Thus instead of being synonymous with specific procedures per- formed at
the level of the basal ganglia, stereotaxis is in fact a general
diagnostic and therapeutic concept, which has as its aim the precise
three-dimensional representation of the patient's brain in its entirety.
This three-dimensional representation is based on anatomical, neuro-
radiological and other localizing information, the spatial integration

"anatomical" approach to the human brain and to the surgical management
of localized pathologic proces- ses. Literally, stereotaxis means
"orientation in space". Taken in this general sense, all surgical
procedures obviously should be stereo- tactic, at least in their
principle! Two of the main themes of our meeting, namely the topic of
the first day, "Surgery of Epilepsy" and that of the second
"Stereotactic Cerebral Irradiation" of small brain tumours correspond to
this evolution toward a global "whole brain" concept of stereotaxis. The
same philosophy inspired the scientific efforts of the stereotactic
group Introduction 3 of the Sainte Anne Hospital, under the leadership
of its promoter, Professor Jean Talairach. This is the reason why the
present Meeting is dedicated in honor of his scientific work.
