چکیده:
The brain's functions hinge on millions of neurons' activities, tied to cognitive aspects like memory and perception. Studying brain performance via non-invasive technologies stands as a pivotal aspect of neuroscience. Analyzing brain waves during rest versus cognitive tasks offers practical insights for modeling research. Results indicate regions linked to cognition align with cognitive duties. Brain waves dynamically vary, revealing diverse responses to emotions in distinct brain regions.

(2021), studied an EEG exploration dataset involving patients engaged in arithmetic subtractions to gain insights into potential trends and the correlation between changes in the randomness pattern of the signal, They compared the EEG signal for subjects at rest and during activity, attempting to identify any indications of the subjects' performance, their results revealed that upon initial analysis, the rest and activity datasets appear similar; however, the overall picture shifts when considering the power levels associated with each type of brain wave (theta, alpha, beta, and gamma) [9].
The aim of current study is to delve into the intricate relationship between brain activity and cognitive functions, exploring the nuances of EEG patterns to provide a comprehensive understanding.
(2021), conducted Power spectral densities (PSDs) and ARIMA and ARFIMA Models to explores extant electroencephalogram (EEG) signals in search of patterns that could differentiate subjects undertaking mental tasks and reveals insights on said data and they analysis some variable parameters including 1) significant differences between the electrical activities for subjects at rest and during activity, 2) categorising subjects’ performance groups (good, average, and poor) based solely on EEG data, 3) checking for differences in the activity of different brain areas [9].
The study's use of frequency- and time-based methods to discern cognitive patterns sheds light on brain activity during mental tasks, offering insights into alpha and gamma wave activity.
