NORMAL COLLICULUS consists of densely packed nerve cells that
relay nerve impulses related to hearing originating in the structures of
the ear to the higher brain centers.
DAMAGED COLLICULUS from a monkey that was asphyxiated during
birth nearly five years previously is pitted by cavities (left
and right) left
by cells that disintegrated.
Pictures from the article Brain damage by asphyxia at birth, by William F. Windle in the October 1969 issue of the Scientific American, showing how the inferior colliculus is damaged by a brief period of asphyxia at birth. The legend under each picture is from the original article, p. 79.
