Eye movement monitoring (or eye tracking) reveals where in space the eyes linger, when and for how long. Here, we demonstrate how eye tracking can be used to investigate the integrity of memory in multiple participant populations, without requiring verbal, or otherwise explicit, reports.

2025
This video demonstrates imaging and quantification of protein aggregates in genetically modified Drosophila brains. Brains are fixed, washed, and treated with an antifading agent before mounting. Images are captured using a confocal microscope and quantified to observe the transmission of mutant protein aggregates.

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints. Here are some common anatomical movements: Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...

In vivo Quantification of G Protein Coupled Receptor Interactions using Spectrally Resolved Two-photon Microscopy

By employing a spectrally resolved two-photon microscopy imaging system, pixel-level maps of Förster Resonance Energy Transfer (FRET) efficiencies are obtained for cells expressing membrane receptors hypothesized to form homo-oligomeric complexes. From the FRET efficiency maps, we are able to estimate stoichiometric information about the oligomer complex under study.
FAQs
Measurements can focus on several distinct behaviors, including displacement, diffusion, transport rate, and accumulation. Displacement describes a change in position, whereas diffusion reflects movement through cellular space. Transport rate emphasizes how quickly a protein is moved, and accumulation indicates increased presence in a particular location. Separating these behaviors helps researchers interpret intracellular organization more precisely.
Protein redistribution can change when cells receive signals or when proteins assemble into complexes. Quantifying location over time can therefore show whether a protein responds to a cellular cue, joins a structure, or changes its compartmental distribution. These observations connect movement data with mechanisms of signaling, complex assembly, and the organization of cellular activities.
A protein's changing location can indicate how it reaches an organelle or leaves one compartment for another. Measuring these changes helps researchers examine protein trafficking and the mechanisms that maintain cellular organization. The resulting data can reveal whether a protein becomes concentrated, redistributed, or transported in relation to organelle function and broader changes in cell biology.
A typical workflow begins by labeling or otherwise detecting the protein, followed by recording its location through imaging or fractionation. Researchers then compare measurements over time or across cellular compartments and calculate changes such as displacement, diffusion, transport rate, or accumulation. This sequence converts observed protein behavior into quantitative data suitable for biological interpretation.
Imaging captures where a detected protein is located, allowing changes in position or distribution to be followed over time. Fractionation instead separates cellular compartments so researchers can assess where the protein is present within the cell. These approaches provide complementary ways to examine movement, trafficking, and accumulation, depending on whether spatial dynamics or compartment distribution is the main focus.
Protein movement quantification is useful when development or disease may alter cellular organization, signaling, or trafficking. Tracking redistribution can show how protein behavior changes during developmental processes or under disease-associated conditions. Such measurements help connect altered protein localization with cellular health and provide quantitative evidence for mechanisms that may not be apparent from a single static observation.
