  • Title: [The role of the genotype in the variability of human evoked potentials at different stages of ontogeny].
    Author: Mariutina TM.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1992; 42(4):636-44. PubMed ID: 1332281.
    Abstract:
    The determinants of individual differences in visual EPs to stimuli of different type depending on the age of subjects were studied. EPs to flash, checkerboard pattern and some other stimuli with semantic aspect were recorded in three groups of MZ, DZ twins aged 8-9, 10-12, 18-25 years. The heritability of EPs parameters is not ontogenetically stable characteristic. It changes from one age group to another in different way for separate EPs components and parameters depending on their nature, type of stimulus, area of recording. Most of all genotypical influences are manifested in EPs parameters of 10-12 years old subjects, especially the middle latency components from vertex area and latent periods of EPs in comparison with their amplitudes.
