Summary
This study presents a computer- and robot-assisted framework for precise stereotactic neurosurgery in small animals. The system enables accurate probe placement for advanced brain research and electrophysiological recordings.
Area of Science:
- Neuroscience
- Robotics
- Medical Imaging
Background:
- Stereotactic neurosurgery in small animals is crucial for brain research.
- Existing methods may lack precision and automation.
Purpose of the Study:
- To introduce a novel computer- and robot-assisted framework for stereotactic neurosurgery in small animals.
- To detail the robotic assistant and software for precise probe placement.
Main Methods:
- Developed a robotic stereotactic assistant and integrated software modules for registration, insertion control, and preoperative path planning.
- Implemented both atlas-based and image-based (CT data) planning strategies.
- Tested the framework with in vivo microelectrode insertion and electrophysiological recordings.
Main Results:
- The framework demonstrated precise robot-assisted insertion of microelectrodes.
- Electrophysiological recordings were successfully acquired in vivo.
- The system allows for mapping neural structure position to functional data.
Conclusions:
