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.

Source: Tamara M. Powers, Department of Chemistry, Texas A&M University The glovebox provides a straightforward means to handle air- and moisture-sensitive solids and liquids. The glovebox is what it sounds like: a box with gloves attached to one or more sides, which allows the user to perform manipulations within the glovebox under an inert atmosphere. For manipulations under inert atmospheres, chemists can choose between Schlenk or high-vacuum techniques and a glovebox. Schlenk and...

We describe an electrochemical sensor assay method for rapid bacterial detection and identification. The assay involves a sensor array functionalized with DNA oligonucleotide capture probes for ribosomal RNA (rRNA) species-specific sequences. Sandwich hybridization of target rRNA with the capture probe and a horseradish peroxidase-linked DNA oligonucleotide detector probe produces a measurable amperometric current.

This article will demonstrate how to monitor glutamine dynamics in live cells using FRET. Genetically encoded sensors allow real-time monitoring of biological molecules at a subcellular resolution. Experimental design, technical details of the experimental settings, and considerations for post-experimental analyses will be discussed for genetically encoded glutamine sensors.

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,...
FAQs
Muscle spindles monitor muscle length, whereas Golgi tendon organs encode tension. Their signals provide the central nervous system with information about the state of muscles and tendons during movement. Integrating these inputs with motor commands helps researchers examine how the nervous system regulates force, coordination, and reflex responses.
Vestibular hair cells respond to head rotation and linear acceleration. By recording vestibular responses under these conditions, researchers can examine how information about head movement contributes to balance and how it is integrated with other movement-related signals in the central nervous system. This makes vestibular activity relevant to studies of balance control and coordination.
Integration allows the central nervous system to compare sensory information about movement with visual input and the commands that produce movement. Researchers can therefore investigate how the nervous system coordinates action, detects or adjusts movement-related errors, and links incoming sensory feedback with motor control rather than examining any one signal in isolation.
Biological and engineered sensors provide complementary views of movement. Proprioceptors and vestibular hair cells report internal body-related signals, while wearable or laboratory-based tracking supplies measurable information about observed motion. Comparing these sources allows experiments to relate neural activity to movement performance, helping distinguish changes in motor control from changes in the movement itself.
Useful measurements include position, acceleration, changes in force, and signals associated with muscle length or tension. The appropriate measurement depends on the research question: position and acceleration characterize motion, whereas muscle and tendon signals reveal physiological contributions to force regulation. Together, these measurements connect observable movement with neural and muscular control.
Movement sensors support investigations of motor control, balance, coordination, and reflexes. Researchers can use the resulting measurements to relate movement performance to proprioceptive, vestibular, and central nervous system activity. The same approach also provides a way to examine altered movement patterns and sensorimotor function in neurological disorders.
Researchers can pair physiological recordings with wearable or laboratory-based motion tracking to compare neural signals with actual movement. This approach helps determine whether changes in motor commands, sensory feedback, or movement performance occur together. In neuroscience, such comparisons support studies of coordination, reflexes, balance, and movement changes associated with neurological disorders.
