Objective: Non-invasive assessment of hemispheric language dominance by functional MRI (fMRI) is of great clinical interest e.g. for planning of epilepsy or brain tumour surgery in potentially language-eloquent localization, but still remains challenging. Clustered sparse acquisition can improve language[for full text, please go to the a.m. URL], 72.

Objective: Assessing the cortical representation of language in the individual patient, e.g. by means of repetitive transcranial magnetic stimulation (rTMS), is of high importance in the preoperative context. We could recently show that rTMS with a frequency of 30 Hz is superior to the most commonly[for full text, please go to the a.m. URL], 72.

Objective: Degenerative cervical myelopathy (DCM) shows growing prevalence in industrial nations due to the demographic development. However, the surgical decision-making is still challenging due to the lack of sufficiently reliable predictors of disease progression and surgical outcome. Recently, the[for full text, please go to the a.m. URL], 72. Jahrestagung der Deutschen Gesellschaft für Neurochirurgie (DGNC), Joint Meeting mit der Polnischen Gesellschaft für Neurochirurgie

Objective: The assessment of neurocognitive functions in brain tumour patients suffers from the limited availability of sensitive and validated intruments to detect even slight or moderate impairments. The Bells cancellation test is most widely used for assessing neglect in brain tumour patients but[for full text, please go to the a.m. URL], 71.

Objective: Due to its relative simplicity in comparison to other verbal learning memory tests (VLMT) the revised Hopkins VLMT (HVLMT-R) is used most often for the assessment of brain tumour patients. The German version of the HVLMT-R consists of a translation of the original English HVLMT-R, using exactly[for full text, please go to the a.m. URL], 71.

Objective: Picture naming is the most widely used task for language mapping in the context of neurological surgery but requires a high level of expertise from the investigator and is highly observer-dependent. Moreover, online-analysis of language errors is challenging, whereas offline video-analysis[for full text, please go to the a.m. URL], 70.

Objective: Task-locked navigated transcranial magnetic stimulation (nTMS) allows for direct investigation of cortical functions in the stimulated area by analyzing behavioural changes during the period of train duration. Using short stimulation trains like paired-pulse (PP) nTMS instead of the commonly[for full text, please go to the a.m. URL], 70.

Objective: In this study, we aimed at a specific characterization of the association between cognitive decline and damage to white matter fiber bundles in patients with a glioblastoma multiforme (GBM) before treatment. Since the callosal body (CB) is an important anatomical substrate for cognitive function,[for full text, please go to the a.m. URL], 70.

Objective: Achieving a high test-retest reliability when mapping language regions by functional MRI (fMRI) is highly relevant for clinical applications like presurgical mappings. We, therefore, systematically tested the short- and long-term fMRI-reliability in a group of healthy subjects, using a picture[for full text, please go to the a.m. URL], 69.

Objective: Repetitive transcranial magnetic stimulation (rTMS) to map cortical language functions by inducing “virtual lesions” during task performance (e.g., picture-naming) has recently been introduced into pre-surgical diagnostics in brain tumor patients. We investigated to which extent[for full text, please go to the a.m. URL], 68. Jahrestagung der Deutschen Gesellschaft für Neurochirurgie (DGNC), 7.

Objective: Navigated repetitive transcranial stimulation (rTMS) represents a rather novel approach to depict highly language-relevant cortical sites non-invasively. Due to low specificity and considerable painfulness when stimulating with the commonly used 5-10 Hz rTMS, rTMS-language-mapping is still[for full text, please go to the a.m. URL], 67.

Objective: In contrast to high-grade gliomas (HGG) with their infiltrative growth pattern, brain metastases (MET) are usually regarded as well delineated tumours. Surgical resection may thus be supported more often for MET in eloquent localizations than for HGG. The objective of this study was to compare[for full text, please go to the a.m. URL], 67.
