Summary: Humans and other primates have a foveated visual system that reorients the fovea to objects of interest through saccadic eye movements. The control of saccadic eye movements is influenced by higher-level cognitive processes, impacting neural oculomotor circuits and cognitive mechanisms revealed through saccade parameters. This control system serves to quickly and accurately provide foveal vision of relevant targets in the visual field.

Summary: Previous studies have shown that the neural substrate for adaptation of saccadic eye movements involves the cerebellum and several cortical areas. This study aimed to understand the differences between forward and backward adaptation of saccades and their error processing and oculomotor changes. The results showed activation in specific cortical and subcortical areas related to adaptation and error signal processing, and revealed the involvement of the occipital cortex and MT/MST in the direction of adaptation. Overall, this study provides further evidence of the role of the cerebral cortex in saccadic adaptation and contributes to our understanding of oculomotor plasticity and its relationship with spatial cognition.

Summary: This study compared oculomotor performances in elderly depressed patients with and without suicidal behaviors, finding that patients with suicidal behaviors had fewer corrected AS errors and took longer to correct them. The research suggests that suicidal patients may have higher cognitive inflexibility, which could explain their difficulty in responding adequately to stressful environments and suicidal ideation.

Summary: Eye movements require a complex combination of rotation and translation of the eye. Eyeball translation significantly affects the coordination of eyeball rotation, particularly during blinks. Research has shown that saccadic eye movements during blinks result in significant overshoot of the target, but the eye returns to the target once the blink ends.

Summary: This study found a relationship between saccadic eye movement speed and the visibility of the phantom array effect. The faster the eye movement speed, the higher the visibility of the phantom array effect. Additionally, the phantom array effect was more visible at a wide viewing angle with faster eye movement speed. Furthermore, when individuals were grouped based on their eye movement speed, the mean speed of saccadic eye movement within each subgroup was related to the variations in the visibility of the phantom array effect.

Summary: This study investigated the metabolic brain correlates of ocular motor dysfunction in early Progressive Supranuclear Palsy (PSP) patients. The findings suggest the early involvement of Superior Colliculi (SC) in saccadic dysfunction, as decreased metabolism in SC correlates with decreased gain of vertical saccades, increased metabolism in SC and dorsal nuclei in the pons correlates with increased mean velocity of horizontal saccades, and decreased metabolism in posterior parietal region correlates with increased latency of horizontal saccades.

Summary: This study demonstrates that the central mesencephalic reticular formation is not only connected with horizontal gaze motoneurons, but also with vertical gaze motoneurons. There is a caudal to rostral gradient for horizontal to vertical saccades within the midbrain reticular formation. Additionally, a portion of the labeled terminals were found to be GABAergic, likely originating from downgaze premotor neurons.

Summary: Fatal crash rates have been trending downward since the mid-1990s, with greater declines for drivers ages 70 and older compared to middle-aged drivers (43% vs. 21%). While drivers ages 70-79 now have lower fatal crash rates per 100,000 licensed drivers and police-reported crash rates per mile traveled than drivers ages 35-54, their fatal crash rates per mile traveled and risk of dying in a crash remain higher due to driving fewer miles.

Summary: The study found that the saccadic reaction time was significantly prolonged in patients with mild, moderate, and advanced glaucoma, regardless of whether sensitivity loss was detected in SAP. This suggests that altered sensory processing in glaucoma may occur before changes in visual field sensitivity are detected, potentially enabling earlier diagnosis of the condition.

Summary: This study aimed to evaluate the long-term work incapacity post-road traffic injuries (RTIs) and examine the early factors influencing work capacity and factors that can be modified through intervention. The results showed that 20% of individuals experienced long-term work incapacity after the accidents. Factors such as gender, education level, income, occupation type, pre-existing comorbidities, and injury severity were negatively associated with return-to-work. Claiming injury compensation, early post-injury pain, and psychological distress were also key factors negatively affecting return-to-work.

Summary: This study aims to examine the risk of death among crash-involved teenage drivers. The results showed that teenage drivers carrying multiple teenage passengers were twice as likely to die compared to driving alone, and the risk increased seven times when carrying a combination of teenage and young adult passengers. The presence of adult passengers aged 35-64 years resulted in the lowest risk of death for teenage drivers.

Summary: The study found no association between menstrual cycle onset and lunar phase, but discovered that a higher proportion of good sleepers had their menstrual cycle beginning during the light period, while a higher proportion of poor sleepers had it begin during the dark period. Menstrual cycle onset during the dark period was associated with poorer subsequent subjective sleep quality, particularly with consecutive onsets during the dark period or at a rapidly changing lunar phase.

Summary: In this study, changes in wellbeing during COVID-19 social restrictions were investigated, and their relationship with outdoor daylight exposure and sleep-wake behavior was analyzed. The results showed that sleep quality, quality of life, physical activity, and productivity declined during social restrictions, while screen time increased and outdoor daylight exposure decreased. However, some participants reported no changes or even improvements. Larger reductions in outdoor daylight exposure were associated with poorer wellbeing and delayed mid-sleep times.

Summary: This study aimed to investigate the differences between the two core symptoms of night eating syndrome in the general Japanese population. The results showed that participants with evening hyperphagia and nocturnal ingestion had higher levels of anxiety and depression compared to those without NES. Evening hyperphagia was associated with higher BMI, shorter sleep duration, later sleep-wake schedule, and higher insomnia score, while nocturnal ingestion was associated with younger age, smoking habit, living alone, earlier sleep-wake schedule, and higher insomnia score. The characteristics of sleep duration and sleep-wake schedule in the two groups were opposite, suggesting differences in the sleep pathophysiology mechanisms.

Summary: In this study, electroencephalogram data was analyzed to compare the resting network activation between heavy media multitaskers (HMM) and light media multitaskers (LMM). The results showed that HMM had weaker activation in the attention network, but enhanced activation in the salience network. They also had an enhanced visual network and may feel less comfortable during resting-state periods. This suggests that chronic media multitasking leads to a bottom-up or stimulus-driven allocation of attention for HMM, while LMM use a top-down approach.
