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 barr...

Introduction: Barrel cortex of rodents is responsible for sensory information processing from muzzle whiskers. Locus coeruleus (LC) as the main source of norepinephrine (NE) in the cortex, is effective on the sensory information processing. Methods: Rats were divided to 2 groups. One group underwent sensory deprivation (P4) and the other group served as control and did not undergo sensory d...

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, exterac...

Background: About 50% of stroke patients suffer from the disorder of consciousness with such adverse effects as sensory deprivation. The provision of a care program consisting of simple and safe stimulations can prevent sensory deprivation and improve the patient’s sensory function. Aim: This study aimed to determine the effect of structured sensory stimulation program on the sensory function o...

48 university students similar to those used in experiments on sensory deprivation (SD) were surveyed to determine their knowledge about sensory deprivation, their acknowledged reasons for volunteering to be in sensory deprivation experiments, and their previous history of unusual appearing (SDlike) experiences. The responses indicated considerable knowledge of sensory deprivation, very "active...

  TBS (Theta Burst Stimulation) and PBs (Primed Bursts) are among effective tetanic stimulations for induction of LTP in hippocampus. Recent studies have indicated that TBS is effective in LTP induction in layer III synapses of neocortex, only if applied to layer IV. However, the possibility of neocortical LTP induction using PBs, has not yet been investigated. Sensory deprivation greatly influ...
