Role of the EEG Theta Network During Software Production: A Connectivity Study

Software programming is an acquired evolutionary skill originating from consolidated cognitive functions (i.e., attentive, logical, coordination, mathematic calculation, and language comprehension), but the underlying neurophysiological processes are still not completely known. In the present study, we investigated and compared the brain activities supporting realistic programming, text and code reading tasks, analyzing Electroencephalographic (EEG) signals acquired from 11 experienced programmers. Multichannel spectral analysis and a phase-based effective connectivity study were carried out. Our results highlighted that both realistic programming and reading tasks are supported by modulations of the Theta fronto-parietal network, in which parietal areas behave as sources of information, while frontal areas behave as receivers. Nevertheless, during realistic programming, both an increase in Theta power and changes in network topology emerged, suggesting a task-related adaptation of the supporting network system. This reorganization mainly regarded the parietal area, which assumes a prominent role, increasing its hub functioning and its connectivity in the network in terms of centrality and degree.

Automated summary

In this study, EEG signals were analyzed from 11 experienced programmers to investigate brain activities during realistic programming and reading tasks. The results showed that both tasks were supported by modulations of the Theta fronto-parietal network, with parietal areas acting as sources of information and frontal areas acting as receivers. Realistic programming led to increased Theta power and changes in network topology, especially in the parietal area, suggesting task-related adaptation of the supporting network system.
