| Abstract: | The content of lipids in rat cortical tissue homogenate and fraction of neuronal nuclei was determined under normal conditions
and after picrotoxin-induced seizures. Changes in lipid composition of homogenate and nuclear fraction differed considerably.
In homogenate, the content of sphingomyelin, lysophosphatidylcholine, and total phospholipids increased, while the content
of free fatty acid remained unchanged; in the nuclear fraction the total phospholipid content decreased, while the concentration
of free fatty acids increased.
