2020 NeuroImage  
We investigated brain and behavioural changes in sighted adults during 8-months training of tactile Braille reading whilst monitoring brain structure and function at 5 different time points.  ...  A growing body of empirical evidence supports the notion of diverse neurobiological processes underlying learning-induced plasticity changes in the human brain.  ...  Conclusions In conclusion, by combining a longitudinal and multi-contrast MRI design, our study provides unique insight into the dynamics of neuroplasticity during human learning.  ...

2008 PLoS ONE  
Following the five-day period, blindfolded subjects performed better on a Braille character discrimination task.  ...  The speed and dynamic nature of the observed changes suggests that normally inhibited or masked functions in the sighted are revealed by visual loss.  ...  and the Carroll Center for the Blind in Newton, MA, for their invaluable advice, service and assistance in carrying out the study.  ...

Neuroplasticity in adult human visual cortex [article]

Elisa Castaldi, Claudia Lunghi, Maria Concetta Morrone
2019 arXiv   pre-print
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  ...  The primary visual cortex in these patients slowly became activated by the artificial visual stimulation, indicating that sight restoration therapies can rely on a considerable degree of spared plasticity  ...  Hopefully in the next decades we will have the complete approach to rescue visual function, facilitating the adult brain to learn to "see" again, even after several years of blindness or abnormal visual  ...

Working Memory Training Integrates Visual Cortex into Beta-Band Networks in Congenitally Blind Individuals [article]

Johanna M. Rimmele, Helene Gudi-Mindermann, Guido Nolte, Brigitte Roeder, Andreas K. Engel
2017 bioRxiv   pre-print
In the sighted, theta-band connectivity increased between brain areas involved in auditory working memory (inferior frontal, superior temporal, insular cortex).  ...  In the blind, beta-band networks largely emerged during the training, and connectivity increased between brain areas involved in auditory working memory and the visual cortex.  ...  This approach benefits from the intra-subject paradigm that investigates changes across pre-post sessions, while the within-subject normalization at the same time isolates task-related functional connectivity  ...

Negative BOLD in Sensory Cortices During Verbal Memory: A Component in Generating Internal Representations?

Haim Azulay, Ella Striem, Amir Amedi
2009 Brain Topography  
In sighted subjects, both auditory and visual areas were robustly deactivated during memory retrieval, whereas in the blind the auditory cortex was deactivated while visual areas, shown previously to be  ...  However the brain mechanisms behind this phenomenon remain poorly understood.  ...  During each epoch, all subjects (sighted and blind) were asked to recall nine words from one of four lists, which had been learned in advance (1 week before the scan).  ...

Experience-Related Structural Changes of Degenerated Occipital White Matter in Late-Blind Humans – A Diffusion Tensor Imaging Study

Susanne Dietrich, Ingo Hertrich, Vinod Kumar, Hermann Ackermann, Hao Huang

Somatosensory processes subserving perception and action

H. Chris Dijkerman, Edward H. F. de Haan
2007 Behavioral and Brain Sciences  
In addition, we find a second division between tactile information processing about external targets in service of object recognition and tactile information processing related to the body itself.  ...  Further, tactile exploration of the characteristics of external objects can result in conscious perceptual experience and stimulus or object recognition.  ...  During tactile shape comparison with Braille characters, lately blind subjects (i.e., those with late onset of blindness) who had never learned Braille showed the activation of the association visual cortex  ...
