The goal of this study was to develop two computer-controlled visual evoked potential (VEP) stimulators. The first device employs a 12 x 12 matrix of 5 mm square Light Emitting Diodes (LEDs) and is housed in an 8 x 8 utility box structure. The second device employs two 8x8 matrices of 3 mm square LEDs, each housed in one eyepiece of a goggle-like structure. A quantitative comparison of the performance of these stimulators was carried out in terms of absolute and interpeak latencies, signal-to-noise ratio (SNR) and cross-correlation between sequential responses obtained from them. Six normal adult subjects were involved in the comparison. Data were acquired from monocular full-field stimulation. The comparison emphasizes potential advantages of the newer, goggle- mounted stimulator.
