We describe here the use of a pH-sensitive green fluorescent protein variant, pHluorin, to study the spatio-temporal dynamics of axon guidance receptors trafficking at the cell surface. The pHluorin-tagged receptor is expressed both in cell culture and in vivo, using electroporation of the chick embryo.

This protocol describes a bioprinting methodology using an automated robotic depositing system that incorporates etched topographical guidance cues with the precision deposition of a cell bearing hydrogel bioink. The printed cells are directly delivered to the etched features and are able to sense and orientate with them.

Stereo-electroencephalography (SEEG) aids in localization of epileptogenic zones, however, remains relatively underutilized in the United States. The goal of this abstract is to provide a brief introduction to the technique of SEEG and further a detailed technique of using robotic assistance in the placement of SEEG electrodes.

We describe a new method for counting fishes, and estimating relative abundance (MaxN) and fish density using rotating stereo-video camera systems. We also demonstrate how to use distance from camera (Z distance) to estimate species-specific detectability.
FAQs
Depth perception comes from the instrument’s two separate optical paths, which deliver slightly different views to the two eyes. The brain can compare these views while the user examines a specimen, helping distinguish surface form and spatial relationships. This binocular arrangement is especially useful when precise positioning or manipulation matters during biological observation.
Reflected illumination is important when a specimen does not transmit light effectively. By lighting the surface rather than relying on light passing through it, the setup makes external features available for inspection. Choosing suitable illumination helps users see the specimen’s surface clearly, which supports observation of morphology in relatively large, opaque biological material.
Adjustable zoom lets the user change the scale of inspection without abandoning the same specimen. A broader view can support orientation and general sorting, whereas a closer view can support examination of smaller surface features. Selecting magnification deliberately helps balance field of view, visual detail, and the handling precision needed for dissection or manipulation.
Effective use begins by positioning and orienting the specimen so the relevant region is accessible. The user then selects suitable illumination and magnification while maintaining the viewing position needed for depth perception. This sequence supports controlled inspection and manipulation because the specimen’s arrangement, visible surface, and scale are matched to the immediate biological task.
Biologists can apply this guidance when examining insects, plant structures, tissues, and other specimens that are large enough for low-magnification inspection. The method is useful for dissection, sorting, and manipulation, where users must both observe morphology and handle material accurately. Its value therefore extends beyond viewing to practical tasks that depend on stable spatial perception.
The quality of morphological data depends partly on how consistently the specimen is positioned, illuminated, and viewed. When these factors are selected deliberately, users can inspect surface features at an appropriate scale and relate observations to specimen structure. Guidance therefore improves visual access and can enhance the quality and precision of observations recorded during biological work.
