The dorsomedial and dorsolateral prefrontal cortices (dmPFC and dlPFC) together support cognitive control, with dmPFC responsible for monitoring performance and dlPFC responsible for adjusting behavior. The dlPFC contains a topographic organization that reflects complexity of control demands, with more anterior regions guiding increasingly abstract processing. Recent evidence for a similar grad...

This paper addresses the automation of georeferencing topographic maps for the operational acquisition of spatiotemporal data on urban growth. The achieved automation of this process helps to overcome some issues and hindrances of costly manual data preparation and, thus, enables high resolution monitoring and GIS-based analyses of urban dynamics on a regional and, even, national level. Despite...

In this paper, under the efficient coding theory we propose a computational model to explore the intrinsic dimensionality of scene perception. This model is hierarchically constructed according to the information pathway of visual cortex: By pooling together the activity of local low-level feature detectors across a large regions of the visual fields, we build the population feature representat...

The mapping function w = k log(z + a) is a widely accepted approximation to the topographic structure of primate V1 foveal and parafoveal regions. A better model, at the cost of an additional parameter, captures the full field topographic map in terms of the dipole map function w = k log[(z + a)/(z + b)]. However, neither model describes topographic shear since they are both explicitly complex-...

Raster-based topographic maps are commonly used in geoinformation systems to overlay geographic entities on top of digital terrain models. Using compressed texture formats for encoding topographic maps allows reducing latency times while visualizing large geographic datasets. Topographic maps encompass high-frequency content with large uniform regions, making current compressed texture formats ...

Topographic and overcomplete representations of natural images/videos are important problems in computational neuroscience. We propose a new method using both topographic and overcomplete representations of natural images, showing emergence of properties similar to those of complex cells in primary visual cortex (V1). This method can be considered as an extension of model in Hyvärinen et al. [T...
