context the current study aimed to review research articles concerning cortical representational plasticity following the manipulations of inputs. evidence acquisition this review article compromised previous studies in pubmed, google scholar and scientific information databases according to the keywords since 1988. results ca1 neurons depolarization paired with ca3 presynaptic input result in ...

Adrenergic receptors have an important role in neural excitability and synaptic plasticity. Despite a lot of studies on these receptors, their exact role in brain disorders accompanied with hyperexcitability has not been determined. There are also controversies on their role in synaptic plasticity. In this review article, the important studies done in this regard have been reviewed to achieve a...

introduction: neuro-plasticity is the neuronal system ability to modify and recover itself after the occurrence of impairment and injuries. following the abolition of a sensory modality, modifications will be applied to other modalities and their cortical function in a way that the processing of these modalities not only will happen in their own specific cortical area, but also in those areas t...

hippocampal neural stem/progenitor cells (hipp-ns/pcs) of the adult mammalian brain are important sources of neuronal and gial cell production. in this study, the main goal is to investigate the plasticity of these cells in neuronal/astroglial differentiations. to this end, the differentiation of the hipp-ns/pcs isolated from 3-month-old wistar rats was investigated in response to the embryonic...

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...

We present a simplified phase model for neuronal dynamics with spike timing-dependent plasticity (STDP). For asymmetric, experimentally observed STDP we find multistability: a coexistence of a fully synchronized, a fully desynchronized, and a variety of cluster states in a wide enough range of the parameter space. We show that multistability can occur only for asymmetric STDP, and we study how ...
