Differential activity in Heschl's gyrus between deaf and hearing individuals is due to auditory deprivation rather than language modality

Velia Cardin, Rebecca C. Smittenaar, Eleni Orfanidou, Jerker Rönnberg, Cheryl M. Capek, Mary Rudner, Bencie Woll
2016 NeuroImage  
Results show that differences between hearing and deaf individuals are due to a reduction in activation caused by visual stimulation in the hearing group, which is more significant in Te1.0 than in Heschl's  ...  Furthermore, differences between deaf and hearing groups are due to auditory deprivation, and there is no evidence that the modality of language used by deaf individuals contributes to crossmodal plasticity  ...  We specially thank all the deaf and hearing participants who took part in the study.  ...

Enhanced peripheral visual processing in congenitally deaf humans is supported by multiple brain regions, including primary auditory cortex

Gregory D. Scott, Christina M. Karns, Mark W. Dow, Courtney Stevens, Helen J. Neville
2014 Frontiers in Human Neuroscience  
Our results using individually-defined primary auditory cortex (Heschl's gyrus) indicate that fMRI signal change for more peripheral stimuli was greater than perifoveal in deaf but not in hearing participants  ...  In addition to reorganized auditory cortex (cross-modal plasticity), a second gap in our understanding is the contribution of altered modality-specific cortices (visual intramodal plasticity in this case  ...  It is important to define Heschl's gyrus individually due to it's high level of anatomical variability.  ...

Compensatory Plasticity in the Deaf Brain: Effects on Perception of Music

Arla Good, Maureen Reed, Frank Russo
2014 Brain Sciences  
This shift, referred to as compensatory plasticity, results in a unique sensory experience for individuals who are deaf, including the manner in which music is perceived.  ...  When one sense is unavailable, sensory responsibilities shift and processing of the remaining modalities becomes enhanced to compensate for missing information.  ...  Acknowledgments We would like to thank Deborah I. Fels and three anonymous reviewers for comments on earlier versions of this manuscript.  ...

Topographical functional connectivity patterns exist in the congenitally, prelingually deaf

Ella Striem-Amit, Jorge Almeida, Mario Belledonne, Quanjing Chen, Yuxing Fang, Zaizhu Han, Alfonso Caramazza, Yanchao Bi
2016 Scientific Reports  
These findings suggest that large-scale tonotopic-based FC does not require sensory experience to develop, and is retained despite life-long auditory deprivation and cross-modal plasticity.  ...  Furthermore, as the topographic FC is retained to varying degrees among the deaf subjects, it may serve to predict the potential for auditory rehabilitation using cochlear implants in individual subjects  ...  Women in Science to ESA, and the Fundação BIAL grant 112/12 ( to JA.  ...

Sensory experience modulates the reorganisation of temporal auditory regions for executive processing [article]

Barbara Manini, Valeria Vinogradova, Bencie Woll, Donnie Cameron, Martin Eimer, Velia Cardin
2021 bioRxiv   pre-print
We also observed recruitment of auditory temporal regions during planning, but only in deaf individuals with the highest language scores, suggesting differential use of linguistic skills to support EF.  ...  Using fMRI, we investigated how early deafness and consequent varied language experience influence crossmodal plasticity and the organisation of executive functions (EF) in the adult brain.  ...  Acknowledgments The authors would like to specially thank all the deaf and hearing participants who took part in this study.  ...

Comparing the Effects of Auditory Deprivation and Sign Language within the Auditory and Visual Cortex

Ione Fine, Eva M. Finney, Geoffrey M. Boynton, Karen R. Dobkins
2005 Journal of Cognitive Neuroscience  
Hearing signers did not show visual responses in the auditory cortex, indicating that cross-modal plasticity can be attributed to auditory deprivation rather than sign language experience.  ...  & To investigate neural plasticity resulting from early auditory deprivation and use of American Sign Language, we measured responses to visual stimuli in deaf signers, hearing signers, and hearing nonsigners  ...  Acknowledgments This work was supported by an NSF grant to KRD and an NRSA grant to EMF.  ...
