In the average adult human, the brain represents about 2% of the body weight. Remarkably, despite its relatively small size, the brain accounts for about 20% of the oxygen and, hence, calories consumed by the body (1). This high rate of metabolism is

Adenosine A2areceptor antagonists reduce symptom severity in Parkinson disease (PD) and animal models. Rodent studies support the hypothesis that A2aantagonists produce this benefit by reducing the inhibitory output of the basal ganglia indirect path

✓ Between 1982 and 1990, a series of 31 children with craniopharyngiomas underwent initial surgery at the Children's Hospital of Philadelphia with an attempt at total tumor removal. Nine (29%) of them were found to have fusiform dilatation of the s
