Gene expression and plasticity in the rat auditory cortex after bilateral cochlear ablation.
CONCLUSION The plastic changes in the auditory cortex after bilateral cochlear ablation are related to the immediate early genes as well as the neural plasticity-related genes. In addition, cross-modal plasticity may play an important role in the early changes in the auditory cortex after bilateral cochlear ablation. OBJECTIVES The purpose of this study was to identify candidate genes involve...
متن کاملEvidence of multisensory plasticity: Asymmetrical medial geniculate body in people with one eye
UNLABELLED The medial geniculate body (MGB) plays a central role in auditory processing with both efferent and afferent tracts to primary auditory cortex. People who have lost one eye early in life have enhanced sound localization, lack visual over auditory dominance and integrate auditory and visual information optimally, similar to controls, despite taking longer to localize unimodal visual s...
متن کاملCompromise of auditory cortical tuning and topography after cross-modal invasion by visual inputs.
Brain damage resulting in loss of sensory stimulation can induce reorganization of sensory maps in cerebral cortex. Previous research on recovery from brain damage has focused primarily on adaptive plasticity within the affected modality. Less attention has been paid to maladaptive plasticity that may arise as a result of ectopic innervation from other modalities. Using ferrets in which neonata...

متن کاملCochlear Injury and Adaptive Plasticity of the Auditory Cortex
Growing evidence suggests that cochlear stressors as noise exposure and aging can induce homeostatic/maladaptive changes in the central auditory system from the brainstem to the cortex. Studies centered on such changes have revealed several mechanisms that operate in the context of sensory disruption after insult (noise trauma, drug-, or age-related injury). The oxidative stress is central to c...
