title: [The role of genotype and environment in shaping the interindividual variability of brain potentials related to movement].
abstract: By twins method (25 pairs of monozygotes and unisexual dizygotes of 18-30 years of age) the movement related brain potentials (MRBP) were studied during simple voluntary pressing of the button without any external signal (1), in situation of prognosis of two equally probable signals (2) and of prognosis of signal with probability 1.0 (3). Estimation of intrapair likeness of the amplitude-temporal parameters of MRBP, of conditioned-negative wave and of P300 (the two last are recorded in situations 2 and 3) showed that amplitude parameters are more influenced by the genotype than the temporal ones; in situations 2 (more frequently) and 3 a greater number of properties, than in the situation 1, depends on the genotype.
