Obstructive sleep apnea (OSA) patients exhibit neurological symptoms, driving research in medicine and clinical neurology. Neurologists radiologists explore detection methods to identify unique neural features associated with OSA the atypical nervous system. Neuroimaging encompasses studying structural, functional connectivity (FC), neurometabolic aspects of brain. Limited resources OSA's heterogeneity pose challenges effective neuroimaging research. This study aims conduct a bibliometric analysis key trends emerging themes. utilizes various techniques, including MRI, structural diffusion tensor imaging, magnetic resonance spectroscopy, electroencephalography, among others.

Stress is a crucial factor affecting social decision-making. However, its impacts on the behavioral and neural processes of females' unfairness decision-making remain unclear. Combining computational modeling functional near-infrared spectroscopy (fNIRS), this study attempted to illuminate neurocomputational signature in females. We also considered effect trait stress coping styles. Forty-four healthy young females (20.98 ± 2.89 years) were randomly assigned group (n = 21) control 23). Acute psychosocial was induced by Trier Social Test (TSST), participants then completed one-shot ultimatum game (UG) as responders. The results showed that acute reduced adaptability fairness lead more random responses. Moreover, group, high level negative style predicted deterministic decision. fNIRS led an increase oxy-hemoglobin (HbO) peak right temporoparietal junction (rTPJ), while decreased activation left middle temporal gyrus (lMTG) when presented moderately unfair (MU) offers. This signified involvement mentalization inhibition moral processing. individuals with higher scores decision behaviors under stress.
