Neurosciences

Neurosciences encompass a broad spectrum of research that seeks to unravel the structure, function and dynamic interactions within the nervous system. From the cellular mechanisms underlying synaptic transmission to the large‐scale organisation of neural networks that drive cognition, emotion and behaviour, this multidisciplinary field integrates experimental, computational and clinical approaches. Recent advances in neuroimaging, electrophysiology and computational modelling have deepened our understanding of brain dynamics, while innovative methods in brain–machine interfacing and neuromodulation are beginning to translate these insights into practical applications for diagnosing and treating neurological disorders.

Research in Nature Index

Several studies over the past two years have broadened our perspective on neurodegenerative diseases. Recent work underscores how dysfunctional myelin can precipitate amyloid-β deposition, shedding light on early mechanisms in Alzheimer’s disease pathogenesis [1]. Research into Parkinson’s disease has advanced our understanding of its molecular and clinical diversity, exemplified by large-scale cohort analyses using α-synuclein seed amplification assays to distinguish subtypes of sporadic and genetic Parkinson’s [2]. Meanwhile, new imaging tools, including a positron emission tomography tracer selective for α-synuclein aggregates, are transforming the early detection of synucleinopathies [3]. These advances build on earlier seminal findings pointing to a dynamic interplay between peripheral factors and the brain, such as how altered gut microbiota can modulate motor deficits and neuroinflammation in Parkinsonian models [4]. Together, these lines of research highlight the complexity of neurodegeneration, the synergy of environmental and genetic risk factors, and the promise of translational imaging and biomarker breakthroughs.
