The Thoracic Cage: Sternum
0 Views •
2023
The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12). The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid process.

The Thoracic Cage: Ribs
0 Views •
2025
Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages. Parts of a Typical Rib A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal facet...

Eye Movement Monitoring of Memory

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,...
FAQs
Implanted electrodes measure neural signals while wireless telemetry transmits those signals as the animal moves within the enclosure. Researchers can therefore align electrophysiological activity with exploration, rest, or sleep as those states occur. This pairing preserves the timing between spontaneous behavior and brain activity, rather than separating neural measurements from the actions accompanying them.
Its value comes from preserving behavior that may be altered by handling or restraint. In a Free Movement Cage, animals can explore, rest, or sleep while measurements continue, allowing researchers to study neural activity and physiology in a more behaviorally valid setting. This is especially relevant when the research question concerns spontaneous actions rather than responses produced under imposed restriction.
Recording across exploration, rest, and sleep lets researchers compare neural activity and physiology across naturally occurring conditions. The same enclosure can also support studies of sleep-wake states and circadian rhythms, so measurements can be related both to immediate behavior and to recurring daily patterns. This broader temporal context helps show whether findings are state-specific or associated with spontaneous activity.
A typical setup combines the enclosure with implanted electrodes or a wireless telemetry system, together with measurements of behavior, neural activity, or physiology. The animal remains in the cage while researchers record during exploration, rest, or sleep. These components make it possible to connect electrophysiological signals with the animal’s ongoing behavioral state under minimally restricted conditions.
Researchers allow the animal to move within the enclosure while recording neural activity, physiology, or behavior. With implanted electrodes or wireless telemetry, measurements can continue as the animal explores, rests, or sleeps. The resulting recordings are examined in relation to those spontaneous actions and states, creating a direct behavioral context for electrophysiological measurements.
Free Movement Cage studies can address locomotion, sleep-wake states, circadian rhythms, sensory processing, and responses to drugs or neural interventions. Its value varies with the measurement goal: recordings may be linked to movement, rest, sleep, or physiological changes. This makes the approach useful when researchers need neural data interpreted alongside behavior rather than collected in isolation.
