The work performed so far on the project has made progress beyond the state of the art in mind-wandering research by using a combination of multivariate and univariate analyses to identify neurocognitive markers of intentional and unintentional mind-wandering. The use of scalp EEG recordings in conjunction with multidimensional reports of ongoing thought has allowed for a more in-depth understanding of the electrophysiological signatures associated with different types of mind-wandering. The results have shown that on-task, intentional, and unintentional mind-wandering exhibit distinct signatures in the low frequency range, with increased features of the theta frequency range being most discriminative between on-task and off-task states, and features within the alpha band being characteristic of intentional when compared to unintentional mind-wandering.
The ongoing study using tACS and TMS over the mPFC to modulate underlying neurocognitive processes has the potential to improve attention in both health and disease. This could have significant impacts on society, including improved productivity and cognitive performance in individuals and a decrease in the burden of attention-related disorders. The results of this study have the potential to contribute to the development of new treatments for attention-related disorders, which could have a positive socio-economic impact by reducing healthcare costs and improving the quality of life for individuals affected by these disorders. Additionally, the findings of this study could also have wider societal implications, such as improving our understanding of the underlying mechanisms of attention and the role of the mPFC in mind-wandering, which could lead to further advancements in the field. Overall, the prospective results include the completion of the study using tACS and TMS to modulate neurocognitive processes associated with intentional and unintentional mind-wandering.
The project team expects to gain insights into the underlying neural mechanisms of attention and the role of the mPFC in mind-wandering, which could be used to develop new interventions for attention-related disorders. The potential impacts of this project on society are significant, including improved productivity and cognitive performance in individuals and a reduction in the burden of attention-related disorders. The project's findings could also have broader societal implications, leading to further advancements in the field of cognitive and clinical neuroscience. The team plans to disseminate the project's results through peer-reviewed publications and conference presentations, ensuring that the findings are accessible to the scientific community and the broader public.
