This study aims to improve understanding of the anatomy of the deep brain nuclei relevant to deep brain stimulation as well as stereotactic lesioning procedures, including radio frequency, high-focused ultrasound, and radiosurgery. We created interactive, three-dimensional virtual models from cadaveric dissections and radiological segmentation. We used five brain specimens (ten hemispheres) obtained from routine autopsies, prepared according to Klingler's method.

Dr. Hulusi Behçet (1889-1948) was a renowned Turkish dermatologist who made significant contributions in the field. His innovative research led to the discovery of Behçet's disease, a complex autoimmune disorder characterised by recurring mouth ulcers, inflammation of the eye, genital ulcers, and skin lesions.

Background: Having social support improves one's health outcomes and self-esteem, and buffers the negative impact of stressors. Previous studies have explored the association between social support and brain activity, but evidence from task-dependent functional connectivity is still limited.
Aims: We aimed to explore how gradually decreasing levels of social support influence task-dependent functional connectivity across several major neural networks.

Deep brain stimulation (DBS) is a well-established treatment for motor circuit disorders such as Parkinson disease, dystonia, and essential tremor, particularly when pharmacological interventions are insufficient. The increase in DBS-related publications and the growing number of patients receiving DBS highlight the acceptance and refinement of the procedure. Despite its widespread use, comprehensive anatomical knowledge of deep brain nuclei remains critical for enhancing clinical efficacy.

Article Synopsis
- - This study explores how visual masking and attentional load affect information processing in perception, using a combination of metacontrast and attentional load in experiments.
- - Behavioral results showed that attentional load significantly influenced masking strength, indicating that it impacts how we perceive stimuli based on their timing.
- - Neural analyses revealed different effects of masking and attentional load on early and late components of brain activity, suggesting that these influences vary throughout different stages of visual processing.
