Photo: The most extraordinary human brain ever?

We can only imagine what life was like for this person. He or she was a resident of what is now North Texas State Hospital, a mental health facility, and died there in 1970, but that’s all we know. While the jar containing the brain is labelled with a reference number, the microfilm containing the patient’s medical records has been lost.

Photographer Adam Voorhes spent a year trying to track down more information about this and nearly 100 other human brains held in a collection at the University of Texas, Austin, to no avail. The label on the jar states that the patient had agyria – a lack of gyri and sulci, the ridges and folds formed by the normally wrinkled cerebral cortex. This rare condition, also known as lissencephaly, often leads to death before the age of 10. It can cause muscle spasms, seizures and, as it vastly reduces the surface area of this key part of the brain, a range of learning difficulties.
