Conjunctive population coding integrates sensory evidence to guide adaptive behavior Open
Cognitive flexibility relies on the continuous accumulation and integration of sensory evidence to guide adaptive behavior. In natural environments, behaviorally relevant information unfolds sequentially over time and is constantly evaluat…

Aperiodic Activity Reflects Pathologic Waveform Shapes in Focal Epilepsy Open
Epilepsy constitutes a clinically manifest excitability disorder that is characterized by aberrant electrophysiological activity in the electroencephalogram (EEG). The correct identification of the seizure onset zone relies on the visual d…

Exploring Tumor Size as a Predictor of Treatment Success/Failure Following Stereotactic Radiosurgery in Vestibular Schwannoma Open
Objective: Stereotactic radiosurgery (SRS) achieves high tumour control in vestibular schwannoma (VS), yet treatment failure occurs in a subset of patients. Tumour size is a proposed predictor, but prior studies show conflicting results an…

Voxel-based evaluation of hemorrhage risk in brain biopsies Open
Objective While technological progress increases precision and reduces invasiveness of stereotactic brain biopsies (BB), biopsy related hemorrhage (BBH) is still a key risk. This study identifies risk factors and uses voxel-based lesion sy…

The Silent Transformation of Stereotactic Brain Biopsies After the Introduction of Robotics Open
Background In frame‐based stereotaxy, the design of the frame limits trajectory selection, e.g., to the temporal lobe and posterior fossa. We hypothesise that frame‐less neuronavigation and robotic technology might have expanded these ster…

Surface Electromyographic Features for Severity Classification in Facial Palsy: Insights from a German Cohort and Implications for Future Biofeedback Use Open
Facial palsy (FP) significantly impacts patients’ quality of life. The accurate classification of FP severity is crucial for personalized treatment planning. Additionally, electromyographic (EMG)-based biofeedback shows promising results i…

Connectome-based disentangling of epilepsy networks from insular stereoelectroencephalographic leads Open
Objective Epilepsy is considered as a network disorder of interacting brain regions. The propagation of local epileptic activity from the seizure onset zone (SOZ) along neuronal networks determines the semiology of seizures. However, in hi…

Sex-specific difference in treatment success/failure after vestibular schwannoma treatment Open
Background Sex-related differences in patients with sporadic, unilateral vestibular schwannoma (VS) are poorly investigated so far, and it remains unclear whether biological sex affects treatment response to stereotactic radiosurgery (SRS)…
View article: New-onset facial spasm is associated with treatment failure after radiosurgery in vestibular schwannoma
New-onset facial spasm is associated with treatment failure after radiosurgery in vestibular schwannoma Open
Background New-onset facial spasm (NOFS) has been reported to be a post-therapeutic side effect, when treating vestibular schwannoma (VS) with radiosurgery (SRS) and has been linked to post-treatment pseudoprogression. The aim of this stud…

Strong connectivity to the sensorimotor cortex predicts clinical effectiveness of thalamic deep brain stimulation in essential tremor Open
Clinical effectiveness of DBS for ET corresponded to a distributed connectivity profile, with the connection to the sensorimotor cortex being most relevant. Long-term follow-up in larger cohorts and replication in out-of-sample data are ne…

Innovative mobile app solution for facial nerve rehabilitation: a usability analysis Open
Background Facial palsy after vestibular schwannoma surgery is temporary in many cases but can significantly affect patients’ quality of life. Physical training—initially guided and subsequently performed by the patient—is of paramount imp…

Cystic vestibular schwannoma – a subgroup analysis from a comparative study between radiosurgery and microsurgery Open
Some vestibular schwannoma (VS) show cystic morphology. It is known that these cystic VS bear different risk profiles compared to solid VS in surgical treatment. Still, there has not been a direct comparative study comparing both SRS and S…

Intermittend pneumatic venous thrombembolism (VTE) prophylaxis during neurosurgical procedures Open
Background The management of perioperative venous thrombembolism (VTE) prophylaxis is highly variable between neurosurgical departments and general guidelines are missing. The main issue in debate are the dose and initiation time of pharma…

Defining benchmark outcomes for mesial temporal lobe epilepsy surgery: A global multicenter analysis of 1119 cases Open
Objective Benchmarking has been proposed to reflect surgical quality and represents the highest standard reference values for desirable results. We sought to determine benchmark outcomes in patients after surgery for drug‐resistant mesial …

Outpatient care for facial palsy—a survey on patient satisfaction in uni- and interdisciplinary approaches Open
Objective The various causes of facial palsy, diagnostic methods and treatment approaches frequently involve different medical specialities. Nevertheless, there exist only few specialized consultation and therapy services for patients with…

Predictive value of facial motor–evoked potential and electromyography for facial motor function in vestibular schwannoma surgery Open
Purpose Intraoperative neuromonitoring (IONM) aims to preserve facial nerve (FN) function during vestibular schwannoma (VS) surgery. However, current techniques such as facial nerve motor evoked potentials (FNMEP) or electromyography (fEMG…
