A human twin study was undertaken to research the heredity of the EEG. The accuracy of the twins zygosity diagnosis was more than 98 per cent. Thirteen pairs of monozygotic twin had an intraclass correlation of 0.43 in alpha frequency and 0.65 in alpha sequence time per minute, and twelve pairs of dizygotic twins had an intraclass correlation of 0.20 and 0.34. Their hereditability was estimated by three methods as 29-58 per cent and 47-66 per cent, respectively.
