The Stereotaxic Manual Device is a precision instrument designed for accurate targeting of specific brain regions in rodent neuroscience research. Utilizing anatomical landmarks including bregma, lambda, sagittal suture, external auditory meatus, and tooth bar as reference points, the device enables precise three-dimensional positioning through X/Y/Z coordinate manipulation using main and vernier scales. The triangular guide rail system with universal contact points facilitates rapid positioning and lateral or longitudinal movement adjustments.
Available in single and double arm configurations for both mouse and rat applications, the device employs screw rod and rolling mechanisms rather than traditional metal-to-metal grinding transmission to maintain long-term stability and accuracy. The system accommodates various experimental tools including electrodes, injection needles, cannulas, and optical fibers, making it compatible with optogenetics, two-photon imaging, endogenous brain imaging, fiber optic recording, and electrophysiology systems. The incisor clamp is positioned 3.3±0.4mm below the centerline connecting left and right ear bars for standardized animal positioning.
How It Works
The stereotaxic principle relies on establishing a standardized coordinate system using consistent anatomical landmarks on the skull surface. The device positions the animal's head in a fixed orientation using ear bars and an incisor clamp, creating a reproducible reference frame. Bregma, the intersection of the coronal and sagittal sutures, serves as the primary zero-point coordinate, with lambda and other landmarks providing additional reference verification.
Three-dimensional positioning is achieved through mechanical manipulation arms that move along X (medial-lateral), Y (anterior-posterior), and Z (dorsal-ventral) axes. Main scales provide coarse positioning while vernier scales enable fine adjustments for submillimeter accuracy. The triangular guide rail system ensures smooth, precise movement while universal contact points accommodate various experimental tools and maintain alignment during positioning.
The screw rod and rolling mechanism transmission system eliminates the wear and backlash associated with traditional metal-to-metal grinding systems, preserving long-term accuracy. Once target coordinates are calculated from stereotaxic atlases, the manipulator arms guide instruments to the precise brain location for injection, recording, or other experimental procedures.

Practical Tips
Verify zero positions on all three axes before each experimental session using known reference points.
Why: Mechanical systems can experience minor shifts that affect coordinate accuracy over time.
Clean guide rails with appropriate solvents after each use and inspect the rolling mechanism for debris accumulation.
Why: Contamination can affect smooth movement and positioning precision of the manipulation arms.
Always verify bregma identification by cross-referencing with lambda and sagittal suture landmarks before target calculation.
Why: Multiple landmark confirmation reduces coordinate errors and improves targeting reproducibility.
Allow anesthetized animals to reach stable physiological parameters before beginning stereotaxic positioning.
Why: Respiratory and cardiovascular stability prevents movement artifacts during precise coordinate targeting.
Secure the stereotaxic frame to a vibration-isolation table or stable surface before procedures.
Why: Any movement during targeting can result in coordinate errors and compromise experimental accuracy.
If positioning becomes difficult, check for proper ear bar placement and ensure equal pressure on both sides.
Why: Uneven head restraint can distort skull anatomy and affect coordinate system alignment.
Record actual coordinate positions achieved during procedures for verification against calculated targets.
Why: Documentation enables post-procedure verification and helps identify systematic positioning errors.
Periodically lubricate the screw rod mechanism according to manufacturer specifications to maintain smooth operation.
Why: Proper lubrication prevents mechanical binding and preserves the precision of fine positioning adjustments.
