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.

Anatomical Movements

2023
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,...

This report presents details of how to adopt the acromion marker cluster method of obtaining scapular kinematics when using a passive marker motion capture device. As has been described in the literature, this method provides a robust, non-invasive, three-dimensional, dynamic and valid measurement of scapular kinematics, minimizing skin movement artifact.

Electron Carriers

2019
Electron carriers can be thought of as electron shuttles. These compounds can easily accept electrons (i.e., be reduced) or lose them (i.e., be oxidized). They play an essential role in energy production because cellular respiration is contingent on the flow of electrons. Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...

The Movement of Organelles and Vesicles

In eukaryotic cells, cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...
FAQs
An electric field exerts a force on electrons, causing their net drift in the direction opposite to the field. Their motion is not unimpeded: frequent collisions with atoms interrupt and limit this drift. This relationship explains why an applied field can produce current while the material simultaneously presents electrical resistance.
Collisions with atoms oppose sustained electron drift and produce electrical resistance. As a result, electrons do not move freely through the material in response to the electric field. Accounting for these collisions helps explain why different conductive materials can support current with differing levels of conductivity and resistance.
Voltage provides the electrical condition that drives organized electron movement, while resistance describes the opposition created as electrons move through a material. Together, these concepts connect microscopic drift and collisions with measurable circuit behavior. Examining all three helps researchers interpret how a circuit conducts electricity and how its components influence current.
Electrons respond not only to electric fields but also to magnetic fields. Studying that response broadens the analysis from conduction alone to electromagnetic effects, linking electron behavior with phenomena that involve both types of fields. This perspective is important when examining electrical systems whose operation depends on interactions between electric and magnetic influences.
Researchers examine the direction of electron drift, the applied electrical conditions, and the resistance produced by collisions to interpret circuit behavior. In this context, organized electron movement represents electric current, allowing circuit design to be connected with the underlying physics of conductivity, voltage, and resistance rather than treated only as an abstract diagram.
Electron movement provides a basis for studying circuit design, semiconductor devices, sensors, energy systems, and materials research. Each area uses the relationship between electron response, conductivity, voltage, resistance, or electromagnetic effects in a different way. This broad relevance makes electron behavior a useful framework for connecting physical principles with electrical and electronic applications.
