‘Balkan Hospitality Opens Doors: Studying Dialects on the Verge of Extinction
You cannot study spoken dialects from books. Instead, you need to go to a village, seek out its elders, and earn the trust of local residents before you can record hours of spontaneous stories. This is how Natalia Muravleva, Associate Professor at the Faculty of Humanities, conducts her research. Her internship in Serbia continued her long-standing study of dialects spoken by Macedonian settlers. In this interview, she discusses how diaspora cultural centres help researchers reach informants, why native speakers need to be interviewed only in their own language (otherwise, as she puts it, they may 'break'), and how a single field season helped her finalise her monograph. She also shares warm memories of autumn in Belgrade and of colleagues with whom grammar can be discussed in three languages at once.

Mathematical problem solving: behavioral and neuroimaging studies

P. 277–277.
K.V. Konopkina, I.S. Matiulko, M. Arsalidou

The current study has three components: (a) a functional magnetic resonance imaging (fMRI) meta-analyses of past literature on mathematical operations; (b) a behav- ioral study to validate a math protocol with parametric changes in the difficulty of math problems that use addition, subtraction, multiplication and division; and (c) an fMRI study that examines the brain correlates of mathematical operations (addition, subtraction, multiplication and division) in relation to subjective effort.

This project investigated for the first time the Right-Left-Right hypothesis using func- tional brain indices related to solving addition, subtraction, multiplication and divi- sion problems. The classic ideas of hemispheric dominance (i.e., visual-spatial abilities in the right hemisphere, verbal ones in the left hemisphere) cannot explain the study’s findings as the material provided were all numerical. We adopt a hypothesis derived from cognitive development to predict that hemispheric involvement stems from an interaction between an individual’s mental-attentional capacity and the mental demand of the task [Pascual-Leone, 1987; Arsalidou, Pascual-Leone, Johnson, 2010]. To test this hypothesis, we adopted a parametric design with several levels of difficulty (easy, within the individual’s competence level and above the individual’s competence level). Our results provide new insights on the brain correlates of mathematical problem solving as a function of operation and difficulty.

Neural correlates of vestibular adaptation in cosmonauts after long duration spaceflight
Schoenmaekers C., Jillings S., Mortaheb S. et al., NPJ MICROGRAVITY 2025 Vol. 11 Article 71
Long-duration spaceflight affects otolith-mediated ocular counter-roll (OCR) and brain function, but the relationship between these changes is unclear. This study examines whether OCR changes correlate with functional connectivity (FC) changes in the vestibular network in the same cosmonauts after a long-duration (6-month) spaceflight mission. Using a human vestibular atlas, we found that changes in FC ...

Effects of early neuroanatomical variants on reading skills and brain function in typical adult Italian readers
Del Maschio N., Bellini C., Giannachi M. et al., Brain Structure and Function 2025 Vol. 230 Article 55
Reading is a core feature of human communication that develops throughout intensive academic training. Recently, a group of studies examined whether neuroanatomical variants that predate literacy acquisition may influence reading abilities at later stages of life, yielding mixed results. To complement and expand previous knowledge, we used multimodal magnetic resonance imaging (MRI) to investigate whether ...

Functional language lateralization during sentence completion in the healthy brain is not associated with the quantitative estimate of familial sinistrality
Tatiana Bolgina, Malyutina S., Hancock R. et al., Laterality 2025 Vol. 30 No. 1 P. 4–23
Familial sinistrality (left-handedness) has been suggested as a proxy for functional language lateralization in the healthy adult brain. Previous studies show that individuals with familial sinistrality tend to have less lateralized language-related brain activation, while individuals without familial sinistrality show greater left-hemispheric lateralization for language. However, familial sinistrality trait has always been treated as a ...

Brain Functional Connectivity During First- and Third-Person Visual Imagery
Pechenkova E., Mary Rachinskaya, Vasilenko V. et al., Vision 2025 Vol. 9 No. 2 Article 30
The ability to adopt different perspectives, or vantage points, is fundamental to human cognition, affecting reasoning, memory, and imagery. While the first-person perspective allows individuals to experience a scene through their own eyes, the thirdperson perspective involves an external viewpoint, which is thought to demand greater cognitive effort and different neural processing. Despite the frequent ...

Aging-related changes in cognitive flexibility: fMRI meta‐analysis
Chuikova Z., Faber A., Filatov A. et al., Behavioral and Brain Functions 2025 Vol. 21 Article 40
Cognitive flexibility—the ability to adaptively shift between different mental processes—is essential for human functioning. This meta-analysis examines age-related changes in neural correlates of cognitive flexibility using two common assessments: the Wisconsin Card Sorting Test (rule-discovery) and Task-Switching Paradigm (rule-retrieval). We synthesized findings from 85 articles comprising 118 experiments with 2246 participants across young, middle-age, and ...

Beyond what was said: Neural computations underlying pragmatic reasoning in referential communication
Zhen S., Martinez-Saito M., Yu R., Neuroimage 2025 Vol. 306 Article 121022
The ability to infer a speaker's utterance within a particular context for the intended meaning is central to communication. Yet, little is known about the underlying neurocomputational mechanisms of pragmatic inference, let alone relevant differences among individuals. Here, using a reference game combined with model-based functional magnetic resonance imaging (fMRI), we showed that an individual-level ...

Целью данного исследования было изучение возможности использования задачи с хвостами животных (animal tail task) в фМРТ-исследованиях в качестве методики для изучения мозговых механизмов объектного воображения. Результаты показали, что знакомство с животными, тип стимула и длина хвоста животного значительно влияли на время реакции и точность ответа. Зависимость времени реакции от длины хвоста свидетельствует о том, что задачи провоцировали пространственное воображение. ...
