Repeatability analysis of ICA-based harmonization for multi-site MRI data using dual projection models

NeuroImage
Integrating multi-site magnetic resonance imaging (MRI) datasets enhances statistical power and generalizability in neuroimaging research but introduces systematic variability, known as site effects, that can obscure true biological signals.

Optimization Of Ann-Training Geometric Algorithm In Independent Component Analysis (Ica)

, 2014
One of the most actual tasks of information processing today is the problem of separating a mixture of several sources of signals. Moreover, the solution requires the on-line processing mode. With this task successfully cope artificial neural networks (ANN). But for stable operation of the system, the ANN require training on specific algorithms.

Acupuncture alters cortical and corticomuscular functional connectivity in stroke patients with motor dysfunction

Journal of Intelligent Medicine, EarlyView.
Abstract Stroke is a leading cause of global mortality and disability, often resulting in severe motor dysfunction. Acupuncture has shown promise in stroke rehabilitation, but its neural mechanisms remain unclear. This study investigated the immediate effects of acupuncture at GV26, PC6, and SP6 on cortical and corticomuscular functional connectivity ...

Enhancing spatial cognition through origami training: Insights from brain connectomes

Journal of Intelligent Medicine, EarlyView.
Origami training enhances spatial cognition via measurable brain network changes (EEG/eye‐tracking). The mental rotation and folding tasks validate these gains. This low‐cost method offers a scalable intervention for cognitive decline. Abstract Spatial cognition is a key ability of human cognition and intelligence.

Relating Independent Components to Free-Vibration Modal Responses

Shock and Vibration, 2010
In recent literature, attempts have been made to apply Independent Component Analysis (ICA) techniques to the modal identification problem. Paramount to this task is establishing a relationship between the source components realized using the suggested ...

Barriers to nutrition following neurosurgery: A descriptive cohort study

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Neurological trauma results in a state of hypermetabolism. Existing literature has explored barriers to adequate nutrition following traumatic brain injury. Despite clinical similarities, it remains unclear whether similar nutritional barriers are faced following both planned and emergency neurosurgical procedures.

Impact of CYP2C19 Genotype Variants on PCSK9 Inhibitor Efficacy in Lipid‐Lowering Among Patients With Symptomatic Intracranial Atherosclerotic Stenosis

Lipids, EarlyView.
ABSTRACT Ischemic stroke is frequently associated with symptomatic intracranial atherosclerotic stenosis (sICAS), is a leading cause of global disability and mortality. Current guidelines recommend dual antiplatelet and intensive statin therapies. Proprotein convertase subtilisin 9/kexin type 9 (PCSK9) inhibitors have emerged as a potent lipid‐lowering

Aberrant Beta‐Band Network Alteration Preceding Freezing of Gait in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Freezing of gait (FOG) is a debilitating motor symptom observed in the advanced stages of Parkinson's disease (PD), characterized by an abrupt inability to initiate or continue forward walking. Whole‐brain functional connectivity analysis has shown promise in elucidating the underlying pathophysiology and identifying potential ...

Temporal Dynamics of Parkinson's Disease Tremor: Clinical and Neuroimaging Insights

Movement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is a progressive neurodegenerative disorder clinically defined by three cardinal motor symptoms: bradykinesia, rigidity, and tremor. Although the natural history of bradykinesia and rigidity is well described, the evolution of tremor as the disease progresses remains controversial. Objectives The goal was to
