Introduction: The vergence neural system was stimulated to dissect the afferent and efferent components of symmetrical vergence eye movement step responses. The hypothesis tested was whether the afferent regions of interest would differ from the efferent regions to serve as comparative data for future clinical patient population studies.
Methods: Thirty binocularly normal participants participated in an oculomotor symmetrical vergence step block task within a functional MRI experiment compared to a similar sensory task where the participants did not elicit vergence eye movements.
Article Synopsis
- The CONCUSS trial is a randomized clinical trial aimed at comparing the effectiveness of immediate office-based vergence/accommodative therapy with delayed therapy for treating concussion-related convergence insufficiency in young people aged 11-25.
- The study involves enrolling 100 participants and assessing outcomes after both immediate and delayed treatments, focusing on changes in convergence abilities and symptoms.
- Key elements of the study include clear definitions of conditions, standardized protocols, a delayed treatment group, and the use of advanced measures like eye movement recording and brain imaging to evaluate the treatments' effects.
Introduction: Convergence Insufficiency (CI) is the most prevalent oculomotor dysfunction of binocular vision that negatively impacts quality of life when performing visual near tasks. Decreased resting-state functional connectivity (RSFC) is reported in the CI participants compared to binocularly normal control participants. Studies report that therapeutic interventions such as office-based vergence and accommodative therapy (OBVAT) can improve CI participants' clinical signs, visual symptoms, and task-related functional activity.

- Existing models for pesticide bioconcentration in earthworms are limited in their applicability across various chemicals, soils, and species, hindering their use in risk assessment.
- We developed a first-order kinetic accumulation model using data from experiments on three earthworm species, five pesticides, and five types of soil, finding it effective in predicting body loads from both porewater and bulk soil concentrations.
- Our model outperformed existing ones and could be used alongside models that factor in earthworm movement and changes in soil pesticide levels due to degradation and transport.
Blackleg and soft rot diseases represent a major threat to the health of potato () and other vegetable, ornamental and fruit crops worldwide; their main causal agents are species of and . In May 2022, 60% of potato plants (cv. Spunta) in a production field in Córdoba, Argentina (31°32'36''S 64°09'46''W) showed soft rot, blackleg and wilt.
