Article Abstract

Gaze control is required for applying visual stimuli to a particular area of the visual field. We developed a visual field test with gaze check tasks to investigate hemianopia. In this test, participants must report the presence or absence of visual stimuli when a small object at the fixation point vibrates. Trials in the absence of visual stimuli were used as gaze check tasks, since the vibration could be observed only when the gaze was directed at the fixation point. We evaluated the efficacy of our test in four control participants and one patient with homonymous hemianopia who was unaware of the defects in the left visual field. This patient presented hemianopia in the test with gaze check tasks, but not when the gaze check tasks were omitted. The patient showed spontaneous gaze movements from the fixation point to the upper left direction, as well as scanning of the left visual field during the test without gaze check tasks. Thus, we concluded that the visual defects in this patient were compensated in daily life by spontaneous eye movements coordinated with visual information processing. The present results show the usefulness of the visual field test with gaze check tasks.

Introduction: Interprofessional simulation (IP-Sim) training in crisis resource management (CRM) is widely used to improve team performance. Emerging social sensor-based technology and measurement provide an opportunity to enhance IP-Sim. Using these methods, signals generated by team members in action are collected, analyzed, and presented in a debriefing session as visual aids and statistics that summarize behavioral markers of teamwork and taskwork.

Introduction: There is a research gap on how racism impacts the mental health of midwives in Ontario. Our aim was to conceptualize the impact of racism on racialized midwives in Ontario.

Methods: Informed by constructivist grounded theory, we analyzed data contributed by racialized midwives in Ontario who participated in focus groups and interviews as part of a larger study about mental health.

Re-focusing visual working memory during expected and unexpected memory tests.

A classic distinction from the domain of external attention is that between anticipatory orienting and subsequent re-orienting of attention to unexpected events. Whether and how humans also re-orient attention 'in mind' following expected and unexpected working-memory tests remains elusive. We leveraged spatial modulations in neural activity and gaze to isolate re-orienting within the spatial layout of visual working memory following central memory tests of certain, expected, or unexpected mnemonic content.

Background: Involution or aging is the most common cause of lower eyelid entropion (in-turning of eyelid margin) in the elderly population. Various pathomechanisms have been postulated for its occurrence. Aging leads to laxity of tissues and loss of muscle tone.

Article Synopsis
  • Ganglioneuroma is a rare benign tumor that can originate from the sympathetic nerves, and this case describes the second instance of such a tumor arising from the fifth cranial nerve in a pediatric patient.
  • A 7-year-old boy presented with left-sided facial symptoms and seizures, and imaging revealed a significant lesion near the fifth nerve, which was confirmed to be a ganglioneuroma through histopathological analysis.
  • Surgical removal of the tumor was performed successfully using a specific approach, highlighting the importance of considering ganglioneuroma in similar clinical scenarios involving lesions in the brain's Meckel's cave area.
