The Benefit of Cross-Modal Reorganization on Speech Perception in Pediatric Cochlear Implant Recipients Revealed Using Functional Near-Infrared Spectroscopy (2020)
Journal Article
Mushtaq, F., Wiggins, I. M., Kitterick, P. T., Anderson, C. A., & Hartley, D. E. H. (2020). The Benefit of Cross-Modal Reorganization on Speech Perception in Pediatric Cochlear Implant Recipients Revealed Using Functional Near-Infrared Spectroscopy. Frontiers in Human Neuroscience, https://doi.org/10.3389/fnhum.2020.00308

Cochlear implants (CIs) are the most successful treatment for severe-to-profound deafness in children. However, speech outcomes with a CI often lag behind those of normally-hearing children. Some authors have attributed these deficits to the takeover...

Evaluating time-reversed speech and signal-correlated noise as auditory baselines for isolating speech-specific processing using fNIRS (2019)
Journal Article
Mushtaq, F., Wiggins, I. M., Kitterick, P. T., Anderson, C. A., & Hartley, D. E. H. (2019). Evaluating time-reversed speech and signal-correlated noise as auditory baselines for isolating speech-specific processing using fNIRS. PLoS ONE, 14(7), Article e0219927. https://doi.org/10.1371/journal.pone.0219927

Evidence using well-established imaging techniques, such as functional magnetic resonance imaging and electrocorticography, suggest that speech-specific cortical responses can be functionally localised by contrasting speech responses with an auditory...

Preoperative brain imaging using functional near-infrared spectroscopy helps predict cochlear implant outcome in deaf adults (2019)
Journal Article
Anderson, C. A., Wiggins, I. M., Kitterick, P. T., & Hartley, D. E. (2019). Preoperative brain imaging using functional near-infrared spectroscopy helps predict cochlear implant outcome in deaf adults. Journal of the Association for Research in Otolaryngology, 20(5), 511–528. https://doi.org/10.1007/s10162-019-00729-z

Currently it is not possible to accurately predict how well a deaf individual will be able to understand speech when hearing is (re)introduced via a cochlear implant. Differences in brain organisation following deafness are thought to contribute to v...

Cortical correlates of speech intelligibility measured using functional near-infrared spectroscopy (fNIRS) (2018)
Journal Article
Lawrence, R. J., Wiggins, I. M., Anderson, C. A., Davies-Thompson, J., & Hartley, D. E. (2018). Cortical correlates of speech intelligibility measured using functional near-infrared spectroscopy (fNIRS). Hearing Research, 370, 53-64. https://doi.org/10.1016/j.heares.2018.09.005

Functional neuroimaging has identified that the temporal, frontal and parietal cortex support core aspects of speech processing. An objective measure of speech intelligibility based on cortical activation in these brain regions would be extremely use...

Adaptive benefit of cross-modal plasticity following cochlear implantation in deaf adults (2017)
Journal Article
Anderson, C. A., Wiggins, I. M., Kitterick, P. T., & Hartley, D. E. H. (2017). Adaptive benefit of cross-modal plasticity following cochlear implantation in deaf adults. Proceedings of the National Academy of Sciences, 114(38), 10256-10261. https://doi.org/10.1073/pnas.1704785114

© 2017, National Academy of Sciences. All rights reserved. It has been suggested that visual language is maladaptive for hearing restoration with a cochlear implant (CI) due to cross-modal recruitment of auditory brain regions. Rehabilitative guideli...

Plasticity in bilateral superior temporal cortex: Effects of deafness and cochlear implantation on auditory and visual speech processing (2016)
Journal Article
Anderson, C. A., Lazard, D. S., & Hartley, D. E. (2017). Plasticity in bilateral superior temporal cortex: Effects of deafness and cochlear implantation on auditory and visual speech processing. Hearing Research, 343, 138-149. https://doi.org/10.1016/j.heares.2016.07.013

While many individuals can benefit substantially from cochlear implantation, the ability to perceive and understand auditory speech with a cochlear implant (CI) remains highly variable amongst adult recipients. Importantly, auditory performance with... Read More about Plasticity in bilateral superior temporal cortex: Effects of deafness and cochlear implantation on auditory and visual speech processing.
