Brain metabolism after electroshock seizure in the neonatal dog: a [31P]NMR study.

In vivo [31P] nuclear magnetic resonance (NMR) spectroscopy disclosed that a 10 second electroshock seizure in oxygenated neonatal dogs produced prolonged alteration of brain phosphocreatine (PCr), inorganic phosphate (Pi), and lactate. The slow return of these metabolites to baseline may be related to lower endogenous stores of high energy phosphates, or less developed pathways for their regeneration.
