We are pleased to announce the latest update of the 3D Atlas of Neurological Surgery, featuring categories with many new 3D models concerning:

• Spine and Spinal Cord Anatomy: https://3datlasofneurologicalsurgery.org/anatomy/spine-bone-anatomy
• Surgical Approaches to the Spine & Pedicle Screw Insertion Techniques (new category - Approaches/Spine)
• Lower Limb Peripheral Nerve Anatomy: https://3datlasofneurologicalsurgery.org/anatomy/peripheral-nerve-anatomy/lower-extremity-peripheral-nerves-anatomy-2

• Autochthonous muscles anatomy and fascial planes dorsal muscles - https://3datlasofneurologicalsurgery.org/anatomy/paraspinal-muscles/autochthonous-muscles-anatomy-and-fascial-planes-dorsal-muscles
• This update has been made possible through the collaboration with the Department of Neurosurgery, Medical Faculty & University Hospital Düsseldorf, Heinrich Heine University Düsseldorf, and the generous support of the Institute for Anatomy I, Medical Faculty & University Hospital

We would like to thank Prof. Jan Frederick Cornelius, PhD, Michael Wolf-Vollenbröker, MD, for their invaluable contributions in creating this material, and to Prof. Svenja Caspers for the institutional support.

We are also grateful to the European Association of Neurosurgical Societies (EANS) and to all our contributors who continue to support the mission of keeping this platform open-access for the neurosurgical community.

We are proud to announce the launch of the 3D Neuroanatomy Helper AI v0.1— a specialized AI assistant, based on customized ChatGPT created to support students, neurosurgery residents, educators, and professionals in understanding the complex field of neuroanatomy. The assistant is integrated with the 3D Atlas of Neurological Surgery database search tool, where you can explore the anatomical structures of interests after each reply from the chatbot.

The custom GPT is set to provide information on normal anatomy only, without any clinical correlations and treatment suggestions. However, it provides detailed, university-level anatomical descriptions of brain or neuroanatomical structure, explains morphology, spatial relationships, embryological development, and histology  ...
