| Abstract: | Changes in neurons and nerve fibers of the spinal cord at the level C4–C5 were studied in rats exposed to asphyxiain utero and killed at different times. In the first 10 days the changes in the nerve cells progressed gradually. By the age of 1–2 months the state of most neurons is back to normal, but in each hundred fields of vision pathologically changed neurons are found, mainly in zones of the collateral circulation. Changes also are observed in the nerve fibers.Laboratory for the Study of Brain Development, Scientific-Research Institute of Pediatrics, Academy of Medical Sciences of the USSR, Moscow.
