Summary: This study investigated the effect of mental workload on the causal influence brain regions exert over each other during multitasking. The results showed that with increased workload, causal connections shifted from the left to both sides of the brain, and the connectivity strengths could predict subtask performances. By studying the brain dynamics of mental workload, a predictor that supplements subjective self-report measures can be developed.

Summary: This study aims to establish a training system for the objective assessment of surgeons' skills. The results showed that the system could distinguish the tissue handling ability of operators based on force-related parameters. In addition, the experts agreed that the system had excellent content validity.

Summary: This study investigates the impact of multitasking requirements on cognitive load in robotic-assisted surgery. By collecting multimodal physiological signals and employing neural network models, the researchers found that EEG spectral analysis and eye-tracking measurements successfully distinguished cognitive workload levels under different surgical conditions. While HRV only showed significant differences in multitasking requirement conditions. The multimodal-based neural network models achieved an accuracy of up to 79% for both surgical conditions.

Summary: The safe application of transcranial direct current stimulation (tDCS) has been found to enhance surgical skill acquisition. By optimizing tDCS to target surgical task-related brain activation at different stages of motor learning, a causal link to learning behavior may be established. Further studies suggest that higher complexity laparoscopic tasks may lead to more robust activation of motor complexity-related brain areas compared to lower complexity tasks.

Summary: The aim of this study was to evaluate the use of portable neuroimaging measures in mapping the neural processes associated with learning basic surgical skills. The results showed that as trainees gained proficiency in laparoscopic surgery suturing task, there was increased activation in the prefrontal and sensorimotor areas of the brain. These findings contribute to the development of objective metrics for skill evaluation.

Summary: The study retrospectively reviewed 131 patients who underwent multivisceral resection, showing that the laparoscopic surgery group had higher BMI and less blood loss compared to the open surgery group. ESSQS-qualified surgeons had superior outcomes in laparoscopic surgery.

Summary: The human brain is difficult to access directly, so neuroimaging techniques like functional near-infrared spectroscopy (fNIRS) are commonly used for in vivo studies. fNIRS is a non-invasive and cost-effective method that can be applied to various study populations. Research using fNIRS in patients with diabetes and obesity has yielded conflicting results, with some studies finding increased hemodynamic response and others finding reduced response compared to controls. Additionally, individuals with obesity or binge eating disorder show reduced prefrontal activation, which can be restored with cognitive treatments. Further applications of fNIRS in metabolic disorders are also discussed.

Summary: Peer ratings for surgical skill varied for laparoscopic sleeve gastrectomy but did not have a significant impact on overall complication rates. Top rated surgeons had lower rates of specific surgical complications, including postoperative obstruction, hemorrhage, and reoperation; however, severe morbidity remained extremely low among all surgeons. Surgeons with higher skill ratings also showed faster operating times and higher annual case volumes for both sleeve gastrectomy and any bariatric procedure.

Summary: This study introduces an experiment on minimally invasive surgery training to autonomously assess non-technical skills and analyze workload using sensory data and a self-rating questionnaire. The results show that autonomous time series classification can effectively classify non-technical skills and workload components.

Summary: Malignant brain tumors are a group of tumors with high invasiveness and destructiveness, and near-infrared optical imaging techniques show potential in the diagnosis and treatment of brain tumors due to their noninvasiveness, high resolution, and large penetration depth.

Summary: A simulator has been designed to safely practice and assess axillary lymph node dissection (ALND), and its face, content, and construct validity has been investigated. The study found that the simulator demonstrated construct validity for ALND assessment and could be a useful tool for skills training and assessments.
