242. "Kosovo, My Land"? : Slovenians, Albanians, and the Limits of Yugoslav Social CohesionJure Ramšak, 2021, original scientific article Abstract: The author examines the Kosovo crisis in the context of the pluralisation and democratisation of Slovenian society in the 1980s and early 1990s. This issue became a catalyst not only for the repositioning of structures of party leadership in relation to Belgrade, but also with respect to general public debates. By charting individual stages of the critical decade of 1981%1991, the author presents Slovenian perceptions of Kosovo%s political, economic, and social issues, first through the works of neo-Marxist critics and later through the activism of a group of left-liberal intellectuals, which included the provision of legal support and a high-profile social action related to the violations of Kosovar Albanian human rights. The author discusses the constraints encountered by this brief attempt to establish a pan-Yugoslav civil society initiative. At the same time, he shows how the complexities of the Kosovo crisis were used to coalesce the Slovenian nation into flight from Yugoslavia.

247. Stand up to excite the spine : neuromuscular, autonomic, and cardiometabolic responses during motor imagery in standing vs. sitting postureSidney Grosprêtre, Uroš Marušič, Philippe Gimenez, Gael Ennequin, Laurent Mourot, Laurie Isacco, 2021, original scientific article Abstract: Motor imagery (MI) for health and performance strategies has gained interest in recent decades. Nevertheless, there are still no studies that have comprehensively investigated the physiological responses during MI, and no one questions the influence of low-level contraction on these responses. Thus, the aim of the present study was to investigate the neuromuscular, autonomic nervous system (ANS), and cardiometabolic changes associated with an acute bout of MI practice in sitting and standing condition. Twelve young healthy males (26.3 % 4.4 years) participated in two experimental sessions (control vs. MI) consisting of two postural conditions (sitting vs. standing). ANS, hemodynamic and respiratory parameters, body sway parameters, and electromyography activity were continuously recorded, while neuromuscular parameters were recorded on the right triceps surae muscles before and after performing the postural conditions. While MI showed no effect on ANS, the standing posture increased the indices of sympathetic system activity and decreased those of the parasympathetic system (p < 0.05). Moreover, MI during standing induced greater spinal excitability compared to sitting posture (p < 0.05), which was accompanied with greater oxygen consumption, energy expenditure, ventilation, and lower cardiac output (p < 0.05). Asking individuals to perform MI of an isometric contraction while standing allows them to mentally focus on the motor command, not challenge balance, and produce specific cardiometabolic responses. Therefore, these results provide further evidence of posture and MI-related modulation of spinal excitability with additional autonomic and cardiometabolic responses in healthy young men.

249. Dual-task performance in hearing-impaired older adults : study protocol for a cross-sectional mobile brain/body imaging studyAnna Wunderlich, Oliver Vogel, Maja Maša Šömen, Manca Peskar, Madeleine Fricke, Klaus Gramann, Janna Protzak, Uroš Marušič, Bettina Wollesen, 2021, original scientific article Abstract: Background: Hearing impairments are associated with reduced walking performance under Dual-task (DT) conditions. Little is known about the neural representation of DT performance while walking in this target group compared to healthy controls or younger adults. Therefore, utilizing the Mobile Brain/Body Imaging approach (MoBI), we aim at gaining deeper insights into the brain dynamics underlying the interaction of cognitive and motor processes during different DT conditions (visual and auditory) controlling for age and the potential performance decrements of older adults with hearing impairments. Methods: The cross-sectional study integrates a multifactorial mixed-measure design. Between-subject factors grouping the sample will be age (younger vs. older adults) and hearing impairment (mild vs. not hearing impaired). The within-subject factors will be the task complexity (single- vs. DT) and cognitive task modality (visual vs. auditory). Stimuli of the cognitive task will vary according to the stimulus modality (visual vs. auditory), presentation side (left vs. right), and presentation-response compatibility (ipsilateral vs. contralateral). Analyses of DT costs and underlying neuronal correlates focus either on gait or cognitive performance. Based on an a priori sample size calculation 96 (48 healthy and 48 mildly hearing impaired) community-dwelling older adults (50%70 years) and 48 younger adults (20%30 years) will be recruited. Gait parameters of speed and rhythm will be captured. EEG activity will be recorded using 64 active electrodes. Discussion: The study evaluates cognitive-motor interference (CMI) in groups of young and older adults as well as older adults with hearing impairment. The underlying processes of the interaction between motor and cognitive tasks will be identified at a behavioral and neurophysiological level comparing an auditory or a visual secondary task. We assume that performance differences are linked to different cognitive-motor processes, i.e., stimulus input, resource allocation, and movement execution. Moreover, for the different DT conditions (auditory vs. visual) we assume performance decrements within the auditory condition, especially for older, hearing-impaired adults. Findings will provide evidence of general mechanisms of CMI (ST vs. DT walking) as well as task-specific effects in dual-task performance while over ground walking.
