Stereotactic biopsy for brainstem lesion: Comparison of approaches and reports of 10 cases [PDF]

, 2011
BackgroundStereotactic biopsy for brainstem lesion offers high diagnostic yield with low morbidity. We compared two modalities of biopsy procedure, frame-based and frameless stereotaxy, either transfrontal or transcerebellar route.

Acute and chronic gene expression activation following medial forebrain bundle DBS and selective dopamine pathway stimulation

Scientific Reports
Deep brain stimulation (DBS) of the medial forebrain bundle (mfb) demonstrated anti-depressant effects both clinically and experimentally. Modulation of mesocorticolimbic dopaminergic (DA) activity could contribute—in part—to the therapeutic effects.

Cognitive and Emotional Determinants of Subthalamic Oscillations During Freezing While Turning in Parkinson's Disease

European Journal of Neuroscience, Volume 63, Issue 11, June 2026.
In 13 individuals with Parkinson's disease, subthalamic nucleus theta power (4–8 Hz) during turn‐induced freezing of gait was positively associated with anxiety severity and negatively associated with cognitive performance, while no such associations were found during effective turning.

Pseudoaneurysms as a complication of stereoelectroencephalography: Case series and clinical recommendations

Epilepsia, Volume 67, Issue 3, Page 1193-1205, March 2026.
Abstract Objective Stereoelectroencephalography (sEEG) is commonly employed in the workup for epilepsy surgery in patients with focal drug‐resistant epilepsy (DRE). Intracranial hemorrhage is a known complication, with reported incidence rates ranging from .9% to 19.1%. Rarely, pseudoaneurysms have been reported in literature as a potential cause. This

Correlation of the CT Compatible Stereotaxic Craniotomy with MRI Scans of the Patients for Removing Cranial Lesions Located Eloquent Areas and Deep Sites of Brain [PDF]

, 2015
The first goal in neurosurgery is to protect neural function as long as it is possible. Moreover, while protecting the neural function, a neurosurgeon should extract the maximum amount of tumoral tissue from the tumour region of the brain.
