Speech planning and execution in children who stutter: Preliminary findings from a fNIRS investigation (2021)
Journal Article
Jackson, E. S., Wijeakumar, S., Beal, D. S., Brown, B., Zebrowski, P. M., & Spencer, J. P. (2021). Speech planning and execution in children who stutter: Preliminary findings from a fNIRS investigation. Journal of Clinical Neuroscience, 91, 32-42. https://doi.org/10.1016/j.jocn.2021.06.018

Few studies have investigated the neural mechanisms underlying speech production in children who stutter (CWS), despite the critical importance of understanding these mechanisms closer to the time of stuttering onset. The relative contributions of sp... Read More about Speech planning and execution in children who stutter: Preliminary findings from a fNIRS investigation.

Processing pipeline for image reconstructed fNIRS analysis using both MRI templates and individual anatomy (2021)
Journal Article
Forbes, S. H., Wijeakumar, S., Eggebrecht, A. T., Magnotta, V. A., & Spencer, J. P. (2021). Processing pipeline for image reconstructed fNIRS analysis using both MRI templates and individual anatomy. Neurophotonics, 8(2), Article 025010. https://doi.org/10.1117/1.nph.8.2.025010

Significance: Image reconstruction of fNIRS data is a useful technique for transforming channel-based fNIRS into a volumetric representation and managing spatial variance based on optode location. We present an innovative integrated pipeline for imag... Read More about Processing pipeline for image reconstructed fNIRS analysis using both MRI templates and individual anatomy.

Home assessment of visual working memory in pre‐schoolers reveals associations between behaviour, brain activation and parent reports of life stress (2021)
Journal Article
McKay, C., Shing, Y. L., Rafetseder, E., & Wijeakumar, S. (2021). Home assessment of visual working memory in pre‐schoolers reveals associations between behaviour, brain activation and parent reports of life stress. Developmental Science, 24(4), Article e13094. https://doi.org/10.1111/desc.13094

Visual working memory (VWM) is reliably predictive of fluid intelligence and academic achievements. The objective of the current study was to investigate individual differences in pre-schoolers’ VWM processing by examining the association between beh...

The functional brain networks that underlie visual working memory in the first two years of life (2020)
Journal Article
Delgado Reyes, L., Wijeakumar, S., Magnotta, V. A., Forbes, S. H., & Spencer, J. P. (2020). The functional brain networks that underlie visual working memory in the first two years of life. NeuroImage, 219, Article 116971. https://doi.org/10.1016/j.neuroimage.2020.116971

Visual working memory (VWM) is a central cognitive system used to compare views of the world and detect changes in the local environment. This system undergoes dramatic development in the first two years; however, we know relatively little about the...

Early adversity in rural India impacts the brain networks underlying visual working memory (2019)
Journal Article
Wijeakumar, S., Kumar, A., M. Delgado Reyes, L., Tiwari, M., & Spencer, J. P. (2019). Early adversity in rural India impacts the brain networks underlying visual working memory. Developmental Science, 22(5), Article e12822. https://doi.org/10.1111/desc.12822

© 2019 The Authors. Developmental Science Published by John Wiley & Sons Ltd. There is a growing need to understand the global impact of poverty on early brain and behavioural development, particularly with regard to key cognitive processes that em...

A fNIRS Investigation of Speech Planning and Execution in Adults Who Stutter (2019)
Journal Article
Jackson, E. S., Wijeakumar, S., Beal, D. S., Brown, B., Zebrowski, P., & Spencer, J. P. (2019). A fNIRS Investigation of Speech Planning and Execution in Adults Who Stutter. Neuroscience, 406, 73-85. https://doi.org/10.1016/j.neuroscience.2019.02.032

© 2019 IBRO Our study aimed to determine the neural correlates of speech planning and execution in adults who stutter (AWS). Fifteen AWS and 15 controls (CON) completed two tasks that either manipulated speech planning or execution processing loads....

Tracing the evolutionary trajectory of verbal working memory with neuro-archaeology (2018)
Journal Article
Putt, S. S., & Wijeakumar, S. (2018). Tracing the evolutionary trajectory of verbal working memory with neuro-archaeology. Interaction Studies, 19(1-2), 272-288. https://doi.org/10.1075/is.17042.put

We used optical neuroimaging to explore the extent of functional overlap between working memory (WM) networks involved in language and Early Stone Age toolmaking behaviors. Oldowan tool production activates two verbal WM areas, but the functions of t... Read More about Tracing the evolutionary trajectory of verbal working memory with neuro-archaeology.
