This video demonstrates the brain's neural activity recording through an optical window in transgenic mice. The mice express a fluorescent protein that enables the detection of neural activities. A small portion of the skull is carefully removed to install an optical window, and the skull is then covered with black cement to block light before imaging.

FAQs
The bearing ends must transfer the supported load into the surrounding wall, so they require adequate contact and bearing length. If the ends do not sit correctly, the load may not distribute as intended through the masonry. Checking this dimension during lintel installation helps maintain stability and reduces the risk of cracking, settlement, or local failure around the opening.
A lintel should be aligned with the wall and installed at the intended level so its support is distributed consistently across the opening. Misalignment or uneven placement can create unintended load concentrations and may affect the surrounding masonry. Careful checking is therefore important at doors, windows, and other openings where movement or cracking could impair the wall’s performance.
Lintels may be made from reinforced concrete, steel, masonry, or timber, and the selected design determines the member being placed above the opening. Because these materials represent different design options, installation must follow the specified arrangement for the project. The material choice should therefore be considered together with sizing, bearing ends, alignment, and the wall construction.
Temporary support helps maintain stability while the permanent lintel is being placed and the surrounding construction is not yet fully supported by the completed arrangement. This is particularly relevant when work alters an existing wall or creates an opening during refurbishment. Providing the required temporary support reduces the chance of movement during installation and protects the wall from instability.
A practical sequence includes confirming the required lintel size and material, preparing the opening and its supports, positioning the member with adequate bearing at both ends, and checking its alignment and level. Temporary support should be provided where required during the work. These checks address the main installation conditions that influence how the wall carries loads after completion.
Lintel installation is used above openings such as doors and windows, as well as other wall openings that interrupt continuous masonry. It applies both to new construction and to refurbishment projects. In each setting, the work must accommodate the surrounding wall and maintain suitable support at the ends so the completed opening does not compromise wall stability.
Correct installation helps the wall perform as intended around an opening and can prevent cracking, settlement, and failure. These outcomes depend on several related conditions, including suitable sizing, adequate bearing length, accurate alignment, correct level, and appropriate temporary support. Reviewing all of these factors provides a more reliable result than focusing only on placing the lintel above the opening.
