    The Reflection of Self-Esteem on the Brain Structure: a Voxel Based Morphometry Study in Healthy Young Adults
    (Turkish Neuropsychiatry Assoc-Turk Noropsikiyatri Dernegi, 2023) Erata, Mehmet C.; Eroğlu, Seda; Özkul, Burcu; Uslu, Özgül; Erdoğan, Yiğit; Kitiş, Ömer; Gönül, Ali Saffet
    Introduction: Low self-esteem is a known risk factor for mental illnesses. Neuroimaging studies have identified evidence for a functional association between default mode network (DMN) and self-esteem levels. However, it is not clear whether there is a similar association between trait self-esteem and the structures composing DMN. This study aimed to investigate the relationship between the DMN associated brain structures and trait self-esteem. Methods: We obtained 3T structural magnetic resonance imaging (MRI) data of 75 healthy subjects and detected anatomical regions correlated with their Rosenberg Self-Esteem scores via voxel-based morphometry (VBM). Results: We found positive associations between self-esteem and regional grey matter volumes in the right temporoparietal junction/ inferior parietal lobule (BA 39), cortical midline regions at precuneus/ dorsal cingulate cortex (BA 31), rostral and dorsal anterior cingulate cortices (BA 32). Conclusion: The results of the current study support the fMRI studies suggesting self-esteem levels associated with DMN. Further neuroimaging studies should consider the functional and structural coupling of the default mode network during the execution of the functions related to self-esteem.

    The Predictive Role of Nursing Students' Individual Characteristics and Psychological Resilience in Psychological Distress
    (Wiley, 2021) Serce, Ozgu; Ince, Sevecen Celik; Ozkul, Burcu; Gunusen, Neslihan Partlak
    Purpose This study aims to determine the predictive role of nursing students' individual characteristics and psychological resilience in psychological distress. Design and Methods This study is a descriptive cross-sectional study. The study sample included 652 nursing students. Binary logistic regression analysis was used for analysis. Findings It has been determined that 65.3% of nursing students have psychological distress. Having a chronic disease, being a woman, poor academic success, choosing the profession so as not to be unemployed, being single and low psychological resilience are factors that affect psychological distress. Practice Implications It is recommended to screen nursing students for psychological distress to increase interventions that improve the psychological resilience of risky students.

    Task-Dependent Functional Connectivity Changes in Response To Varying Levels of Social Support
    (Cambridge Univ Press, 2024) Burhanoglu, Birce Begüm; Uslu, Özgül; Özkul, Burcu; Oğuz, Kaya; Eroğlu-Koç, Seda; Kizilates-Evin, Gozde; Candemir, Cemre
    Background Having social support improves one's health outcomes and self-esteem, and buffers the negative impact of stressors. Previous studies have explored the association between social support and brain activity, but evidence from task-dependent functional connectivity is still limited.Aims We aimed to explore how gradually decreasing levels of social support influence task-dependent functional connectivity across several major neural networks.Method We designed a social support task and recruited 72 young adults from real-life social groups. Of the four members in each group, one healthy participant (18 participants in total) completed the functional magnetic resonance imaging (fMRI) scan. The fMRI task included three phases with varying levels of social support: high-support phase, fair phase and low-support phase. Functional connectivity changes according to three phases were examined by generalised psychophysiological interaction analysis.Results The results of the analysis demonstrated that participants losing expected support showed increased connectivity among salience network, default mood network and frontoparietal network nodes during the fair phase compared with the high-support phase. During the low-support phase, participants showed increased connectivity among only salience network nodes compared with the high-support phase.Conclusions The results indicate that the loss of support was perceived as a threat signal and induced widespread increased functional connectivity within brain networks. The observation of significant functional connectivity changes between fair and high-support phases suggests that even a small loss of social support from close ones leads to major changes in brain function.

    Gradual Loss of Social Group Support During Competition Activates Anterior Tpj and Insula but Deactivates Default Mode Network
    (MDPI, 2023) Özkul, Burcu; Candemir, Cemre; Oğuz, Kaya; Eroğlu-Koç, Seda; Kizilates-Evin, Gozde; Ugurlu, Onur; Erdoğan, Yiğit
    Group forming behaviors are common in many species to overcome environmental challenges. In humans, bonding, trust, group norms, and a shared past increase consolidation of social groups. Being a part of a social group increases resilience to mental stress; conversely, its loss increases vulnerability to depression. However, our knowledge on how social group support affects brain functions is limited. This study observed that default mode network (DMN) activity reduced with the loss of social group support from real-life friends in a challenging social competition. The loss of support induced anterior temporoparietal activity followed by anterior insula and the dorsal attentional network activity. Being a part of a social group and having support provides an environment for high cognitive functioning of the DMN, while the loss of group support acts as a threat signal and activates the anterior temporoparietal junction (TPJ) and insula regions of salience and attentional networks for individual survival.
