WebNational Center for Biotechnology Information WebMay 29, 2015 · The problem is thereby reduced to efficiently computing an indicator grid for the boundary cells. If we characterize a boundary cell as one that is adjacent to at least one NoData cell (where "NoData" includes hypothetical cells that would lie beyond the edges of the grid itself), then the solution evidently requires a "focal" or neighborhood ...

WebOct 9, 2013 · However, since the boundary condition for cells near the lower or upper side is different from that for the cell around the center part of a honeycomb, some local imperfections can be created naturally by the compression process. As a result, the mode of deformation could be changed.
WebMar 7, 2024 · In follow-up studies, the team plans to test the theory that boundary and event cells activate dopamine neurons when they fire, and that dopamine, a chemical that sends messages between cells ... WebBoundary cells, which are found in brain areas that provide input to the hippocampus, increase their firing at a preferred distance from a specific boundary. As such, a small number of boundary cells can provide sufficient information to cause place cells to fire in their preferred locations.
Web11 hours ago · Boundary Vector Cells (BVCs) are neurons which encode an animal's location with respect to boundaries. Here we report the first objective characterisation of the prevalence and spatial tuning of BVCs in the Subiculum. Manipulations of boundary geometry reveal two novel features of BVC firing. WebThe wall boundary condition in Eq. ( 8.1) can be implemented for a cell-centered unstructured scheme in a way similar to that on structured grids. If the boundary cell is …
WebBoundary scan is a special type of scan path with a register added at every I/O pin on a device. Although this requires special extra test latches on these pins, the technique offers several important benefits, the most obvious being that it allows fault isolation at the component level.
WebJul 22, 2024 · There is a difference in the percentage of cells undergoing mitosis in boundaries (19%) versus other hindbrain territories (atoh1a-positive cells, 11.5%; neurog1-positive cells, 8.5%) at 26 hpf; the boundary cell population dramatically changes its proliferative behavior after the offset of Yap/Taz-activity (5.7% at 40 hpf).
