Installation of Optical Windows in the Brain of Transgenic Mice to Image Neural Activities
내레이션 대본
Begin with an anesthetized, genetically altered mouse with its head secured in a head-holding adaptor.
The mouse brain expresses a fluorescent protein that enables the detection of neural activities.
Shave and sequentially sterilize the scalp before cutting it open.
Remove connective tissue to expose the skull.
Mark the target areas and apply a layer of glue.
Use a microdrill to thin the skull on the marked area.
Remove the piece of the skull to expose the brain.
Apply artificial cerebrospinal fluid to keep the brain moist.
Install an optical window in the area and seal it with glue, which provides a base for the cement attachment.
Apply black dental cement to block the light.
Repeat the procedure on the other side of the skull.
Allow the animal to recover.
To image neural activity, place the secured anesthetized mouse under the microscope and acquire images.
