“…Particularly, the electroencephalography (EEG) is widely used for the investigation of brain activity related to the exposure of natural settings ( Grassini et al, 2022 ), providing an important source of information on changes in neurophysiological dynamics associated with stress-related processes ( Alonso et al, 2015 ; Giannakakis et al, 2019 ; Saeed et al, 2020 ; Massullo et al, 2022 ). More specifically, compared to the traditional visual EEG scoring, through quantitative EEG (qEEG; i.e., numerical computations of parameters from the EEG data) it is possible to estimate different parameters, such as EEG power spectra (i.e., the power distribution of EEG series in the frequency domain), that offer a significant source of information in terms of brain activity ( Thatcher, 2010 ; Lehembre et al, 2012 ).…”
