The localization of a gene responsible for a normal variant of the human electroencephalogram to the distal part of chromosome 20q is reported. A linkage analysis, including 17 families with 191 individuals, tested with 73 RFLPs and 22 blood and serological markers, was performed for the low-voltage electroencephalogram. This is a normal variant of the(More)
This study investigated age-related changes in the human brain function using both traditional EEG analysis (power spectra) and the correlational dimension, a measure reflecting the complexity of EEG dynamics and, probably, the complexity of neurophysiological processes generating the EEG. Assuming that the accumulation of individual experience is(More)
Visually and auditory evoked EEG potentials were studied in 248 healthy university students, who were carriers of one of the following hereditary EEG variants: Monomorphic alpha-waves; low-voltage-EEG; EEG in which the alpha-rhythm was mixed diffusely with beta-waves; and EEG with fronto-precentral beta-groups. The study uncovered consistent and(More)
Heterozygotes of autosomal-recessive diseases can often be recognized by special heterozygote tests, since enzyme activities are normally reduced in comparison with the normal homozygote state. In Drosophila, the majority of recessive lethal mutations shows a reduction of fitness in heterozygotes, whereas in a strong minority fitness of heterozygotes is(More)

Sherman et al. (1984) concluded from a cytogenetic and genetic analysis of families with the marker (X) syndrome that the rate of the mutation leading to this syndrome is extraordinarily high (7.2 X 10(-4) in male germ cells), and that these mutations occur exclusively in male germ cells. It is shown by some model calculations that the empirical evidence(More)
The problem of localization of chromosomes in relation to each other in the interphase nucleus of human lymphocytes was investigated by analysis of chromatid and chromosome aberrations observed in lymphocyte cultures of three patients with Fanconi's anemia, one patient with Bloom's syndrome, and in Trenimon-treated (Trenimon, Bayer) normal cells.(More)
