Dear Colleagues, dear friends,

we would like to warmly welcome you once more to the bi-annual

3rd Psychiatric Surgery Summit (PSS2026)

The PSS is a working meeting bringing together experts in the field of Deep Brain Stimulation (DBS), ablative surgery and non-invasive stimulation technology in the psychiatric indications. We will again meet for two and a half days of intense and in depth discussion about this burgeoning field. Internationally renowned faculty from the fields of Psychiatry, Neurology, Neurosurgery, Neurophysiology, Engineering and more will give in depth overview on their work and there will be ample time for discussion.

PSS2026 is intended for Psychiatrists, Neurologists, Neurosurgeons, Neuroscientists, DBS staff and graduate students. It is a HYBRID-meeting for working and discussion. This meeting is held on a biannual basis. Registration will be performed on a first come first serve basis.

We are very much looking forward to seeing you in Freiburg in fall of 2026, on site or online, so make sure you mark the time in your calendars. SAVE THE DATE: 22-24 October 2026!
The meeting is endorsed by the ESSFN and WSSFN.
