[Pattern reversal VEP in TV and moving-mirror stimulation: a methodological comparison]. / Musterumkehr-VEP bei TV- und Drehspiegelreizung: ein methodischer Vergleich.

Pattern-Reversal visual evoked potentials (VEP) were elicited in 10 controls by optomechanical and TV-reversal. TV-stimulation was done in the frame-locked and -unlocked mode. Comparing P2-latencies evoked by different stimulation fields of the screen delays up to 30 ms and increased standard deviations could be observed in the TV-stimulation modes. Moreover, stimulating with small checks a diminution of amplitudes and a simplification of the shape was seen in contrary to the mirror method.
