Summary: The current study aimed to investigate the effects of pain observation on motor activity, and found an increased motor cortical output during pain observation regardless of whether participants were in an active or passive state. This finding contradicts previous literature on empathy for pain, which often shows a decrease in motor cortical output during pain observation.

Summary: SCA6(84Q) mutant mice show impaired vestibulo-ocular reflex and optokinetic reflex, as well as significantly reduced VOR motor learning, suggesting altered cerebellar output contributes to gaze stabilization and motor learning deficits.

Summary: Amblyopia severely affects saccadic eye movements and distorts the spatiotemporal coordination between the visual and motor systems. Validated clinical tests related to saccadic eye movements are not currently performed in routine clinical eye examinations.

Summary: Humans integrate multiple sources of information for action-taking, allocating weight to each source based on its reliability, a crucial property of Bayesian inference. This study used a smooth pursuit eye movement task to investigate neural and behavioral evidence of Bayesian information integration. Results showed a preference for cue-based direction when the target motion was weak and unreliable, suggesting the presence of Bayesian information integration in human oculomotor behavior.

Summary: The study found that interpreters exhibit predictive eye movements in simultaneous interpreting tasks, both before and after training. However, it remains unclear whether training in simultaneous interpreting affects the timing and magnitude of these predictions.

Summary: This study investigated the differences in EEG activity patterns during the tracking of visible and occluded moving targets. The results showed that there were differences in EEG activity patterns in various brain regions during occluded sections and visible sections compared to a nonoccluded task.

Summary: This study demonstrates that neck muscle activity can provide insights into neural sequence planning signals during sequential saccade planning. The rapid connection between the frontal eye fields (FEFs) and neck muscles is maintained, allowing for parallel programming of multiple saccadic eye movements. These findings suggest the existence of coordinated eye-head responses to sequential gaze shifts.

Summary: This study proposes a novel pre-processing method for eye-gaze tracking using a camera to monitor the front of the face. The method simplifies gaze direction detection and has low estimation errors and short execution time.

Summary: Mild traumatic brain injury, also known as concussion, affects a significant portion of the global population, with common symptoms including eye movement dysfunction. Recent advancements in MRI have shed light on brain damage in these patients, but there are still knowledge gaps that need to be further explored.

Summary: This study investigates the control of gaze in primates, showing that the combination of eye and head movements in gaze-shifts depends on the initial eye position. The study proposes a neural mechanism in the superior colliculus and uses a spiking neural network model to explain this process.

Summary: Pupil size is constantly changing and mainly determined by global luminance signals. It also responds to cognitive and arousal processes, with larger dilation observed in higher levels of cognitive or arousal processing. However, there is a lack of established pupil analysis focusing on the frequency domain, particularly in the context of arousal and cognitive modulations.

Summary: The study investigated the impact of target pre-cues on quiet eye duration (QED). Results showed that shorter QED following the most precise target pre-cueing suggested that some pre-programming had occurred before quiet eye initiation.

Summary: The study found that goalkeepers were more likely to delay the start of movement in order to predict the direction of a penalty kick. Microsaccades and small saccades could improve athletes' perception during the critical movement initiation phase, shifting attention from covert to overt to identify essential cues for guiding action.

Summary: Sounds can impact the latency of visually guided saccades, but the modulation is weaker compared to perceptual temporal judgments. Auditory and gap/overlap effects modulate saccade latencies in a similar way but reflect independent mechanisms.

Summary: During action preparation, loud acoustic stimuli (LAS) can trigger movements at very short latencies in a phenomenon known as the StartReact effect. Contrary to the initial proposal of a separate subcortical mechanism, this study provides evidence that responses to LAS can be explained by a combination of stimulus intensity effects and preparatory states. The findings demonstrate the involvement of cortically mediated preparatory processes in shaping reactions to LAS.
