The eerie images were found in a disused basement of Yale University in Connecticut, which also happened to contain hundred of brains preserved in jars of formaldehyde.
It was determined that the collection of images belonged to pioneering brain surgeon Dr Harvey Cushing, who left the his impressive collection of photos and patients’ brains to the university upon his death in 1939.
The photos show several different patients either before or after brain surgery, yet most of their identities are unknown.
