Abstract
Comparative analysis of EEG tracings of identical and fraternal twins between 6 and 30 years of age by Vogel (1958) revealed a much greater similarity among the homozygotic pairs than among the heterozygotic partners. Conjoined twins are identical twins. In addition to the same set of genes, they may pool their blood circulation by multiple anastomoses. Such was the case in a 7-year-old pair reported by Ian Hay Brown (1959). Sometimes both hearts are intimately fused and seem to beat at the same rate (Johnson and Doherty 1957). Brown observed in his living thoracopagi a simultaneous heart rate at one time and recorded a separate EKG rhythm at other times. The question arose whether brain wave activity in conjoined twins in addition to a high degree of similarity also may show an unusual amount of synchrony in the EEG tracings. Thoracopagus conjoined girls were born on June 29, 1959, inKeywords
