Historically, the structure and presumed functions of the cerebral ventricles were often associated with the soul, intellect, memory, or mind. A comprehensive understanding of their true anatomy and functions emerged only through the application of scientific methods, including dissection, experimental research, and the correlation of structure with function. Many eponyms are reused to describe the anatomy of the cerebral ventricles. The aim of this study is to examine the historical development of the conceptualization of the ventricles and their interconnections, to elucidate their functions, and to investigate the origins of the eponyms commonly used in their anatomical description. The study was conducted as a scoping review in accordance with the PRISMA-ScR guidelines. PubMed, Web of Science, Scopus, and Google Scholar were searched. Data extraction and quality assessment were performed according to pre-established guidelines. The anatomical description of the cerebral ventricles can be traced back to Herophilus, Erasistratus, and Hippocrates and was further advanced by Galen (129-200). In the modern era, anatomical insight into the ventricles was refined through experimental research. Pioneering scholars such as Leonardo da Vinci (1452-1519), Andreas Vesalius (1514-1564), Franciscus de la Boe Sylvius (1614-1672), Alexander Monro (1733-1817), Domenico Cotugno (1736-1822), François Magendie (1783-1855), and Hubert von Luschka (1820-1875) made significant contributions to the field.

Its clinical phases may reflect dynamic reorganization of interacting neural circuits involved in sensory processing, homeostasis, pain modulation, and cognition. This review aims to synthesize current evidence and propose a stage-specific neural circuit dynamic model of migraine, linking each clinical phase to distinct patterns of circuit dysfunction and recovery. A narrative review of studies published between January 2010 and December 2024 was conducted using PubMed, Web of Science, and Embase. Controlled vocabulary and free-text terms were combined, and the article selection process was documented numerically to improve transparency. Evidence from human neuroimaging, electrophysiology, preclinical circuit manipulation, and neuromodulation studies was qualitatively integrated according to migraine phase and circuit domain. The interictal phase is characterized by vulnerable homeostasis, with heightened cortical excitability, impaired sensory gating, and weakened descending inhibition. During the prodromal phase, hypothalamic involvement and altered limbic-reward signaling may contribute to attack-related network priming. The ictal phase involves trigeminovascular activation, thalamocortical amplification, and engagement of pain and sensory networks; in migraine with aura, cortical spreading depression may contribute to these processes. Attack resolution may involve endogenous reset mechanisms engaging brainstem and hypothalamic modulatory systems, whereas chronic migraine may reflect maladaptive circuit plasticity and more persistent network reconfiguration. A stage-specific circuit framework can integrate fragmented evidence on migraine pathophysiology and may support circuit-based biotyping, biomarker development, and targeted neuromodulatory or pharmacological interventions.</p>","PeriodicalId":19429,"journal":{"name":"Neurology India","volume":" ","pages":"775-784"},"PeriodicalIF":0.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148897662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
