NCT06587113
The goal of this study is to investigate the finding that there are large individual differences in how participants move their eyes during active visual search. For example, some individuals tend to fixate, that is point their eyes steadily at a single location, for longer than other individuals before moving to another location. This experiment will use behavioral tasks to measure an individual's attentional and inhibitory functioning, and then see how each of these contributes to between-participant variability in eye movement behavior during visual search.
NCT07199049
This prospective observational study will evaluate neuro-mimic indicators of anesthesia depth, including eyelid reflex, eyeball movements, and pupil responses, in patients undergoing elective surgery under general anesthesia. Sixty adult patients will be observed at three standardized time points: after induction, during skin incision, and mid-surgery. All parameters will be recorded alongside bispectral index (BIS) monitoring. The study aims to determine whether these observable signs correlate with anesthesia depth, contribute to early detection of intraoperative awareness, and provide a basis for developing non-invasive depth monitoring systems.
NCT07278141
The goal of this clinical trial is to determine the effect of a combined therapeutic intervention program with anaerobic exercises (resistance exercises) and dual tasks on the physical, oculomotor, and executive functions of older adults with mild cognitive impairment. The main questions it aims to answer are: • How effective will a therapeutic intervention program combining resistance exercises with dual tasks be in improving the physical, oculomotor, and executive functions of older adults with mild cognitive impairment living in the community? Researchers will compare the effectiveness of a resistance exercise training program combined with dual tasks versus a resistance-only exercise training program to see if it improves the physical, oculomotor, and executive functions of older adults with mild cognitive impairment Participants Will: * Receive resistance exercises, resistance exercises combined with dual tasks. or the standard health care. The intervention programs will consist of 3 weekly sessions over 8 weeks. * Before the start and after the completion of the programs, they will be evaluated using a battery of tests. This includes sociodemographic and general health background, physical fitness tests, as well as assessments of executive functions and oculomotor Saccadic movements and anti-saccadic error. * be required to sign a consent form.
NCT07105462
This randomized controlled trial is designed to investigate whether a novel visual training system can improve eye coordination, reaction time, and hitting accuracy in competitive badminton players. The training utilizes a device called the Automatic Dual Rotational Risley Prisms (ADRRPs), which presents alternating base-in and base-out prism demands to stimulate vergence eye movements. This type of training aims to enhance the eyes' ability to converge and diverge quickly and accurately-a function that is important for visual clarity and motor performance during fast-paced sports. A total of 26 collegiate badminton athletes aged 18 to 25 years will be recruited from two universities in Taiwan. Participants will be randomly assigned to one of two groups: a visual training group using the active ADRRPs system, and a control group using a sham version of the same device containing plano lenses (with no prism effect). Training will be delivered twice per week for four weeks, with each session lasting 15 minutes. During each session, participants will view a video while the device applies alternating prism stimulation based on each individual's pre-measured fusional vergence capacity. Outcome measures will be assessed at baseline and after the four-week training period. These include vergence facility (cycles per minute), accommodative facility (flipper test), near point of convergence, and positive fusional vergence at near. Reaction time will be measured using a light-based agility task with BlazePod sensors, and hitting performance will be evaluated using a shuttlecock launcher that delivers randomized targets to various court zones. All participants will be monitored for any adverse events, and any symptoms such as diplopia, dizziness, or discomfort will be documented. Data will be analyzed as described in the Statistical Analysis Plan.

Behavioral disorders in adolescents are defined by a set of diverse behaviors (such as aggressiveness, agitation, clastic crisis, running away and endangerment) whose common characteristic is the predominance of action/ mentalization. These disorders are associated with significant morbidity and high mortality linked to a high rate of suicide or attempted suicide. Behavioral disorders are also associated with an alteration of mentalizing capacities, that is the psychic process by which the adolescent imagines and interprets his behavior and that of others on the basis of mental states such as needs, desires, beliefs or feelings. The disorders are also associated with emotional dysregulation. To date, the psychopathological processes underlying behavioral disorders in adolescents are unknown and prevent from offering appropriate psychological care. Thus, it seems essential to characterize this clinical population by integrating both its intrapsychic representations and the physiological parameters of emotional regulation associated with it. This project is a first step towards a larger-scale research project aimed at evaluating treatment by TBM (therapies based on mentalization) in adolescents with behavioral disorders.

The objective of this study is to determine the effects of electrical brain stimulation (EBS) on visual search in natural scenes in humans.
