Summary: The study aimed to optimize the surgical procedure for parathyroid identification during thyroidectomy by using near-infrared autofluorescence (NIRAF). The experimental group using NIRAF had a higher number of identified parathyroid glands, lower inadvertent removal rate, and faster recovery of parathyroid function compared to the control group. The step-by-step NIRAF parathyroid identification method is effective in locating the parathyroid gland and protecting its function.

Summary: This study used fNIRS and gait parameters to evaluate cortical hemodynamics in patients with early-stage MS and healthy controls. The results showed enhanced cortical activation in the motor planning areas and differences in gait variability in the patient population. The association of cortical and gait parameters may reveal possible compensatory mechanisms related to gait during the early stages of the disease.

Summary: This study investigated the prefrontal cortex hemodynamics in people with multiple sclerosis (pwMS) and healthy controls during forward and backward walking, with and without a cognitive task. The results showed that the relative concentration of oxygenated hemoglobin (HbO) in the prefrontal cortex was higher during dual-task forward walking compared to single-task forward walking for both groups. Additionally, during single-task backward walking, the HbO concentration was higher in pwMS (DLPFC, FEF) and healthy controls (FEF, FPC) compared to forward walking. However, further research is needed to elucidate the differences between pwMS and healthy adults.

Summary: This study assessed the burn extent and depth in patients with burns using a custom-built 36-channel functional near-infrared spectroscopy system. Hemodynamic tissue signals measured during fNIRS showed significant differences between different burn categories, indicating that functional near-infrared spectroscopy can help with the early judgment of burn extent and depth by reflecting differences in the oxygen saturation levels in the skin.

Summary: This study utilized a new statistical analysis to investigate the relationship between fNIRS activation and performance in working memory tasks. The results revealed higher fronto-parietal activation in the 2-back task compared to the 1-back task, with inconsistent results in the 3-back task. Multivariate analysis showed differences in the relationship between brain activity and performance across different task difficulty levels.

Summary: In this study, a joint EEG and DOT neuronal source reconstruction algorithm was proposed, utilizing DOT reconstruction as the spatial prior of EEG reconstruction. Simulations showed that the algorithm can achieve higher spatiotemporal resolution than using either modality individually. Optimizing the placement of EEG electrodes and DOT optodes can further enhance the performance of the algorithm.

Summary: The study found that children with congenital unilateral upper-limb reduction deficiencies (ULD) showed significant activation in the ipsilateral motor cortex on the non-preferred side when using a prosthesis, unlike typically developing children. This ipsilateral response may be a compensation strategy used by the affected side to operate the prosthesis. This study is the first to report altered lateralization in children with ULD while using a prosthesis.

Summary: The study demonstrates how an integrative cognitive neuroscience approach, utilizing multilevel Bayesian statistics, can predict patterns of brain activity, explain behavioral data, and explore the impact of neural activity on errors in change detection in a study of visual working memory. The model-based analysis challenges traditional cognitive theories by suggesting that key areas in the dorsal attention network play a central role in change detection rather than working memory maintenance, contrary to previous interpretations of fMRI studies.

Summary: Offset analgesia is a phenomenon where a small decrease in noxious input leads to a dramatic drop in perceived pain intensity. This study used fNIRS to identify cortical correlates of offset analgesia and found opposing activation patterns in the cortical areas during the process. The right dorsolateral prefrontal cortex was found to be involved in evaluating pain intensity change.

Summary: This study aimed to investigate the transient effects of cognitive perturbations on postural control. It was found that more difficult cognitive tasks and the onset of the cognitive-motor challenge exhibited magnified effects on postural sway. Even the cessation of a cognitive task could have lingering perturbing effects on balance control.

Summary: This study found that greater depressive severity at 12-months postpartum was associated with lower connectivity between the right temporoparietal junction and the lateral prefrontal cortex, but greater connectivity between the right temporoparietal junction and anterior medial prefrontal cortex during mother-infant interaction. These findings suggest that in the context of depression, postpartum mothers' mentalizing about their infants' thoughts and feelings may be related to lower ability to express and regulate their own emotions, but greater ability to engage in emotional bonding with their infants.
