The Application of Tactile Experience in Urban Perception
Urban perception is the result of mutual transaction between human and environment and the process of perception is developed through the three continuous steps of “sensation”, “perception” and “cognition”. In the first step (sensorial perception), the environmental signals are received via sensorial sensors and each different sense based on its own essence, performance and ability has its own ...
متن کاملRapid Experience-Dependent Plasticity following Somatosensory Damage
Studies in nonhuman primates have provided evidence of rapid neural reorganization in somatosensory cortex after brain damage [1] and amputation [2]. Furthermore, there is also evidence of experience-dependent plasticity in both human [3-5] and nonhuman primates [6] that is induced by repetitive tactile stimulation. Given the evidence of plasticity subsequent to both neural damage and tactile e...
متن کاملStructural plasticity underlies experience-dependent functional plasticity of cortical circuits.
The stabilization of new spines in the barrel cortex is enhanced after whisker trimming, but its relationship to experience-dependent plasticity is unclear. Here we show that in wild-type mice, whisker potentiation and spine stabilization are most pronounced for layer 5 neurons at the border between spared and deprived barrel columns. In homozygote alphaCaMKII-T286A mice, which lack experience-...
متن کاملEffect of Norepinephrine depletion on induction of experience dependent plasticity in male rat barrel cortex
Introduction: Barrel cortex of rats is a part of somatosensory cortex, which receives information from facial whiskers. Vibrisectomy by sensory deprivation leads to some changes in the barrel cortex, which have been known as experience dependent plasticity. On the other hand, Norepinephrine (NE) and locus coeruleus, which is the main source of NE, influenced response properties of cortical bar...
متن کاملNeuronal response properties of somatosensory cortex (layer IV) are modulated following experience dependent plasticity in c-fiber depleted rats
Previous studies have shown that the receptive field properties, spontaneous activity and spatio-temporal interactions of low-threshold mechanical somatosensory cells in the barrel cortex are influenced by C-fibers. In this study, we examined the effect of C-fiber depletion on response properties of barrel cortex neurons following experience dependent plasticity. Methods: In this study, exte...
