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

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,...

Here, we present a protocol for studying orthodontic tooth movement (OTM), serving as a suitable model for investigating the mechanisms of bone adaptation, root resorption, and the response of bone cells to mechanical stimuli. This comprehensive guide provides detailed information on the OTM model, micro-computed tomography acquisition, and subsequent analysis.
FAQs
Sensory systems detect environmental cues and internal neural circuits integrate that information before motor neurons activate muscles. These coordinated signals regulate posture, speed, turning, and orientation rather than producing movement as an isolated muscle response. Studying the resulting behavior helps researchers relate visible locomotor changes to specific neural mechanisms and to alterations in nervous-system function.
Researchers can examine walking, climbing, flying, changes in direction, speed, posture, and orientation. Each feature reflects a somewhat different aspect of sensorimotor control. For example, turning and orientation reveal how flies respond to cues, while speed or climbing performance can indicate altered motor coordination. Measuring several features provides a broader behavioral profile than observing activity alone.
Movement changes when internal states interact with information from the environment. This relationship allows locomotor assays to examine behaviors associated with learning, circadian rhythms, courtship, and stress. Controlled observations can then distinguish changes in activity or orientation from broader changes in behavioral state, helping connect an observed response with the condition being investigated.
Genetic or pharmacological changes can modify neural or motor function, producing measurable differences in locomotor behavior. Researchers compare these changes with movement in controlled conditions to investigate how nervous-system components contribute to posture, speed, turning, or orientation. This approach links an observable behavioral outcome with an underlying biological mechanism and can also inform disease-relevant research.
A basic assay places flies under controlled conditions and records locomotor activity, including behaviors such as walking, climbing, flying, or changing direction. Researchers define the movement features relevant to the question, observe how flies respond to internal or environmental conditions, and compare the resulting patterns across experimental groups. The measurements provide behavioral outcomes for further neural interpretation.
Movement measurements are useful when a study asks how flies respond to learning, circadian rhythms, courtship, stress, or an experimental genetic or pharmacological change. Locomotor outcomes provide a direct behavioral readout that can be compared across conditions. Because Drosophila has a well-characterized nervous system and powerful genetic tools, these assays support investigations connecting behavior with neural mechanisms.
The method connects observable actions with the systems that generate them, including sensory inputs, neural circuits, motor neurons, and muscles. In behavior research, this connection helps explain how flies coordinate posture, speed, turning, and orientation. In neuroscience, movement changes offer an outcome for examining nervous-system function, including processes relevant to disease-related investigation.
