The Food and Drug Administration (FDA) approved Deep brain stimulation DBS as a treatment for essential tremor in 1997, for Parkinson's disease in 2002, dystonia in 2003, and obsessive-compulsive disorders, in 2009. DBS is also used in research studies to treat chronic pain, PTSD, and has been used to treat various affective disorders, including major depression; neither of these applications of DBS have yet been FDA-approved. While DBS has proven effective for some patients, potential for serious complications and side effects exists.

Foley et al. 1) first reported lumbar discectomies through an endoscopically visualized tube in 1997.

Vagus nerve stimulation for drug-resistant epilepsy was first approved in Europe in 1994 and in the United States (US) in 1997.

In 1997, Morel, Magnin, and Jeanmonod presented a microscopic stereotactic atlas of the human thalamus. Parcellations of thalamic nuclei did not only use cyto- and myeloarchitectonic criteria but were additionally corroborated by staining for calcium-binding proteins, which bears functional significance. The atlas complies with the Anglosaxon nomenclature elaborated by Jones and the data were sampled in three orthogonal planes in the AC-PC reference space 2).

Simultaneous PET/MRI detection was first demonstrated in 1997, however, it took another 13 years, and new detector technologies, for clinical systems to become commercially available.

Interhemispheric acute subdural hematoma was first described by Aring and Evans 3) in 1940 and only about 100 cases have been reported till 1997 4) 5) 6).
