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. (in press). Adaptive benefit of cross-modal plasticity following cochlear implantation in deaf adults. Proceedings of the National Academy of Sciences, 114(38), doi:10.1073/pnas.1704785114. ISSN 1091-6490

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 guidelines therefore discourage the use of visual language. Howeve... Read More

Brain activity underlying the recovery of meaning from degraded speech: a functional near-infrared spectroscopy (fNIRS) study (2017)
Journal Article
Wijayasiri, P., Hartley, D. E., & Wiggins, I. M. (2017). Brain activity underlying the recovery of meaning from degraded speech: a functional near-infrared spectroscopy (fNIRS) study. Hearing Research, 351, doi:10.1016/j.heares.2017.05.010. ISSN 0378-5955

The purpose of this study was to establish whether functional near-infrared spectroscopy (fNIRS), an emerging brain-imaging technique based on optical principles, is suitable for studying the brain activity that underlies effortful listening. In an e... Read More

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. (in press). Plasticity in bilateral superior temporal cortex: effects of deafness and cochlear implantation on auditory and visual speech processing. Hearing Research, doi:10.1016/j.heares.2016.07.013. ISSN 0378-5955

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

A synchrony-dependent influence of sounds on activity in visual cortex measured using functional near-infrared spectroscopy (fNIRS) (2015)
Journal Article
Hartley, D., & Wiggins, I. (2015). A synchrony-dependent influence of sounds on activity in visual cortex measured using functional near-infrared spectroscopy (fNIRS). PLoS ONE, 10(3), doi:10.1371/journal.pone.0122862

Evidence from human neuroimaging and animal electrophysiological studies suggests that signals from different sensory modalities interact early in cortical processing, including in primary sensory cortices. The present study aimed to test whether fun... Read More
