Rats learned to discriminate between two degrees of roughness, detecting the stimuli only with their vibrissal system. After bilateral trimming of the vibrissae, performance abruptly dropped to chance levels and remained ...

The aim of this paper is to further explore the usefulness of the two-dimensional complexity-entropy causality plane as a texture image descriptor. A multiscale generalization is introduced in order to distinguish between ...

When rats acquire sensory information by actively moving their vibrissae, a neural code is manifested at different levels of the sensory system. Behavioral studies in tactile discrimination agree that rats can distinguish ...

Background: Rats distinguish objects differing in surface texture by actively moving their vibrissae. In this paper we characterized some aspects of texture sensing in anesthetized rats during active touch. We analyzed the ...

We studied primary-somatosensory cortical plasticity due to selective stimulation of the sensory periphery by two procedures of active exploration in adult rats. Subjects, left with only three adjacent whiskers, were trained ...

Understanding and describing the spatial characteristics of soil surface microrelief are required for modelling overland flow and erosion. We employed the multifractal approach to characterize topographical point elevation ...

The Regional Integration Agreements surround the international economy as an alternative to total liberalization of markets. Latin America was not astonished with the resurgence of the post-cold war regionalism. Regarding ...
