Correct option is A
Stereotaxic surgery (also called stereotactic surgery) is a precise surgical technique that uses a three-dimensional coordinate system to locate and target specific structures deep within the brain. A stereotaxic apparatus holds the head in a fixed position and uses anatomical landmarks to calculate exact coordinates, allowing researchers or surgeons to precisely position electrodes, cannulae, or other devices at specific brain locations. This method is essential for reaching deep brain structures accurately.
Information Booster:
1. Coordinate System: Uses a stereotaxic atlas with standardized coordinates based on reference points like bregma (skull landmark)
2. Three-Dimensional Positioning: Allows precise targeting along anterior-posterior, medial-lateral, and dorsal-ventral axes
3. Applications: Used for creating lesions, implanting electrodes, delivering drugs, or stimulating specific brain regions
4. Clinical Uses: Deep brain stimulation for Parkinson's disease and other disorders relies on stereotaxic techniques
5. Accuracy: Can position devices within millimeters of target structures even in deep brain regions
Additional Knowledge:
-Aspiration Lesions (B): Involves removing surface brain tissue using suction, not precise deep positioning
-Transcranial Magnetic Stimulation (C): Non-invasive surface stimulation using magnetic fields, doesn't involve positioning devices in brain depth
-Deoxyglucose Technique (D): Imaging method showing metabolic activity, not a positioning technique
