The brain of an individual suffering from lissencephaly, a rare disorder in which the cerebral cortex fails to develop ridges and folds, resulting in much-diminished surface area.

The brain is part of a collection at the University of Texas and, although it is labelled with a reference number, all that is known of the original patient is that they were a resident of the North Texas State Hospital, and died in 1970. Their name and any other details of their condition and case history are lost. This photograph is one of a series of such pictures taken by Adam Voorhes.
