OBJECTIVE The Cox maze procedure was introduced in 1987 for the treatment of atrial fibrillation. This study evaluated the predictors of late atrial fibrillation recurrence in 276 consecutive patients who underwent this procedure at our institution. METHODS From 1987 through June 2003, 276 patients (79 female and 197 male patients; mean age, 55 +/- 11 years) underwent the Cox maze procedure. ...

Twenty-four people learned three versions of a room-sized maze: a wire-frame desktop virtual environment (VE), a normal surface-rendered desktop VE, and a real-world maze. Differences among the mental representations formed from each environment were measured with pointing and distance estimation tasks in a real-world version of each maze. People were more accurate at pointing after having lear...

Imagine you are trapped in a maze of caves. All you have is an old rusty compass and barely enough light to read it. Howmuch inaccuracy can you allow to ensure that you can leave the maze? Or you are walking in a maze of hedgerows that are on the whole orthogonal. Can you find the exit by counting left and right turns? We consider the problem of escaping from an unknown polygonal maze under lim...

The performance in a radial-arm maze of two groups of rats with restricted access to extra-maze visual cues was studied. One group received extensive exposure to the visual environment of the maze, whereas the second group was never exposed to the environment, aside from their experience in the maze itself. Spatial exposure resulted in a slightly improved ability to discriminate between previou...

Previous findings show that rats in a maze tend to choose the shortest path reach food. But it is not clear whether this choice based on length solely, or some other factors. The aim of experiment was investigate which factor dominates behavior maze: (longer and shorter), time effort (more less strenuous). involved 40 mice (4 groups), learning with two paths. Each group went through only one si...

Brain Computer Interfaces are specialized systems that allows users to control computer applications using their brain waves. Initially, BCI were mostly used in medical field. But after some research and thanks consumer-grade electroencephalography (EEG) devices, many opportunities opened outside of the One particular area is gaining more evidence due arrival devices games, as it user-friendly ...

Maze problems represent a simplified virtual model of real environments that can be used for developing core algorithms of many real-world application related to the problem of navigation. However, the best achievements of Learning Classifier Systems (LCS) in maze problems are still mostly bounded to non-aliasing environments, while LCS complexity seems to obstruct a proper analysis of the reas...

We tested whether mice can represent locations distributed throughout three-dimensional space, by developing a novel three-dimensional radial arm maze. The three-dimensional radial maze, or "radiolarian" maze, consists of a central spherical core from which arms project in all directions. Mice learn to retrieve food from the ends of the arms without omitting any arms or re-visiting depleted one...
