Jules Bernard Luys: from a description of the subthalamic nucleus to hypnotism

ABSTRACT The authors review the role of Jules Bernard Luys in the discovery of the subthalamic nucleus (STN) over 150 years ago. The relationships between the STN and movement disorders, particularly hemiballismus and Parkinson’s disease, are well known. The academic life of Jules Bernard Luys can be divided into two periods: a brilliant start as a neuroanatomist, culminating in the discovery of the STN, followed by a second period marked by a shift in his academic activity and an increased interest in topics such as hysteria, hypnotism and, eventually, esotericism.
