Participants were required to find objects in a virtual environment by reference either to the boundary of the environment or to landmarks within the environment.
Since the walls of the rectangular pool create the boundary of the environment, it might be argued that the hippocampal lesions were effective by making it difficult for subjects to navigate with reference to boundary cues.
Furthermore, it is possible to observe the reconversion of the molecules of NADH (blue circles) to molecules of NAD+ whenever the first hit the cell membrane (i.e., boundary of the environment).
This preference for the correct over the other, incorrect corners demonstrates that the animals can use information provided by the boundary of the environment to find the submerged platform (e.g., Pearce, Good, Jones, & McGregor, 2004; Wall, Botley, Black, & Shettleworth, 2004).
He spent his career redressing this misconception, being a structural engineer who never limited the architect but worked with him/her to push back the boundaries of the built environment.
A previously unknown cell type in the brain's cortex encodes geometric boundaries of the nearby environment, perhaps providing a frame of reference.
In 2008, we observed a third entorhinal cell type border cells which fires exclusively at edges and boundaries of the local environment (Solstad et al, 2008, Fig 2).
Mendis said Heroku has a nice API layer that allows the user to stay within the boundaries of the AnyPresence platform environment.
Then, the 2D site layout image was sent into the site importing module to generate the collision boundary of the virtual environment.
When an object reached the boundary of the virtual environment a new object was randomly generated to take its place.
