Why the study?
Analysis of the changes in brain activity between rest and various conditions is an important area of research.
Does multitasking workload change the complexity of EEG signals compared to rest?
Does multitasking workload change the complexity of EEG signals compared to rest?
The complexity of EEG signals is lower during multitasking workload compared to rest.
Multitasking workload is associated with lower EEG complexity; leaves open validation as a cognitive-load biomarker.
Analysis of the changes in brain activity between rest and various conditions is an important area of research. We investigated the changes in brain activity among rest and multitask workload (SIMKAP multitasking test) by quantifying the complexity of EEG signals. The results showed that EEG signals have smaller fractal dimensions, sample entropy, and approximate entropy during the SIMKAP multitasking test than the rest. Therefore, the complexity of EEG signals was lower during the SIMKAP multitasking test than the rest. In further research, we can study the changes in brain activity among other conditions, which has great benefits in decoding brain activity in various conditions.
