Background: In children, pseudopapilledema is frequently caused by peripapillary hyperreflective ovoid mass-like structures (PHOMS) or optic disc drusen (ODD). While enhanced depth imaging (EDI) OCT can identify both, lack of cooperation, especially from younger children due to the duration of testing, often necessitates the use of B-scan ultrasound (BSUS). This study investigated whether PHOMS are hyperreflective on BSUS and if BSUS can differentiate PHOMS from ODD.

Understanding the emergence of complex biochemical systems, such as protein translation, is a great challenge. Although synthetic approaches can provide insight into the potential early stages of life, they do not address the equally important question of why the complex systems of life would have evolved. In particular, the intricacies of the mechanisms governing the transfer of information from nucleic acid sequences to proteins make it difficult to imagine how coded protein synthesis could have emerged from a prebiotic soup.

A considerable amount of work has been carried out on the biology of learning and memory acquisition, and retention [1-6]; however, little is known regarding how the information is written in the brain [7-9]. It is notable that in the Neuron Theory postulated by Santiago Ramón y Cajal [10], neurons were conceived to form a contiguous instead of a continuous structure. They were physically separated but could function through their connections by synapses [11].

The traditional understanding of brain function has predominantly focused on chemical and electrical processes. However, new research in fruit fly (Drosophila) binocular vision reveals ultrafast photomechanical photoreceptor movements significantly enhance information processing, thereby impacting a fly's perception of its environment and behaviour. The coding advantages resulting from these mechanical processes suggest that similar physical motion-based coding strategies may affect neural communication ubiquitously.

Introduction: Virtual reality (VR) is a rapidly evolving technology that has been shown to improve pain severity in different disease states, including cancer. To date, VR pain studies have used off-the-shelf products for pain distraction. What are user preferences for VR content to mitigate cancer pain?.
