Action images can be depicted either from the actor's first-person or an observer's third-person visual perspective. This research demonstrates that visual perspective of action imagery influences the extent to which people process actions abstractly. Two experiments presented photographs of everyday actions, manipulating their visual perspective (first-person vs. third-person), holding constant the scope and objects depicted. Subsequently, participants interpreted actions unrelated to the images. Across both experiments, viewing third-person (vs. first-person) photographs caused participants to construe the unrelated actions more abstractly. This carryover effect demonstrates a shift in processing style, sheds light on an underlying mechanism of perspective effects, and suggests that imagery is a more versatile cognitive tool than traditionally assumed.

Ever since the US Food and Drug Administration (FDA) approved the first vascular endothelial growth factor (VEGF) antagonist 2 decades ago, inhibitors of VEGF have revolutionized the treatment of a variety of ocular disorders involving pathologic neovascularization and retinal exudation. In this perspective, we evaluate the current status of anti-VEGF therapies and the real-world challenges encountered with maintaining therapeutic outcomes. Finally, we describe novel VEGF-based and combinatorial approaches that are in clinical development.

In contrast to blood-oxygenation level-dependent (BOLD) functional MRI (fMRI), which relies on changes in blood flow and oxygenation levels to infer brain activity, diffusion fMRI (DfMRI) investigates brain dynamics by monitoring alterations in the apparent diffusion coefficient (ADC) of water. These ADC changes may arise from fluctuations in neuronal morphology, providing a distinctive perspective on neural activity. The potential of ADC as an fMRI contrast (ADC-fMRI) lies in its capacity to reveal neural activity independently of neurovascular coupling, thus yielding complementary insights into brain function.

Objective: Community engagement is an increasingly important component of ancient DNA (aDNA) research, especially when it involves archeological individuals connected to contemporary descendants or other invested communities. However, effectively explaining methods to non-specialist audiences can be challenging due to the intricacies of aDNA laboratory work. To overcome this challenge, the Anson Street African Burial Ground (ASABG) Project employed a GoPro camera to visually document the process of aDNA extraction for use in community engagement and education events.

Objective: To investigate differences in the microstructure of the spinothalamic tract (STT) white matter in people with chronic neck and shoulder pain (CNSP) using diffusion tensor imaging, and to assess its correlation with pain intensity and duration of the pain.
Materials And Methods: A 3.0T MRI scanner was used to perform diffusion tensor imaging scans on 31 people with CNSP and 24 healthy controls (HCs), employing the Automatic Fiber Segmentation and Quantification (AFQ) method to extract the STT and quantitatively analyze the fractional anisotropy (FA) and mean diffusivity (MD), reflecting the microstructural integrity of nerve fibers.

Collaborative Filmmaking (CF) is a relatively new, participatory, visual research method in which participants are trained in digital filmmaking to collect and analyze their own data in the form of creative short films and to disseminate their findings through film screenings and discussions. In this comment article, we present qualitative insights that delve into the perspectives of a group of CF participants as they reflect upon their experiences using CF and the impact that the method had on them as project participants. Participants were young adult educators who used CF to explore and evaluate the process of building community support for a comprehensive sexuality education (CSE) program in rural Madagascar.
