Overview of Bilateral Hemispherectomy Procedure. Step-by-step description follows below.
A. Mouse must be anesthetized and secured in the stereotaxic apparatus.
B. The scalp is removed to enable access to the skull.
C. The skull is fully exposed with all overlying residual tissue removed.
D. The lateral edges of the skull are drilled in a pear shape, taking care not to puncture the underlying brain.
E. The causal and rostral midline skull is cut, to release the skull cap.
F. See procotol for complete details. Briefly, the skull cap is removed to create a window and fully expose the dorsal view of the brain. The superficial cortex is removed around the edge and then middle of the window. Brain tissue is removed from the anterior portion of the window to expose the rostral portion of the trigeminal ganglia. Remove the brain tissue over the midline. Avoid the caudal midline to prevent damage to brainstem. Finish removing brain from over the TGs.
G. After clotting and clot removal the TG can be visualized for imaging.
