Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
An important issue in spatial memory is the learning of abstract representations suitable for navigation planning. To address this problem, we have already developed a planning system inspired by the columnar organization of the mammalian cortex [1]. This model provides a neuromimetic architecture capable of learning topological spatial representations and planning goal-directed actions. The work presented here deals with the ability to encode multiscale representations of the environment, in order to solve large maze tasks. This is shown by validating the model on a multiscale version of the Tolman & Honzik's detour task [2]. Simulation results demonstrate that the performances of the planning system are invariant with respect to the scale of the maze. A series of statistical analyses is provided to characterise the neural activities subserving spatial planning. It is shown that the structural properties of the environment are encoded by the discharges of the location-selective neurones of the model. Complementing this purely spatial coding, the activity of another class of neurones in the model integrates both spatial and reward-dependent information suitable for navigation planning. © 2010 Springer-Verlag.
