title: gamma-Aminobutyric acid concentrations in the cerebrospinal fluid of newborn infants.
abstract: gamma-Aminobutyric acid (GABA) concentrations in cerebrospinal fluid (CSF) were measured in 20 neonates with various gestational and postnatal ages. These concentrations varied between 9 and 45 nmol/ml which is approximately 20-100 times the concentrations found in adults. CSF GABA concentrations tended to decrease with advancing gestational age. No apparent alterations were noted with increasing postnatal age (until 6 weeks of age). Asphyxia but not neonatal sepsis was accompanied by an increase in CSF GABA concentrations compared to respective controls.
