Rats can learn a roughness discrimination using only their vibrissal system
(1989)
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 mathematical whisker: A review of numerical models of the rat׳s vibrissa biomechanics
(Elsevier, 2016-07)
The vibrissal system of the rat refers to specialized hairs the animal uses for tactile sensory perception. Rats actively move their whiskers in a characteristic way called “whisking”. Interaction with the environment ...
Neural encoding schemes of tactile information in afferent activity of the vibrissal system
(Springer, 2012-06)
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 ...
Laboratory experience for teaching sensory physiology
(American Physiological Society, 2009-05)
The major challenge in laboratory teaching is the application of abstract concepts in simple and direct practical lessons. However, students rarely have the opportunity to participate in a laboratory that combines practical ...
Texture discrimination and multi-unit recording in the rat vibrissal nerve
(BioMed Central, 2006-05)
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 ...
Discriminability measures and time-frequency features: an application to vibrissal tactile discrimination
(Elsevier Science, 2014-06)
Background: Often, the first problem that the neuroscientist must face is to determine if a specific stimulus set applied to biological system produces specific, precise and well differentiated responses. New method: In ...
Comparative study of extracellular recording methods for analysis of afferent sensory information: Empirical modeling, data analysis and interpretation
(Elsevier B.V., 2019-05)
Background: Physiological studies of sensorial systems often require the acquisition and processing of data extracted from their multiple components to evaluate how the neural information changes in relation to the environment ...
Participação do sistema histaminérgico neural na recuperação funcional de Meriones unguiculatus após lesão isquêmica unilateral encefálica
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Fisioterapia - PPGFt, 2013-02-19)
The aim of the first study was to investigate behavioural alterations and Fos expression in gerbils submitted to functional training after unilateral cerebral ischaemic injury. The behavioural procedures that were used to ...
