Background: The available referential measures defining the zygomatic bone morphology are adequate enough for full determination of the zygoma positioning, especially for trauma surgery, but osteometric analysis of the zygoma positioning based on tomographic examinations could be useful in peroperative and postoperative imaging. In this study, we propose referential measures, taking into account the morphology and the symmetry of the zygoma. In addition, the reliability and reproducibility are considered.
Methods: Thirty normal computed tomography (CT) scans were used to establish the referential measures. The study involved preoperative imaging (27 CT and 1 cone beam CT [CBCT] scan), and postoperative imaging (6 CT and 22 CBCT scans) pertaining to 28 patients, showing a unilateral zygomatic fracture. In a precisely chosen axial cut in the orbito-meatal plane, 3 referential data were defined: namely, S, denoting the distance of the zygoma summit; αS, representing the angle between the summit and the symmetry axis passing through the clivus; and αZ, corresponding to the morphologic angle.
Results: The 3 referential measures S, αS, and αZ are reliable and reproducible by CT and CBCT examination. Those parameters can be used to evaluate the zygomatic symmetry. The postoperative asymmetries arise from an erroneous recovery of S, which was statistically significant at p = 0.0216.
Conclusion: On a single optimized axial cut, the new referential measures are useful and effective in preoperative and postoperative assessment of the residual bone asymmetries.

The default mode network (DMN) is intricately linked with processes such as self-referential thinking, episodic memory recall, goal-directed cognition, self-projection, and theory of mind. Over recent years, there has been a surge in examining its functional connectivity, particularly its relationship with frontoparietal networks (FPN) involved in top-down attention, executive function, and cognitive control. The fluidity in switching between these internal and external modes of processing-highlighted by anti-correlated functional connectivity-has been proposed as an indicator of cognitive health.

Background and aim Subthreshold depression is a potential risk factor for major depressive disorder. Although the neurobiological mechanism underlying major depressive disorder is well-established, the mechanism underlying subthreshold depression has not yet been fully elucidated. We investigated the characteristics of brain abnormalities in participants with subthreshold depression using near-infrared spectroscopy (NIRS) owing to its portability.

This study investigates if this is also the case for lower-proficiency bilinguals from a bilingual community, who use language more implicitly, and if there is more alignment with lower than with higher proficiency, provided the words to be aligned to are all highly familiar. In two experiments, Spanish-English bilinguals took turns with a confederate to name and match pictures in Spanish.

The aim of the current study was to investigate visual scan patterns for the self-face in infants with the ability to recognize themselves with a photograph. 24-month-old infants (N = 32) were presented with faces including the self-face in the upright or inverted orientation. We also measured infants' ability to recognize oneself in a mirror and with a photograph.
