The relation of dehydration of the brain to the spreading depression of Leão.

摘要: Abstract 1. Spreading cortical depression does not involve the radiation endings of lateral geniculate fibers in striate cortex. 2. The reaction cannot be elicited by electrical stimulation cortex cat if exposed brain is covered with mineral oil to a depth 2 4 mm. 3. can regularly cat's internally dehydrated intravenous administration 90 per cent sucrose. 4. dehydration experiments, as well other evidence, suggest that impairment pia-arachnoid function necessary condition for spreading depression. 5. Arguments are advanced support hypothesis dependent on an abnormal neurohumeral reaction. 6. No evidence specific “suppressor” areas was found cat.
