AI Article Synopsis
- The study examined how the two hemispheres of the brain respond differently to word priming based on semantic relationships.
- Significant differences in reaction times and brain activity were found for associatively related word pairs, with some trends for categorically related words in the left visual field.
- Event-related potentials indicated distinct timing patterns of associative priming effects, highlighting that the right hemisphere shows a delayed response to semantic relationships compared to the left hemisphere.
Article Abstract
To investigate hemispheric differences in the timing of word priming, the modulation of event-related potentials by semantic word relationships was examined in each cerebral hemisphere. Primes and targets, either categorically (silk-wool) or associatively (needle-sewing) related, were presented to the left or right visual field in a go/no-go lexical decision task. The results revealed significant reaction-time and physiological differences in both visual fields only for associatively related word pairs, but an electrophysiological difference also tended to reach significance for categorically related words when presented in the left visual field. ERP waveforms showed a different time-course of associative priming effects according to the field of presentation. In the right visual field/left hemisphere, both N400 and Late Positive Component (LPC/P600) were modulated by semantic relatedness, while only a late effect was present in the left visual field/ right hemisphere.

Retinal Capillary Ischemia Following Migraine: A Case Report.

Migraine, a neurological disorder often accompanied by symptoms such as visual disturbances, nausea, and photophobia, involves complex interactions between genetic and environmental factors, while vascular factors are also implicated, influenced by both genetic predisposition and environmental triggers. This case report discusses a 41-year-old male with a history of migraine with visual aura, presenting with sudden left-eye visual loss. Comprehensive ophthalmologic examination revealed a central scotoma, while multimodal imaging, including spectral-domain optical coherence tomography (SD-OCT), showed focal alterations in the outer plexiform layer.

Purpose: Retrospective study to review scleral lens outcomes in the pediatric population over a 21-year period, at a single clinical center.
Results: A total of 209 pediatric eyes (108 males and 101 females), distributed between 97 right and 112 left eyes, of which 147 eyes had ocular surface disease and 62 eyes had irregular cornea/refractive conditions, were treated with scleral lenses over a 21-year period. The mean age at the time of treatment initiation was 10.

A patient with known pulmonary atresia and intact ventricular septum and ductal stent presented with low cardiac output and arrythmia. Intraoperatively, the patient was found to have an anomalous left coronary artery arising from the pulmonary artery. After reimplantation of the left coronary artery to the aortic root and placement of a central shunt, the patient progressed well and was discharged home.

Undetected coronary anomalies at Norwood procedure are associated with poor prognosis due to inadequate myocardial protection. We report a case of anomalous origin of the right coronary artery from the main pulmonary artery trunk with hypoplastic left heart syndrome and aortic atresia. Although, during bilateral pulmonary artery banding as initial palliation, the proximity between the right coronary artery origin and the aortic root made a visual diagnosis difficult, it was diagnosed using computed tomography before the Norwood procedure.
