The pressure of returning to and locating the nest after a successful foraging trip is immense in ants. To find their way back home, ants use a number of different strategies (e.g. path integration, trail following) and rely on a range of cues (e.g. pattern of polarised skylight, landmark panorama) available in their environment. How ants weigh different cues has been a question of great intere...

A functional segregation along the posterior-anterior axis of the medial temporal lobe (MTL) has been suggested. In brief, it is thought that the posterior hippocampus represents environmental detail and/or encodes space, whereas the anterior part represents the environment more as a whole and/or subserves behavior. Different phases of navigation should thus recruit different structures within ...

Navigational behavior of website visitors can be extracted from web access log files with data mining techniques such as sequential pattern mining. Visualization of the discovered patterns is very helpful to understand how visitors navigate over the various pages on the site. Currently several web log visualization tools have been developed. However those tools are far from satisfactory. They d...

Web Navigation Pattern is point comes under Web Usage Mining which shows how one can visited from one page to another i.e. it shows navigational behaviour. Mostly this pattern mining is success part of ecommerce and mobile commerce. Analysing this data will help the organizations to realize the lifetime value of their clients, and provide them with a more sophisticated structure of the web site...

Spatial navigation is a complex process requiring integration of visuoperceptual information. The present study examined how visuospatial function relates to navigational veering in Parkinson's disease, a movement disorder in which visuospatial cognition is affected by the degeneration of the basal ganglia and resulting dysfunction of the parietal lobes. We hypothesized that patients whose init...

Web usage mining is a key knowledge discovery research and as such has been well researched. So far, this research has focused mainly on databases containing access log data only. However, many real-world databases contain users profile data and current solutions for this situation are still insufficient. In this paper we have a large database containing of user profile information together wit...

Existing instruction websites record learners’ portfolios, they only collect the browsing time and homepage information, without directly provide teachers with more data for further analyzing learner behaviors. Consequently, this investigation uses the learners’ portfolio left in the e-learning environment, and adopts “data mining” techniques to establish for each cluster of learners the most a...

We constructed an 11-arm, walk-through, human radial-arm maze (HRAM) as a translational instrument to compare existing methodology in the areas of rodent and human learning and memory research. The HRAM, utilized here, serves as an intermediary test between the classic rat radial-arm maze (RAM) and standard human neuropsychological and cognitive tests. We show that the HRAM is a useful instrume...

The avian navigational system is based on an external reference, giving the home direction as a compass course. When young, inexperienced birds begin to fly, their only available orientation mechanism is a magnetic compass provided by their ability to perceive the geomagnetic field. They navigate by using this compass to record the direction of the outward journey and, by reversing this directi...
