[Analysis of the time course in electroretinography potentials].
1. For isolating of electroretinographic oscillatory potentials (Ops) a method of algebraic polynomial approximation of the low-frequency course of the electroretinogram is described. 2. Using the described method of approximation in 16 subjects, the isolated Ops displayed peak-latencies by 1-2 ms shorter than using the Fast Fourier Transform and a time window. Moreover, the amplitudes of OP1 were by 20% and of OP2 by 6% higher.
