Preprocessing is a critical yet challenging step in electroencephalography (EEG) research due to its significant potential impact on results. We present a protocol for semi-automatic EEG preprocessing incorporating independent component analysis (ICA) and principal component analysis (PCA) with step-by-step quality checking to ensure removal of large-amplitude artifacts. We describe steps for interpolating bad channels, removal of major artifacts by ICA and PCA correction, and exporting processed data. This protocol produced consistent results from users with a broad range of experience.

Importance: Maternal inflammation during pregnancy has been associated with an increased risk of neurodevelopmental disorders (NDDs), such as attention-deficit/hyperactivity disorder (ADHD) and autism, and cognitive deficits in early childhood. However, little is known about the contributions of a wider range of inflammatory proteins to this risk.
Objective: To determine whether maternal inflammatory proteins during pregnancy are associated with the risk of NDDs and executive functions (EF) in middle childhood and to identify protein patterns associated with NDDs and EF.
Background: There is a significant gap in the provision of care for transgender or gender-nonconforming patients. This population experiences a multitude of disparate health outcomes. Studies have demonstrated a clear knowledge gap among ED clinicians regarding the care for transgender or gender-nonconforming patients.

Repetitive drug use results in enduring structural and functional changes in the brain. Addiction research has consistently revealed significant modifications in key brain networks related to reward, habit, salience, executive function, memory and self-regulation. Techniques like Voxel-based Morphometry have highlighted large-scale structural differences in grey matter across distinct groups.

Hybrid multicompartment artificial architectures, inherited from different compartmental systems, possess separate microenvironments that can perform different functions. Herein, a hybrid compartmentalized architecture via hybridizing ferritin nanocage (Fn) with non-aqueous droplets using aminated-modified amphiphilic gelatin (AGEL) is proposed, which enables the generation of compartmentalized emulsions with hybrid multicompartments. The resulting compartmentalized emulsions are termed "hybrasome".

Glioblastoma multiforme (GBM) is the most aggressive type of brain tumor, characterized by its heterogeneity in cellular components, including reactive astrocytes and microglia. Since neuroimmune responses like astrogliosis and microgliosis gain recognition as vital factors in brain tumor progression, there is a growing need for clinically relevant models that assess the interactions between astrocytes, microglia, and GBM. Here, a NEuroimmune-Oncology Microphysiological Analysis Platform (NEO-MAP) is presented as a "new map" to observe astrocytic scar formation and microgliosis in response to GBM.
