This protocol describes the design and surgical implantation of a head-restraining mechanism to monitor neuronal activity in sub-cortical brain structures in alert rats. It delineates procedures to isolate single neurons in the juxtacellular configuration and to efficiently identify their anatomical locations.

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Positive Reinforcement Studies

2023
Researchers study learning of a behavior through the use of operant conditioning. This type of learning involves associating the behavior with a consequence, which is a reward or punishment. If the consequence is a reward, it leads to reinforcement of the desired behavior. One type of reinforcement approach is positive reinforcement, where the behavior is rewarded with an artificial, natural, or social reinforcer. Studies using positive reinforcement as a tool can help tease out important...

Muscles that Move the Head

2024
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending. The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Concussion presents the most common type of traumatic brain injury. Therefore, a repetitive concussive animal model, which replicates the important features of an injury in patients, may provide a means to study concussion in a rigorous, controlled, and efficient manner.
FAQs
Head location describes where the head is positioned, whereas orientation describes its angle or directional alignment. Examining both measures helps distinguish a change in position from a change in orientation, or identify when both occur together. This distinction is useful for studying movement, posture, orientation toward stimuli, and coordination between head and body.
Recording changes over time preserves the dynamics of behavior rather than reducing movement to a single position or angle. These time-resolved data can show how head movements unfold during locomotion, posture maintenance, sensory tasks, or motor tasks. They also support analysis of coordination and responses as biological events occur.
Video tracking, reflective markers, and motion sensors provide different ways to record head position and orientation during an experiment. The resulting measurements can be converted into changes in location and angle over time. Using these recording approaches allows researchers to obtain quantitative behavioral data for studying movement, posture, sensory responses, and motor control.
A basic workflow begins by recording head movements with video tracking, reflective markers, or motion sensors. Researchers then convert the recorded changes in location and angle into time-resolved measurements. Those measurements can be examined alongside behavioral tasks to evaluate orientation, movement, posture, head-body coordination, or responses to sensory and motor conditions.
The measurements can quantify locomotion, spatial behavior, posture, and orientation toward stimuli. They can also reveal how head and body movements are coordinated during sensory or motor tasks. Because the data preserve changes in position and angle over time, researchers can examine behavioral patterns rather than relying only on qualitative observations.
In neuroscience and behavioral biology, head position monitoring provides measurable behavioral information for studying vestibular function, spatial behavior, locomotion, and neural control. Researchers can relate recorded head movements to sensory and motor tasks, then use the resulting measurements to evaluate posture, orientation, and coordination. Standardized recordings also improve experimental reproducibility.
