | pubmed:abstractText | A combination of light emitting diodes, as light sources, and optical fibers, as channels for the emitted light to form patterns, has resulted in a pattern reversal stimulator that is miniature in size, has pattern color options, is low in power requirements, and hence in possible stimulus artifacts. In addition, the use of optical fibers enables better separation of pattern elements and easier focusing on the pattern. The stimulator incorporates all the assets of previous versions of miniature pattern stimulators, is comparable or even less in price, and can interface with commercial averagers. | lld:pubmed |
