Pdf crossmodal plasticity is a striking adaptive feature of the brain, whereby the loss of one sensory modality induces cortical reorganization that. Crossmodal plasticity revealed by electrotactile stimulation of the. Crossmodal plasticity is an adaptive phenomenon, in which portions of a damaged sensory region of the brain are taken over by unaffected regions. The reorganization of the neural network is greatest following longterm sensory deprivation, such as congenital blindness or prelingual deafness. Downward crossmodal plasticity in singlesided deafness.
This phenomenon is referred to as crossmodal plasticity, which is generally considered to be a type of compensation where the resource in the deprived sensory cortex is recruited to enhance other intact sensory systems to compensate for a sensory absence kupers and ptito, 2014. Crossmodal plasticity and its implications for cortical development and function. Crossmodal plasticity for the spatial processing of sounds. It is now well described that loss of a sensory modality leads to widespread compensatory plasticity across brain areas, which in some cases includes the primary sensory cortices. Are supramodality and crossmodal plasticity the yin and. However, little is known on the neuroplastic changes in restoring the deprived sense. Pdf when the brain is deprived of input from one sensory modality, it often compensates with supranormal performance in one or more of the intact. Wellestablished crossmodal plasticity, the ability of the brain to reorganize and make functional changes to compensate for a sensory deficit. This process, known as crossmodal plasticity, has been widely studied in individuals with vision or hearing loss.
