The most complex in visual prosthesis is creation of the specific part of the interface that directly contacts with the tissues. In the paper discussed are questions of biocompatibility of microelectrode arrays and behavioral effects on animals (cats) for evaluating functionality of the bioprosthetic device and its ability to induce phosphenes (visual sensations without light). Presented are new experimental methods and obtained results that allowed to determine phospheneinducing parameters of brain cortex electric stimulation in cats. Special attention is focused on description of the microelectrode array properties necessary for safe application in humans during the long time span, which is essential in cortical visual prosthesis.</p>  <p> </p> <p> </p></abstract><trans-abstract xml:lang="ru"><p>Существует два основных подхода к протезированию зрительных функций у слепых людей с помощью «мозг-компьютерных» интерфейсов – на основе ретинальной либо кортикальной стимуляции посредством имплантируемых электродов. Наиболее сложным в зрительном протезировании является создание той части интерфейса, которая непосредственно контактирует с тканями организма. В статье рассматриваются вопросы биосовместимости микроэлектродных матриц и поведенческие эксперименты на животных (кошках) для оценки функциональности биопротеза и его способности вызывать фосфены – зрительные ощущения без светового воздействия. Приведены новая методика экспериментов и полученные результаты, позволившие установить параметры электрического раздражения коры головного мозга кошки, при которых возникают фосфены. Особое внимание уделено описанию свойств микроэлектродных матриц, необходимых для безопасного применения у человека в течение длительного времени, что подразумевается при создании кортикального зрительного протеза.</p></trans-abstract><kwd-group xml:lang="en"><kwd>visual cortical prosthesis</kwd><kwd>phosphenes</kwd><kwd>artificial visual system</kwd><kwd>biocompatibility</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>зрительный кортикальный протез</kwd><kwd>фосфены</kwd><kwd>искусственная система зрения</kwd><kwd>биосовместимость</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Базиян Б.Х., Гордеев С.А., Иванова М.Е., Ортманн В.В.
