Cardiac Arrest Encephalopathy:
Damage restricted to the brainstem is only seen after total interference
with aerobic metabolism occurs; Janzer and Friede (1980) referred to
brainstem pathology as "cardiac arrest encephalopathy;" this was the
case in monkeys subjected to several minutes of total asphyxia at birth.
Myers (1972) found that prolonged partial hypoxia late in
gestation caused damage to wide areas of the cerebral cortex,
which was thought far more important that the brainstem pattern.
This was cerebral palsy!
Miller and Myers (1970, 1972) found also that adult monkeys
sustained brainstem damage with complete circulatory arrest, and
widespread cortical damage with partial circulatory insufficiency.
