Description: In order to analyze and detect ERD/ERS responses in film spectators to shot changes by cut, we developed a methodology based on comparisons of recorded EEG signals, with the aim of isolating these neuronal responses from other inputs not related to the cut. This system of comparing pairs of signals using permutation tests, the Spearman correlation, and slope analysis is implemented in an automated way through sliding windows, analyzing all the registered electrodes signals at all the frequency bands defined. Through this methodology, we are able to locate, identify, and quantify the variations in neuronal rhythms in specific cortical areas and frequency ranges with temporal precision. Our results detected that after a cut there is a synchronization in theta rhythms during the first 188 ms with left lateralization, and also a desynchronization between 250 ms and 750 ms in the delta frequency band. The cortical area where most of these neuronal responses are detected in both cases is the parietal area. Furthermore, as this article seeks to show that neurocinematics would profit from referring to classical film theory in addition to neuroscientific knowledge, in our discussion we link the neuroscientific interpretation of the results to the theoretical approaches to film editing of authors such as Mitry, Deleuze, Burch, and Eisenstein.
