A rabbit head holder for attachment to a conventional stereotaxic machine

Area of Science:

• Neuroscience
• Surgical Instrumentation
• Animal Models

Background:

• Stereotaxic surgery requires precise head fixation for accurate targeting.
• Existing methods may lack stability or reproducibility for specific animal models like rabbits.

Purpose of the Study:

• To introduce and validate a new stereotaxic head-holding device for rabbits.
• To ensure accurate and reproducible probe placement in the rabbit brain.

Main Methods:

• The device utilizes orbital clamps and an upper molar plate for counter-thrust anchorage.
• The head-holder assembly pivots on a U-frame attached to a standard stereotaxic apparatus.
• Sagittal plane rotation is facilitated by the pivoting mechanism.

Main Results:

• The device provides rigid head support, validated through extensive experimentation.
• Accurate reproducibility of stereotaxic probe placement relative to bregma was confirmed.
• The device is effective within limited ranges of animal size.

Conclusions:

• This novel head-holding device offers a reliable solution for stereotaxic procedures in rabbits.
• It enhances experimental reproducibility and accuracy in neuroscientific research.
• The design ensures stable fixation, crucial for precise targeting of brain structures.
