neurology

Definition

Neurology is the medical specialty and scientific discipline focused on the structure, function, and disorders of the nervous system, encompassing the brain, spinal cord, peripheral nerves, and neuromuscular junctions. It investigates the molecular, cellular, and systems-level mechanisms underlying neurological diseases such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, epilepsy, and stroke. Neurological research integrates genetics, proteomics, neuroimaging, and electrophysiology to understand disease pathogenesis, identify biomarkers, and develop therapeutic interventions. The field is increasingly driven by systems biology approaches that map complex interactions between genes, proteins, metabolites, and environmental factors contributing to neurological dysfunction.

Visualize neurology in Nodes Bio

Researchers can use Nodes Bio to visualize complex neurological disease networks, mapping relationships between genetic variants, protein interactions, signaling pathways, and phenotypic outcomes. Network analysis reveals disease modules, identifies hub proteins as potential drug targets, and uncovers shared molecular mechanisms across different neurological conditions. Causal inference tools help distinguish driver mutations from passenger events in neurodegenerative cascades.

Example Use Case

A research team investigating Parkinson's disease uses network analysis to integrate GWAS data, protein-protein interactions, and gene expression profiles from patient brain tissue. They construct a disease network centered on LRRK2, SNCA, and PARK7 genes, revealing unexpected connections to mitochondrial dysfunction and autophagy pathways. The visualization identifies PINK1 as a convergent node linking multiple disease mechanisms, suggesting it as a promising therapeutic target. This systems-level view guides their experimental validation studies and drug screening efforts.
