He is credited with founding the multidisciplinary Tartu-Moscow School of Semiotics. As a cultural theorist and humanist, he was highly influential across many fields, but his contributions to theories about the brain as a semiotic system have often been overlooked.</p> <p>Topics such as the asymmetry of the brain hemispheres, the “untranslatable” specialization of their respective “languages”, interhemispheric dialogue, and the unity of consciousness were frequent subjects of discussion within the scientific community that formed around the multidisciplinary Tartu-Moscow (and Leningrad) group. Recently, scholars such as E. Andrews and T.V. Chernigovskaya have highlighted the influence and relevance of the “neurosemiotic” model proposed by Yu.M. Lotman in the late 1970s. However, our impression is that a fundamental aspect, which Yu.M. Lotman considered indispensable for the functioning of any “thinking system”, has been overlooked in the application of this model to contemporary studies of neurophysiology. This aspect is the intersemiotic translation device that Yu.M. Lotman calls the “semiotic boundary”. We can consider this as a “third” structure of intersection between the two hemispheres, which actively operates to translate specialized information systems reciprocally. In this paper, we will attempt to restore its significance according to an interpretation updated to the most recent discoveries in cognitive neuroscience.</p></abstract><trans-abstract xml:lang="ru"><p>Юрий Михайлович Лотман (1922–1993) — советский семиотик, литературовед и культуролог. Ему приписывают основание междисциплинарной Тартуско-московской семиотической школы. Как теоретик культуры и гуманист, он оказал большое влияние на многие области человеческого знания, но его вклад в теории о головном мозге как семиотическом устройстве часто отходит на второй план.</p> <p>Такие темы, как асимметрия полушарий головного мозга, «непереводимая» специализация используемых ими «языков», межполушарный диалог и единство сознания, были частыми предметами обсуждения в научной среде, сформировавшейся вокруг междисциплинарной московско-тартуской (и ленинградской) группы. В работах последних лет ученые Э. Эндрюс и Т.В. Черниговская заострили внимание на актуальности нейросемиотической модели Ю.М. Лотмана, которая зародилась еще в конце 1970-х годов. Однако сложилось впечатление, что при применении этой модели в современных нейрофизиологических исследованиях был упущен из виду фундаментальный аспект, который Ю.М. Лотман считал неотъемлемым в функционировании любой «мыслящей системы». Этот аспект представляет собой средство интерсемиотического перевода, называемое Лотманом «семиотической границей». Его можно рассматривать как «третью» структуру пересечения двух полушарий, активно работающую над двусторонним переводом специализированных информационных систем. В настоящей статье мы попытаемся восстановить его значение, опираясь на интерпретацию, обновленную с учетом последних открытий в области когнитивной нейронауки.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Yuri Lotman</kwd><kwd>hemispheric asymmetry</kwd><kwd>multimodal semiotics</kwd><kwd>semiotic boundary</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Юрий Лотман</kwd><kwd>межполушарная асимметрия</kwd><kwd>мультимодальная семиотика</kwd><kwd>семиотическая граница</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Chernigovskaya TV.
