Nerve injuries can be tantamount to severe impairment, standard treatment such as the use of autograft or surgery comes with complications and confers a shortened relief. The mechanism relevant to the regeneration of the optic nerve seems yet to be fully uncovered. The prevailing rate of vision loss as a result of direct or indirect insult on the optic nerve is alarming.

Background: The rarity of optic nerve sheath meningiomas (ONSMs) complicates the guidelines surrounding optimal treatment strategies and prognostic factors. There are limited data on the visual outcomes of those treated with radiotherapy versus those observed without treatment. This study aimed to characterize the clinical and radiographic presentations of patients diagnosed with ONSMs and to identify factors predicting improvement in visual function after treatment.

Depth completion is widely employed in Simultaneous Localization and Mapping (SLAM) and Structure from Motion (SfM), which are of great significance to the development of autonomous driving. Recently, the methods based on the fusion of vision transformer (ViT) and convolution have brought the accuracy to a new level. However, there are still two shortcomings that need to be solved.

Miller Fisher syndrome (MFS) is a rare Guillain-Barré syndrome (GBS) variant. The global incidence of GBS is approximately one to two in 100,000 children (aged 0 to 15 years) per year. Miller Fisher syndrome represents a further small subset, with the incidence being one to two in 1,000,000 children.

BOLD response can be fitted using the population receptive field (PRF) model to reveal how visual input is represented on the cortex (Dumoulin and Wandell, 2008). Fitting the PRF model costs considerable time, often requiring days to analyze BOLD signals for a small cohort of subjects. We introduce the qPRF ("quick PRF"), a system for accelerated PRF modeling that reduced the computation time by a factor ¿1,000 without losing goodness-of-fit when compared to another widely available PRF modeling package (Kay et al.
