| Popis: | 1. 1. Rhythmic 7–12/sec activities, in several ways simulating alpha activity of adults, was observed in 312 out of 717 EEGs of newborns. 2. 2. Newborns delivered with their heads positioned right occiput anterior, transverse, or posterior showed greatest amounts of alpha-like activity in right hemisphere leads, whereas infants born left occiput transverse or posterior showed greatest activity on the left. Compression of one hemisphere during birth may depress the electrical activity, the hemisphere at risk being determined by the position of the head. 3. 3. Infants born under circumstances which were potentially brain injuring, such as breech or cesarean section during labor, less often showed this alpha-like activity than infants born by uncomplicated vertex delivery or cesarean section performed before labor. 4. 4. No relationship between the Apgar index for asphyxia, or pre-delivery sedation given the mother, and alpha-like activity was observed. 5. 5. The Shepovalnikov hypothesis that a larval alpha rhythm already exists at birth deserves consideration, although further work is required to prove conclusively that the newborn alpha-like activity is not an artifact. |
