We discuss a novel method forviewpoint-rotation of visual stimuli, and demonstrate using a mirror stereoscopethe three-dimensional percept of rotation-in-depth. The technique can be used to investigate the role of stereoscopic cues in encoding viewpoint-rotated figures.

Video-oculography is a very quantitative method to investigate ocular motor performance as well as motor learning. Here, we describe how to measure video-oculography in mice. Applying this technique on normal, pharmacologically-treated or genetically modified mice is a powerful research tool to explore the underlying physiology of motor behaviors.

The extracellular matrix (ECM) is a network of molecules that provide a structural framework for cells and tissues and helps facilitate intercellular communication. Three-dimensional cell culture techniques have been developed to more accurately model this extracellular environment for in vitro study. While many cell processes during migration through 3D matrices are similar to those required for movement across rigid 2D surfaces, including adherence, migration through ECM also requires cells...

Collagen is a core component of the ECM, and provides essential cues for several cellular processes ranging from migration to differentiation and proliferation. Provided here is a protocol for embedding cells within 3D collagen hydrogels, and a more advanced technique for generating randomized or aligned collagen matrices using PDMS microchannels.

The key mechanism is binocular disparity, the small difference between the left-eye and right-eye views. When each view reaches its intended eye, the brain compares those perspectives and constructs a representation with depth. In medical imagery, this processing makes the relative locations of anatomical structures and other visible elements easier to interpret.
Two cameras or rendered image streams provide the paired perspectives needed to represent spatial relationships. Each stream shows the same scene from a slightly different viewpoint, preserving the visual difference that supports depth perception. This arrangement can make the position of anatomy, instruments, and other structures more understandable during medical visualization and learning.
The display or viewing system must deliver the separate image streams to the left and right eyes. This assignment allows the brain to combine the views rather than treating them as unrelated images. The resulting three-dimensional representation supports clearer interpretation of spatial information, which is particularly relevant when medical scenes contain closely related anatomical structures or instrument positions.
In surgical visualization, depth perception can help clinicians interpret the relationship between anatomy and instruments more clearly. The paired views preserve spatial information that may be important when judging where visible elements lie relative to one another. This makes the technique relevant for presenting complex operative scenes and supporting a clearer understanding of instrument position.
Stereoscopic 3D video can present anatomy and procedural scenes in a form that emphasizes spatial relationships. Learners may use the resulting depth cues to understand how structures are positioned and how instruments relate to them. Its educational value therefore extends across anatomical education and procedural training, where interpreting three-dimensional arrangements is central to learning.
The method can communicate complex spatial information, including the relative arrangement of anatomical structures and the position of instruments within a scene. By making these relationships easier to interpret, it can support communication among clinicians and learners. Its relevance is not limited to visualization alone, because the same spatial representation can aid explanation, training, and shared understanding.
