The neurophysiological basis of event file coding in response inhibition
Mon-HS2-Talk II-06
Presented by: Astrid Prochnow
As theories describing event file dynamics (Theory of Event Coding (TEC; Hommel et al. 2001), Binding and Retrieval in Action Control (BRAC; Frings et al. 2020)) aim to provide a comprehensive explanation of how the mind works, their principles should apply not only in the frequently studied situations of response selection, but also in other domains such as response inhibition. In this talk, the relevance of event file coding to response inhibition and its neural underpinnings will be illustrated using EEG data that have been examined using a wide range of analysis methods including network analysis and MVPA. Moreover, the influence of pre-trial dynamics as well as manipulations of the catecholaminergic system on event file coding in response inhibition was investigated. The results show that depending on the event file coding requirements different mechanisms are used to process stimulus features, and thus to inhibit responses successfully despite conflicting information, as reflected, for instance, in a seesaw-like relationship between the theta and alpha frequency bands. Thus, examining the dynamics of event files in response inhibition and their neural basis demonstrates the applicability of event file coding theories such as TEC and BRAC in different cognitive domains and offers a contribution to more sophisticated theory building integrating cognitive and neurophysiological elements.
