Abstract:
Steady-state VEPs responses (pattern reversal stimulation) have been studied by the application of frequency analysis with Fourier methods. Authors examined with this method a group of children aged from 4 to 12 years, without ophthalmological or neurological pathologies. Responses evaluation is based on the number of harmonic frequency components and also on the power spectra of the first two components. Frequency analysis shows a well proportioned responses development that can be considered as a good index of visual function growth.
