Fourier-analysed steady-state VEPs in pre-school children with and without normal binocularity.

摘要: Pre-school children aged 4–5 were examined with steady-state VEP in response to a sinusoidal grating pattern spatial frequency of 4 c/deg, reversing at rates 5, 10, and 15 Hz. Normal (n = 10) compared subjects lacking stereo perception 6) showing significant unilateral amblyopia visual acuity the worse eye <0.5 7). Fast Fourier Transform was used for analysis crude responses. Compared normals, showed significantly lower power second harmonic evoked by binocular stimulation gratings reversed The amblyopic group difference between dominant non-dominant regarding first responses 5 10 These findings are discussed relation magnocellular parvocellular pathways suggested models linear non-linear processing signals.
