Background: The human white matter pathway network is complex and of critical importance for functionality. Thus, learning and understanding white matter tract anatomy is important for the training of neuroscientists and neurosurgeons. The study aims to test and evaluate a new method for fiber dissection using augmented reality (AR) in a group which is experienced in cadaver white matter dissection courses and in vivo tractography.
Methods: Fifteen neurosurgeons, neurolinguists, and neuroscientists participated in this questionnaire-based study. We presented five cases of patients with left-sided perisylvian gliomas who underwent awake craniotomy. Diffusion tensor imaging fiber tracking (DTI FT) was performed and the language-related networks were visualized separated in different tracts by color. Participants were able to virtually dissect the prepared DTI FTs using a spatial computer and AR goggles. The application was evaluated through a questionnaire with answers from 0 (minimum) to 10 (maximum).
Results: Participants rated the overall experience of AR fiber dissection with a median of 8 points (mean ± standard deviation 8.5 ± 1.4). Usefulness for fiber dissection courses and education in general was rated with 8 (8.3 ± 1.4) and 8 (8.1 ± 1.5) points, respectively. Educational value was expected to be high for several target audiences (student: median 9, 8.6 ± 1.4; resident: 9, 8.5 ± 1.8; surgeon: 9, 8.2 ± 2.4; scientist: 8.5, 8.0 ± 2.4). Even clinical application of AR fiber dissection was expected to be of value with a median of 7 points (7.0 ± 2.5).
Conclusion: The present evaluation of this first application of AR for fiber dissection shows a throughout positive evaluation for educational purposes.

Цифровые технологии XXI века способствуют формированию новых методологических подходов в гуманитарных науках, включая литературоведение и биографические исследования. Для автоматизации процессов сбора и аннотирования информации все чаще используют большие языковые модели (Large Language Models, LLM), включая ChatGPT. Развитие подобных инструментов стимулирует переход от традиционных методологических подходов, основанных на исключительно ручном аннотировании и экспертной верификации, к гибридным, ...

This study explores a fragment of the accentual system of the Pskov dialect, with data obtained from both a corpus and fieldwork. The focus is on a-stem nouns (1st declension), with the accent types and stress patterns described. The accent types of nouns are presented in tables, while the stress patterns are given in a dictionary format, allowing for a combined approach to describing the dialect’s accentual system. Special attention is paid to stress placement in the accusativus singularis form of a number of words, which in this case ...

В нганасанском языке существует сложная система чередования гласных в суффиксах, которая восходит к противопоставлению переднего и заднего рядов, но в результате многих передвижений гласных лишилась фонетической мотивации. Из всех суффиксов есть один глагольный, который, присоединяясь к корням, выражающим визуально наблюдаемые свойства, способен принимать гласные обоих сингармонических классов, соответственно меняя гласные и всех аффиксов, следующих за ...
