Building on Bruno Nardi's reinterpretation (1959), which suggests a medical explanation rather than mere ridicule, this study analyzes the sonnet through medieval physiological and medical theories. Dante da Maiano's diagnosis, influenced by Galenic and Aristotelian thought, links the poet's delirious dream to harmful vapors rising from the testicles to the brain. These vapors, produced by excessive heat and imbalance in the reproductive organs, were thought to cause mental disturbances by drying out the brain, a common medieval explanation for lovesickness. The article highlights the conceptual connection between the brain and the testicles, recognized in medieval medical theory, especially in the works of Galen and Albert the Great. By situating Dante da Maiano's response within this scientific framework, the article reinterprets his advice-like washing the testicles to mitigate harmful vapors-as a serious medical recommendation rather than as derision. This perspective enhances our understanding of the interplay between physical health and mental states in medieval thought, offering fresh insights into Dante's dream and its broader medical and philosophical implications.</p>","PeriodicalId":49997,"journal":{"name":"Journal of the History of the Neurosciences","volume":" ","pages":"517-525"},"PeriodicalIF":0.3,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143537955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rapid development of this field is often attributed to the emergence of powerful brain-imaging techniques and, around the millennium, the merging of the neuroscience of brain networks with modern mathematical graph theory. However, little is known about the historical roots of this concept. It is interesting to know when the first traces of a concept of brain networks can be found in the work of early neuroscientists, how this concept evolved over time, and what factors may have influenced this evolution. This study aims to set a first step in addressing these questions by a detailed analysis of David Ferrier's classic study, <i>The Functions of the Brain</i>. From this analysis it will become clear that, in addition to a clear notion of localized functions in the brain, Ferrier speculated in several places about the need for several of these brain regions to communicate and interact in order to bring about higher brain functions. He referred to this perspective on the brain as a \"complex whole,\" which could be interpreted as an early precursor of the modern concept of brain networks.</p>","PeriodicalId":49997,"journal":{"name":"Journal of the History of the Neurosciences","volume":" ","pages":"461-471"},"PeriodicalIF":0.3,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142331347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, several respects in which Beritashvili is claimed to be anti-Pavlovian are ways in which he resembles Pavlov. Turning my attention to Beritashvili's critics in the Soviet Union, those responsible for his censure, I argue that it is the critique of Beritashvili that runs counter to the norms Pavlov embraced. I contest the claim that his alleged deviations from Pavlovian orthodoxy justify classification as anti-Pavlovian in a sense that is either historically accurate or philosophically interesting, and submit that the grounds on which Beritashvili is derided as anti-Pavlovian would also justify labeling Pavlov himself as anti-Pavlovian.
