Abstract

During sleep there is a two- to threefold increase in the incorporation of inorganic orthophosphate-32P into a chemical fraction of the brain of the 20-day-old rat. This increase is not in the lipids or nucleic acids, but is associated with an acid-labile phosphate entity of the tissue residue after extraction of these fractions and phosphorus-containing substances of low molecular weight.
