Preoperative three-dimensional images with surface venous anatomy may be used in the planning of a linear scalp incision and the opening site of the dura mater for protection of surface veins during surgical dissection, and to find the splitting site of the brain according to the lesion. In 45 patients who had a brain tumor, linear scalp incision planning was done by regarding the three-dimensional images derived from post-contrast time-of-flight (TOF) sequence raw data. The findings of correspondence and the quality of routine contrast-enhanced magnetic resonance imaging (MRI) and three-dimensional volume rendering for tissues (VRT) images were analyzed separately with the surgical findings according to a visual grading system. Our experience revealed that the surgical findings correlated well with the three-dimensional VRT images. According to a visual surgical grading system, a grade III correlation was found in 20 (45%), grade II in 15 (33%), grade I in 7 (15%), and grade 0 in 3 (7%) patients in our study population. At the end of our research we conclude that this method is useful in terms of the preoperative determination of brain surface anatomy and may be used in the determination of the site of a linear scalp incision according to the localization of an intracranial lesion.

Selecting channels for motor imagery (MI)-based brain-computer interface (BCI) systems can not only enhance the portability of the systems, but also improve the decoding performance. Hence, we propose a cross-domain-based channel selection (CDCS) approach, which effectively minimizes the number of EEG channels used while maintaining high accuracy in MI recognition. The EEG source imaging (ESI) technique is employed to map scalp EEG into the cortical source domain.

Patients with localized scleroderma on the face typically exhibit asymmetrical linear or patchy skin lesions and indentations on areas such as the scalp and forehead, with a smooth, waxy surface. In the early stages, medication is used to control the progression of the disease. In later stages, plastic surgery is performed to repair facial skin lesions.

Objective: Electroconvulsive therapy (ECT) has been occasionally applied as a treatment for super-refractory status epilepticus (SRSE). However, the effects of ECT on electrographic activity and related clinical outcomes are largely unknown. Here, we use quantitative approaches on electroencephalography (EEG) data to evaluate the neurophysiological influences of ECT and how they may relate to patient survival.

Scleroderma is a rare connective tissue disease categorized as systemic or localized. Linear subtype of localized scleroderma usually manifests as a cutaneous linear scar-like lesion most commonly on the scalp. It may present with neurologic, ophthalmologic, and rheumatologic symptoms.

Introduction: Despite using beta oscillations within the subthalamic nucleus as a biomarker of akinesia or rigidity in Parkinson's disease, a specific biomarker for freezing of gait (FOG) remains unclear. Recently, scalp phase-amplitude coupling (PAC) measured through scalp electroencephalography (EEG) has emerged as a promising tool for analyzing brain function. In this study, we examined whether PAC could be a biomarker for FOG.
