  1. Obstructive hydrocephalus animals showed statistically significant elevations of the epidural ICP day 1 after kaolin injection compared to control animals. At day 7 the epidural ICP was measured before intraventricular cannulation and then simultaneously with the ventricular ICP to compare the two recording sites. Comparison ****p < 0.0001
