Stereotaxic surgery on rodents allows for targeted administration of drugs or electrical stimulation and recordings in awake, behaving animals. In this video presentation we will demonstrate recent procedural refinements to this long-standing procedure that successfully improved survival rate and reduced post-surgical weight loss.

Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN The Guide for the Care and Use of Laboratory Animals1 dictates that rodent survival surgery be performed aseptically. Aseptic technique utilizes specific practices that minimize the contamination of the surgical site, including patient preparation, surgeon preparation, sterilization of instruments and other supplies, and the use of a clean and controlled environment. Presurgical planning,...

Stereotaxic (or stereotactic) surgery is a method used to manipulate the brain of living animals. This technique allows researchers to accurately target deep structures within the brain through the use of a stereotaxic atlas, which provides the 3D coordinates of each area with respect to anatomical landmarks on the skull. After the skull is exposed, anesthetized animals are mounted on a specialized instrument known as a stereotaxic frame, which enables the precise placement of experimental...

The monitoring of extracellular neurotransmitter levels in distinct brain regions of freely moving animals offers insights on the link between neurotransmitter release and behavior. In vivo microdialysis coupled with electrochemical detection provides excellent anatomical and chemical resolution; and information on how basal neurotransmission is altered by pharmacological or physiological manipulations.

FAQs
Anesthesia helps control pain and reduce physiological stress while an operative procedure is performed. Its use supports careful examination, repair, removal, or modification of tissues and organs without allowing pain-related responses to interfere with the intended surgical outcome. In both veterinary care and biological research, anesthesia therefore contributes to animal welfare and more reliable observations.
These components address different sources of surgical risk. Aseptic technique limits contamination, careful tissue handling reduces unnecessary tissue damage, and hemostasis controls bleeding. Used together with appropriate wound closure, they help preserve tissue condition and support recovery. Their coordinated application is especially important when researchers need a defined biological outcome rather than effects caused by avoidable surgical complications.
Perioperative monitoring evaluates the animal’s condition before, during, and after an operation, helping identify physiological stress and supporting appropriate care. This attention is important because surgical procedures can affect animal welfare as well as experimental reliability. Monitoring therefore connects ethical practice with data quality, reducing the likelihood that uncontrolled stress or poor recovery will compromise biological interpretation.
A supported workflow includes preparing for anesthesia, maintaining aseptic conditions, performing the planned operative intervention with careful tissue handling and hemostasis, closing the wound, and providing postoperative care. Perioperative monitoring accompanies these stages to assess the animal’s condition. Organizing the procedure around these steps helps achieve the intended surgical result while limiting pain, contamination, and physiological stress.
Postoperative care supports recovery after the operative intervention and helps address pain, physiological stress, and the condition of the wound. It is not separate from experimental quality: inadequate recovery can affect animal welfare and make biological findings less reliable. Appropriate follow-up is therefore necessary when surgery is used in veterinary treatment or as part of a research model.
Animal surgery can provide models for examining anatomy, physiology, disease mechanisms, and therapeutic interventions. More specific applications include studies of injury, transplantation, and organ function. By modifying or examining tissues and organs in a controlled way, researchers can relate an operative change to biological responses, while perioperative and postoperative care help maintain ethical standards and interpretable results.
