The growth plate is a cartilaginous region in children's long bones where longitudinal growth occurs. When injured, bony tissue can form and impair growth. We describe a rat model of growth plate injury that leads to bony repair tissue, allowing the study of repair mechanisms and growth plate regeneration strategies.
FAQs
Predetermined coordinates identify the intended anatomical target, while openings or channels establish the instrument’s entry point and trajectory. These features constrain movement during placement, helping the researcher reproduce the same approach across procedures. In neuroscience experiments, that consistency supports more reliable positioning of electrodes, cannulas, optical fibers, or other implanted components.
Rigid fixation limits movement between the guide plate and the experimental setup during surgery. Maintaining a stable reference helps preserve the planned trajectory and reduces unintended shifts near surrounding tissue. This stability is especially important when a procedure must accurately reach a defined brain location or support repeated investigations over time.
Accuracy depends on how precisely the plate is positioned and how its coordinates, openings, or channels constrain instrument movement. A stable plate provides a consistent reference for entry and trajectory, whereas poorly controlled positioning can reduce targeting consistency. These design and placement features directly affect the reproducibility of neural recording, stimulation, delivery, and imaging procedures.
The guide plate is first fixed to the skull or an experimental apparatus in the planned position. Researchers then use its predetermined coordinates, openings, or channels to guide an instrument toward the target. Depending on the study, the guided component may be an electrode, cannula, optical fiber, or another device used for recording, stimulation, delivery, or imaging.
A guide plate can direct the placement of electrodes for neural recording or stimulation, cannulas for drug delivery, and optical fibers or other devices for imaging studies. Its constrained entry points and trajectories help place these components consistently at defined anatomical targets, supporting experiments that require controlled access to brain structures.
Because a guide plate establishes a fixed and reproducible relationship between the experimental apparatus and the anatomical target, it can help maintain consistency across investigations conducted over time. This supports longitudinal studies of brain structure and function, where comparable device placement and reduced movement are important for interpreting changes across repeated observations.
