S.L. Fairhall, K.B. Porter, C. Bellucci, M. Mazzetti, C. Cipolli, M.I. Gobbini
2017 NeuroImage  
To critically test the broader role of core face-system in person perception, we examined the role of the core system during the perception of others in 7 congenitally blind individuals and 15 sighted  ...  A B S T R A C T Recent evidence suggests that the function of the core system for face perception might extend beyond visual faceperception to a broader role in person perception.  ...  Acknowledgement Above all, we would thank the blind participant who travelled from across Italy to take part in this study.  ...

Use dependent limb dominence and somatosensory evoked potentials (SEPs) in the congenitally blind

Dayananda Giriyappa, Roopakala M. Subramanyam, Rajeev Sharma, Srinivasa Rangasetty
2013 Al Ameen Journal of Medical Sciences  
Use-dependent reorganization and neural plasticity changes occur as a consequence of many events, including the normal development and maturation of the organism, the acquisition of new skills.  ...  Results: The SEP-N20 amplitude was significantly increased in the congenitally blind (p < 0.0001 for right index finger and p < 0.005 for left index finger).  ...  The adaptive advantage of neural plasticity probably links to fine tuning development of Braille reading in the congenitally blind.  ...

Neuroplasticity in adult human visual cortex

Elisa Castaldi, Claudia Lunghi, Maria Concetta Morrone
2020 Neuroscience and Biobehavioral Reviews  
Next, we discuss how the brain circuits reorganize when blindness occurs and when visual stimulation is partially restored by means of a 'bionic eye' in late blind adults with Retinitis Pigmentosa.  ...  In this review we summarize studies showing that the visual brain of sighted adults retains a type of developmental plasticity, called homeostatic plasticity, and this property has been recently exploited  ...  In the second part we discuss the neural changes following blinding diseases and, in particular, the plastic retinotopic remapping of the residual visual input, the cross-modal reorganization and the functional  ...

Compensatory plasticity: time matters

Latifa Lazzouni, Franco Lepore
2014 Frontiers in Human Neuroscience  
However, reorganization remains more pronounced in the congenitally blind.  ...  Plasticity in the human and animal brain is the rule, the base for development, and the way to deal effectively with the environment for making the most efficient use of all the senses.  ...  The neural system has the capacity to adapt to the loss of one modality by undergoing plastic changes in its structure, connectivity, function and neural interactions.  ...

Andrea Leo, Giulio Bernardi, Giacomo Handjaras, Daniela Bonino, Emiliano Ricciardi, Pietro Pietrini
2012 Neural Plasticity  
As BOLD variability reflects neural integration and processing efficiency, these cross-modal plastic changes in the parietal cortex, even if described in a limited sample, reinforce the hypothesis that  ...  this region may play an important role in processing nonvisual information in blind subjects and act as a hub in the cortico-cortical pathway from somatosensory cortex to the reorganized occipital areas  ...  Acknowledgments The authors wish to thank all the volunteers who took part in their studies and the Unione Italiana Ciechi for its support to these projects and the MRI Laboratory at the Fondazione Regione  ...

Auditory and auditory-tactile processing in congenitally blind humans

Kirsten Hötting, Brigitte Röder
2009 Hearing Research  
A growing number of studies have provided evidence that the increased use of the auditory system results in compensatory behavior in the blind.  ...  Neural plasticity at different levels of the auditory processing stream has been linked to these behavioral benefits.
